Best Paid Antivirus

All Windows PCs need the best antivirus software, even if that software is free. The Windows Defender software built into Windows 10 is very good, but although it defends itself against other free competitors, it cannot quite match the features or protection of the best paid antivirus offerings.

Our first choice for the best antivirus is Bitdefender's Windows range, which offers you excellent protection against malware, a full set of additional features (including an enhanced web browser, webcam protection and file encryption) and an easy-to-use interface.

Just behind Bitdefender are Kaspersky, whose entry-level paid program is the best deal in antivirus software, and Norton, which offers excellent protection with optional LifeLock identity protection and unlimited VPN service.

For the best free antivirus software we liked Avast, which barely surpassed Kaspersky for first place. Both offer excellent protection against malware without slowing down your system, but Kaspersky allows you to schedule scans and has a fast scan option.

Our free rankings immediately follow our paid rankings below.

1. total AV

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices Up to 6 devices
  • Protection against ransom and phishing software
  • Privacy Tools
  • VPN
  • 30-day money back guarantee
  • Secure payment
  • Simple to use
  • Fast
  • Password Manager
  • Very affordable price

TotalAV is a complete antivirus software suite that has a lot to offer, including a free version and a very comprehensive paid version. The paid version of TotalAV costs only 19€ and includes protection against viruses, spyware, ransomware, phishing and other forms of malware.

After a few years on the market and some negative feedback, TotalAV has changed its software, billing practices and refund policy. Today it is one of the most efficient services on the marketThe after-sales service is very reactive in case of problems (which are quite rare). The antivirus is very simple to handle and it runs continuously in the background without taking a lot of resources.

The paid version offers unique features that set it apart from some of the major brands in the industry, which is why we highly recommend upgrading to the premium version for optimal protection. You can read our opinion on Total AV.


2. Bitdefender Antivirus Plus 2020

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices Up to 10 devices
  • Protection against ransom software
  • Privacy Tools
  • VPN
  • Safepay
  • Abstract
  • Password Manager
  • Cheap subscription
  • May be resource-hungry

Bitdefender has been one of the most popular antivirus products over the past few years, and for good reason. A relatively new company compared to others in the antivirus field, Bitdefender has quickly established itself as one of the leading brands with over half a billion active installations/users to date.

There are 17 products to choose from, a number of which are intended for personal use (the types involved will be discussed!) You can protect your PC, Mac and Android with BitDefender.

Bitdefender's antivirus products have become one of the most respected brands in the industry, but how do you get there in 2019? Are they still one of the best choices?

You can find many examples of organizations and reports praising Bitdefender for the reliability and effectiveness of its product, backed by an impressive collection of awards based on the software's ability to detect malware and ignore harmless software. Antivirus reliability should not be a concern at all when considering Bitdefender.

It is also very easy to use. The user interface is very simple and easy to understand. Within seconds, you know your current protection level and what is enabled / disabled in terms of functionality. In addition, you can run a scan immediately.

The only potential level of confusion is that of the 3 different types of scans, but a little research on the product can clear this up. You can read our opinion on Bitdefender.


3. Kaspersky Anti-Virus

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices Up to 10 devices
  • One of the most powerful security packages
  • Extremely easy to use
  • Kaspersky's complete suites are more economical
  • Automatic analyses
  • Prevention of cryptomining infections
  • Simplified security management

Kaspersky, founded in 1997 and covering 200 countries and territories is probably the dark horse of all antivirus software, it is not the best known (ranked third largest consumer security company in the world) even with their 400 million users.

Don't forget that AVG has about 200 million "active" users and is probably the most popular software in the world!

Like AVG, Kaspersky offers a wide range of products from total security to password management software and is arguably the best designed software on the market, with its impressive user interface and advanced virus detection algorithms.

In 2014, the company received the "AVTest Best Performance Award" for its minimal impact on system performance in all tests of solutions for home users, demonstrating that they care about the operation of their customers' devices.

This is of course great news for those who are concerned about using software that uses too much memory or processing power.

Kaspersky's detection rates are among the highest of all security software, so you will immediately think it is a good kit, but it can become a nuisance because some reports say that the software is "too secure" and therefore has a detrimental effect on the performance of your machines.

Nevertheless, by tinkering with the settings a little, you can make the software work well, very well in fact, and you can be sure that it will prevent these harmful downloads.

As far as the design of the software itself is concerned, the user interface is very intuitive and easy to use, so that when it comes to tinkering, you should have no problem navigating through the back-end. You can read our view on Kaspersky.


4. Norton AntiVirus Basic

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices : Unlimited device
  • Blocks even new malware
  • Low impact on system resources
  • Browser extensions can be unreliable
  • Advanced Privacy Security

Norton and Symantec broke up. What does that mean to you? Not much, to be honest. Symantec was bought out by Broadcom and now serves only corporate customers. Norton, on the other hand, focuses exclusively on consumers like you and me.

And frankly, it's doing better than ever. Norton, now called NortonLifeLock, is by far one of the most comprehensive security software available on the market. You can read our opinion on Norton.


Panda Dome Antivirus Pro 5.

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices Up to 5 devices
  • Lots of features
  • Can cover an unlimited number of devices
  • The interface won't be for everyone.
  • Protection test results are inconsistent
  • Process monitor
  • URL filtering
  • Bootable USB spare key

Panda Antivirus offers excellent protection at a very competitive price and is a safe choice for Windows and Android, and includes a free VPN for both.

To help you decide if Panda Anti-Virus is right for you, we have analyzed it thoroughly.

1. protection against known malware

The key word here is "known". Malware and anti-malware are locked in a cat-and-mouse game. When new malware is developed, the antivirus tries to discover and eliminate it.

When a new malware threat is discovered, its digital signature is downloaded into a huge database, enabling the antivirus to detect malware much faster in the future.

This is the classic method of virus analysis, called signature-based detection.

2. protection against unknown malware

Before a malware signature can be downloaded into the database, it must first be discovered. This means that there was a period during which the malware was "unknown". It had simply never been encountered before.

To detect unknown malware, antivirus software uses a different method. This method is called "heuristic file analysis". Here, antivirus software looks for suspicious behavior rather than digital signatures.

For example, if a program tries to replicate itself very quickly on a network, this is suspicious. Normal software doesn't do this, so this program would be flagged as potential malware.

3. protection against user-centric threats

There are a lot of online scams. A famous example is a phishing email that seems to come from PayPal and asks you to verify your account. Of course, this email is not from PayPal, it is actually trying to trick you into giving your account details.

To protect users from such threats, file scanning methods are unnecessary. Instead, antivirus software has developed other features, such as anti-phishing tools and web advisers. You can read our view on Panda.


McAfee Total Protection

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices : Unlimited
  • Very simple
  • Good value for money
  • Subject to false positives
  • Protection of navigation and banking
  • Protection against ransomware

One of the biggest brands in the antivirus market since its inception, Mcafee Antivirus (named after the company founded by the famous product creator, John McAfee, who resigned from the company in 1994) quickly reached heights in the late 1990s as the most powerful antivirus software on the market.

Now owned by Intel Security Group (purchased in 2010 for a modest $7.68 billion), Mcafee's antivirus products continue to be a force in the market, building on nearly 30 years of experience in PC protection products.

With an arsenal of 30 products, McAfee has a lot to offer in the world of cyber protection, from protecting your mobile phone to protecting large corporate server bases, but what can they do for you in protecting your computer, and are they worth a try?

As mentioned in the "Features" section, Mcafee antivirus software is generally very reliable and, in the most recent test, above industry standard.

According to usability testing, the same is true for the product's ease of use. With no false detection of legitimate software as malware, McAfee Antivirus is well ahead of the industry average (5 out of a possible 1,328,235).

This provides the user with an excellent experience and no false detection of harmless software, which is all too common in antivirus products. The product's user interface is very simple and easy to navigate, unlike other antivirus software with a good feature set. You can read our opinion on McAfee.


7. ESET NOD32 Antivirus

  • Operating system : Windows, Mac, Android
  • Maximum number of devices Up to 4 devices
  • Highly configurable
  • Device access control
  • Relatively expensive
  • Not for beginners
  • Ransomware Shield
  • UEFI Scanner
  • Exploit Blocker
  • Cloud Analysis

Your antivirus must eliminate any malware infestation and repel any new attack, that's the basics. Some products stick to these essential activities, others, like ESET NOD32 antivirus, go far beyond.

Among other additional features, NOD32 includes a host intrusion prevention system, a scanner for your PC firmware and an elaborate device control system. It performed well in our tests, although some of its additional functions may be too complex for the average user.

Almost all antivirus programs have the ability to detect and remove potentially unwanted applications (PUAs) - programs that, while not actively malicious, cause problems that outweigh any virtues they may have.

Some remove these PUAs by default, while others leave them alone. NOD32 makes you actively choose to remove the PUAs during installation. I have enabled PUA detection, and I advise you to do the same. After installation, NOD32 starts a scan; for test purposes, I have interrupted this initial scan, saving a full scan for later.

The main window contains an image of ESET's blue-eyed cyborg mascot. To start a scan or update, you can use either the menu on the left or a pair of large blue panels at the bottom of the window.

In case of configuration problems, the green safety strip turns red. And if ESET requires your attention - to show the results of a completed scan, for example - you see a small number next to the corresponding menu item. You can read our opinion about Eset Nod32.


8. Thor Home Antivirus

  • Operating system Windows
  • Maximum number of devices 3 PCS
  • An excellent Antivirus
  • Enjoy the power of Avira
  • Powerful URL filter
  • Automatic software updates

There are a large number of powerful security tools on the market, and some of them are very expensive, and while I can't admit that this software is the "most advanced security suite" ever built, I can highly recommend Thor Premium from Heimdal Security for its next generation detection capabilities.

Heimdal Security's marketing team likes to boast that its software is "the most powerful and advanced security suite" ever built, but most of the time I find these claims exaggerated.

The next-generation Thor Vigilance Suite offers some of the most advanced malware detection capabilities of any product on the market, and I was immediately impressed by the fact that it intercepts all the samples I tested, including macro viruses, pieces of malware and a Trojan horse.

The on-demand analysis tool allows users to choose from seven unique analysis methods, providing the most comprehensive range of options to date.

The list includes a quick scan, which scanned my directories in less than five minutes, and an active process scan, which checks all running processes for threats.

The Danish company integrates impressive detection tools into Thor Premium Home, including low-level monitoring of packet exchanges and detection of second-generation malware.


9. Webroot SecureAnywhere AntiVirus

  • Operating system : Windows and Mac
  • Maximum number of devices Up to 5 devices
  • Extremely light on system resources
  • Lightning fast
  • Permanent security
  • Identity Protection
  • Real-time anti-phishing
  • Firewall monitor

In the early days of viruses and other malware, antivirus programs relied on ever-increasing signature databases to identify dangerous files. Polymorphic malware thwarted signatures, so security companies developed heuristic and behavioral-based detection methods.

This proliferation of techniques has sometimes resulted in very large programs. Rather than developing to instantly detect each new attack, Webroot SecureAnywhere AntiVirus monitors unknown programs until its cloud-based brain comes to a judgment.

If he refuses, the tiny local program eliminates the attacker and reverses his actions. It's a very unusual system, but tests prove it does the job, and does it well.

Webroot SecureAnywhere antivirus does not align with the testing methods used by many independent labs, although it is starting to gain momentum with some of them. In my own field tests, it scored perfect for malware protection and a very good score for antiphishing.

His score against malware-hosted URLs was about the same, but when we triggered a more intense scan, the score soared.

And we have empirically demonstrated that, under the right circumstances, it can reverse the damage caused by ransom programs. It remains an excellent antivirus, sure to please those who want good things in a small package.


10. Trend Micro Antivirus+ Security

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices Up to 5 devices
  • Affordable prices
  • Easy to use
  • Strong protection
  • Could slow you down
  • Visible limitation of options
  • Protection against ransomware
  • Protection against email scams
  • Pay Guard

In addition to effective malware protection, Trend Micro Antivirus+ Security offers layered ransom protection, firewall booster, online banking protection, and more.

Any worthwhile antivirus utility must eliminate existing malware infestations and fight any new attacks; this is the minimum to consider, and some, like Trend Micro Antivirus+ Security, go far beyond this minimum.

The "plus" in its name refers to a host of additional features, including a firewall booster, layered protection against ransom software and an enhanced browser for online banking. Add to this an effective basic antivirus system and you have a product that is worth looking at.

Trend Micro Antivirus+ Security scores highly in our malicious URL blocking and antiphishing tests, but it does not score well in our practical malware protection tests, and it also receives a range of excellent to poor scores in independent lab tests.

The new Fraud Buster for webmail, browser protection for financial transactions and an Outlook-specific spam filter all justify the "+" in the product name.

Keep in mind, however, that there is no volume discount, so if you need to protect multiple PCs, you will need to upgrade to a Trend Micro suite or choose another antivirus product.

Antivirus software is essential if you plan to connect to the Internet, due to the proliferation of contaminated advertising iframes, malware-laden spam and drive-by downloads that can affect even the most legitimate, honest and popular websites.

The following scans are based on data collected during the first six months of 2019. Our scans bring together data from the AV-TEST and AV-Comparatives security and malware testing labs to evaluate the performance of each antivirus program.

They test the software's ability to correctly identify malicious files and websites, protect against drive-by downloads, and avoid false positive detections when benign software is mistakenly blocked as malicious.

Both labs also evaluate the impact of antivirus software on system performance. In addition to data from these established test facilities, we test each antivirus suite ourselves to see how it works and what features it has.

1. free Avast Antivirus

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices : Unlimited free version
  • Does not slow down your computer
  • Good protection against viruses
  • Irritating privacy settings
  • Virus detection
  • Game mode
  • Password Manager
  • Malware Analyzer

You'd expect a free antivirus to offer only the most basic protection, with advanced features as a bonus for paying customers, but in reality, most popular free antivirus products offer complete protection and a ton of additional features.

Avast Free Antivirus offers you more than many competing commercial products. In addition to excellent antivirus protection, it adds a network security scanner, password manager, browser protection, and much more. It's an amazing set of security features, considering that this product is free.

Avast acquired competitor AVG, a company specializing in free antivirus products, in 2016. Fans of both companies can rest easy; three years later, there are still no plans to merge them into a single product. Both companies have several thousand users worldwide, but each is strong in geographic areas where the other is weak.

And the underlying antivirus engine is exactly the same in Avast and AVG AntiVirus Free, as my tests and independent lab tests have shown.

Avast Free antivirus provides antivirus protection that scores well in my field tests and very good results in independent lab tests, and it offers much more functionality than many competing commercial products, including a network security scanner, password manager, and more.

However, due to the ongoing problems related to the processing of the personal data of its many users, Avast can no longer justify its designation as the best free antivirus. You can read our opinion on Avast.


2. free Kaspersky

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices : Unlimited free version
  • Precise and reliable antivirus engine
  • Easy to use
  • Basic functions only
  • Limited technical support
  • Real time analysis
  • Anti-phishing
  • Mail analysis
  • Protection against spyware

If you're a security-conscious person on a tight budget, you'll appreciate the fact that Kaspersky Security Cloud Free provides you with all the basics of virus protection for free, including a VPN and a small collection of suit-level features.

It is the same malware control technology that gets top marks from independent laboratories. It is true that Kaspersky has not performed as well in our field tests, but when the laboratories all praise a product, we listen. Kaspersky Security Cloud Free is a choice of vendors for free antivirus protection.

Since the product is completely free, you can install it and tap into the tires without spending a penny. But if you do, we also suggest you check out our other top-rated free antivirus utilities. After all, it doesn't cost anything to try them out.

Kaspersky Security Cloud Free offers complete protection against malware and even some features at the appropriate level. It gets very good results from independent labs and won't cost you a penny. You can read our view on Kaspersky.


3. free Avira Antivirus

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices : Unlimited free version
  • Little impact on system performance
  • High detection rates
  • Installer promotes other Avira products
  • Virus detection
  • Protection against phishing
  • embedded VPN
  • System optimization tools

Everyone needs virus protection, even people on a tight budget. Founded in 1986, Avira protects hundreds of millions of users worldwide with its free Avira antivirus.

This product receives excellent marks from independent laboratories and brings with it a collection of related Avira products. It succeeded in blocking access to URLs hosting malware in our tests, but failed in our phishing protection test.

Avira Antivirus gets good marks from independent laboratories, but not as good as the best commercial products, and it scores well in my practical tests for blocking malware and malicious URLs.

The fact that its browser security component only works in Chrome and Firefox poses no problem if one of these browsers is your default browser, and the fact that it can protect you, free of charge, means it's worth a try.

The free Avira antivirus gets excellent ratings from independent laboratories, but it does not score as well in our antiphishing test, and its browser protection only works with Chrome and Firefox. You can read our opinion on Avira.


4. free Bitdefender Antivirus

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices : Unlimited free version
  • Fast scans
  • Excellent virus detection
  • Analyses cannot be scheduled
  • Protection against phishing
  • Behavioural analysis
  • Automatic analysis

The Bitdefender Antivirus Free Edition features a minimalist design and low maintenance. Although the application has no configuration, it automatically scans your machine in the background using a cloud scan and then performs a more thorough scan if it detects malware or a red flag.

The integrated real-time anti-virus shield also blocks malicious URLs and uses behavior-based detection to protect against potential threats. New features include anti-fraud and phishing options that use more advanced filters to warn you of sites known to try to steal identities.

In addition to blocking and removing malware, this lightweight program is also an excellent anti-rootkit and anti-phishing tool, performing the latter task by detecting and blocking fraudulent sites through HTTP-based scanning. You can read our opinion on Bitdefender.


5. Sophos Home

  • Operating system : Windows, Mac, Android and IOS
  • Maximum number of devices : Unlimited free version
  • Simple and non-intrusive
  • Good control of protected devices in the cloud
  • Limited controls for advanced users
  • Protection against phishing
  • Parental Controls
  • Protects up to 10 computers in paid version

Sophos is a big name in anti-virus and security suites for businesses. Despite this commercial focus, you can still get the same enterprise-level protection for your own devices in the form of Sophos Home Free.

It scores well in our practical malware protection test, and it has excellent results in independent lab tests, making it a particularly good choice if you run virus protection for family members or others.

Sophos Home Free has received top marks from two independent laboratories and also scored very well in our field tests. Its phishing protection is good, but not the best. The web content filter is porous, but it's not required for virus protection. If you manage security for others, remote management of this product is a godsend.

Sophos Home Free provides consumers with antivirus protection designed for businesses, including remote management, and scores highly in lab tests and in our own tests.


Free Antivirus Ranking updated in July 2020

Malware, Spyware and Adware Protection

We have tested more than 40 antivirus software in practical tests to help you make the best choice. If you don't have antivirus software, now would be a good time to install one.

We call it antivirus, but in reality, you are unlikely to be hit by a real computer virus. Nowadays, malware is a money-maker, and there is no easy way to profit from the spread of a virus.

Ransom software and Trojans that steal data are much more common, as are bots that allow the bot-herder to rent your computer for malicious purposes. Modern antivirus utilities handle Trojans, rootkits, spyware, adware, ransom software and more.

Some non-standard commercial anti-virus products have proven to be effective enough to score high marks alongside their more traditional counterparts. VoodooShield bases its protection on removing all unknown programs when the computer is vulnerable, for example when connected to the Internet, and also acts to detect known malware. If you have malware, one of the above products should fix the problem.

These commercial products offer protection beyond the antivirus built into Windows 10; the best free antivirus utilities also offer more. However, Microsoft Windows Defender Security Center seems to be doing a little better lately, with very good results from independent test labs. In our field tests, it showed a clear improvement over our previous review, enough to finally raise it to three stars.

Listen to the labs

We take the results reported by independent virus testing laboratories very seriously. The mere fact that a particular vendor's product appears in the results is a kind of vote of confidence. It means that the laboratory considered the product important and the vendor felt that the cost of testing was worth it. Of course, it is also important to get good test scores.

We monitor four laboratories that regularly publish detailed reports: SE Labs, AV-Test Institute, MRG-Effitas and AV-Comparatives. We also note whether vendors have contracted with ICSA Labs for certification. We have designed a system for aggregating their results to get an idea of the quality of the software.

We test defenses against Malware, Spyware and Adware.

We also subject each product to our own practical malware protection test, in part to get an idea of how the product works. Depending on how effectively the product prevents malware from being installed, it can earn points for malware protection.

Our malware protection test necessarily uses the same set of samples for months at a time. To verify support for a brand new malware product, we test each product using 100 new malware hosting URLs provided by MRG-Effitas, noting the percentage of these URLs blocked. Products receive equal credit for preventing access to the malicious URL and for removing the malware during download.

There are some products that get absolutely outstanding marks from independent laboratories, but do not perform as well in our practical tests. In such cases, we rely on the laboratories because they devote far more resources to their testing.

Multi-layer malware protection

Antivirus products are distinguished by going beyond on-demand scanning and real-time protection against malware, some of which evaluate the URLs you visit or that appear in search results using a red-yellow-green color-coding system.

Some actively block processes on your system to prevent connection to known malware hosting URLs or fraudulent pages (phishing).

Software has flaws, and sometimes these flaws affect your security. Prudent users keep Windows and all programs patched, fixing these flaws as soon as possible. The vulnerability scan offered by some antivirus products can verify that all necessary patches are present, and even apply the missing ones.

Spyware comes in many forms, ranging from hidden programs that record all your keystrokes to Trojans that pose as valid programs when mining your personal data.

All antivirus software must deal with spyware, as well as all other types of malware, but some include specialized components dedicated to spyware protection.

You expect a virus scanner to identify and eliminate bad programs, and leave good programs alone. What about unknowns, programs that it can't identify as good or bad?

Behavior-based detection can, in theory, protect you from malware that new researchers have never encountered, but it's not always an unmixed blessing.

It is not uncommon for behavioural detection systems to report many innocuous behaviours performed by legitimate programs.

Whitelisting is another approach to the problem of unknown programs. A whitelisted security system only allows good known programs to run. Unknowns are prohibited. This mode is not suitable for all situations, but it can be useful.

The Sandbox feature allows unknown programs to run, but isolates them from full access to your system so that they cannot cause permanent damage. These different layers are added to enhance your protection against malware.

Firewall, malware protection, etc.

Firewalls and spam filtering are not common anti-virus features, but some of our flagship products include them as a bonus - in fact, some of these anti-virus products are more feature-rich than some products sold as security suites.

Other bonus features include secure browsers for financial transactions, secure deletion of sensitive files, erasing computer tracks and browsing history, virtual keyboard to thwart keyloggers, cross-platform protection, and more.

You'll even find products that enhance their automatic malware protection with the expertise of human security technicians, and of course we've already mentioned sandboxing, vulnerability scanning and application whitelisting.

We are seeing more and more antivirus products adding modules specifically designed to protect against ransomware. Some work by preventing unauthorized changes to protected files. Others monitor suspicious behavior that suggests the existence of malware.

Given the growth of this plague, any additional protection is beneficial.

Beyond Antivirus: VPN

Your anti-virus utility runs in the background to prevent any possibility of malware infestation, but its capabilities do not extend beyond the limits of your computer. When you connect to the Internet in the wilderness you risk the possibility of your data being compromised in transit.

Sticking to HTTPS websites whenever possible can help, but for complete protection of your data in transit, you should install a virtual private network, or VPN. This component is important enough that we are starting to consider it a bonus in some antivirus tools.

Frequently Asked Questions

Below, we have summarized the most frequently asked questions about cybersecurity and the top antivirus software.

What is an antivirus?

Antivirus software helps you fight all forms of malware. The software protects and repels at the same time, which means it helps you avoid the installation of new malware, as well as removing existing malware from your device.

It does this by scanning your system using the signature and file detection methods described in the previous section and offers a wide range of user-oriented protection features such as antiphishing, password managers, etc. Your antivirus can also block certain invasive advertisements such as those on the streaming sites.

What is malware or malicious software?

Classically, malware was used to describe any type of software that could infect your device and cause damage. Typically, this damage includes slowing down your device, stealing sensitive information, or showing you unwanted advertisements.

In the modern era, where cybercriminals not only create malware, but also attempt to manipulate users into providing information, malware has become a much broader term.

Types of Malware

Below we describe many forms of malware, as well as a series of surrounding terms that are not considered malware in the conventional sense, but are nevertheless important to know.

What is an AdWare?

An AdWare is software installed on your device, designed to show you ads in the form of pop-ups or toolbars. These are completely harmless adware. Other versions will track your Internet usage or even monitor your keystrokes to steal sensitive data. An AdWare can be removed by dedicated anti-adware software or good anti-virus software.

What is a Botnet?

Botnet is the abbreviation for Bot Network and is sometimes referred to as an army of zombies. It is a network consisting of a large number of malware-infected devices that can be remotely controlled by a hacker. The purpose of a botnet is to organize DDoS attacks, steal sensitive data or spread other malware.

What is a computer virus?

A computer virus is code or software installed on your device without your knowledge or permission. Computer viruses can be annoying or incredibly destructive. They are designed to spread automatically between computers and networks and include all types of malware. Famous examples are CryptoLocker and Storm Worm.

What is a computer worm?

A computer worm is a form of malicious software that automatically replicates itself and can slow down your computer to incredible proportions.

It is generally disseminated through e-mail attachments and file-sharing networks and may be used by governments in other cases, as if to neutralize the opposing nuclear.

What is a computer exploit?

When software, hardware or a network has a particular vulnerability and a hacker uses it to hack into the system, it is called an exploit. The hacker often uses a piece of code or software to gain control. Vulnerabilities are usually discovered when hackers have already hacked into the system and caused damage.

What is hacking?

Hacking is the manipulation of a computer and its network, often for malicious purposes. By using malicious software that modifies data that travels over the network, a hacker can access information on the system. Using any form of malicious software to achieve an objective is considered hacking.

What is cybercrime?

Cybercrime is any form of digital crime that is carried out using the Internet or electronic devices. In the age of the Internet, cybercrime is one of the most common forms of crime and is growing year after year.

It comes in two main forms: one-off attacks in which sensitive data is stolen and ongoing crimes such as extortion and cyberbullying.

What is a DDoS attack?

Usually, when a consumer website is inaccessible or incredibly slow, it falls victim to a DDoS attack, which stands for Distributed Denial of Service attack. A DDoS attack is executed by overwhelming a website with Internet traffic from thousands of devices, typically malware-infected and remotely controlled devices, also known as Botnet.

What is identity theft?

Identity theft occurs when someone steals your tax, credit card or passport information and impersonates you. The criminal in question opens a new account in your name, such as a mobile phone contract, or uses your existing account, such as your Internet banking credentials, to pay for products and services.

What is a Keylogger?

Keyloggers are a special type of spyware that record the information you enter on your device, allowing criminals to track your activities and steal your passwords, credit card numbers, banking information and more.

What is phishing?

Phishing messages are schemes to trick people into revealing personal information, such as credit card details, bank account numbers or passwords. Often, phishing attacks take the form of emails claiming to come from real organizations such as your bank or PayPal, asking you to validate or update information. For example, you may have WannaCry who's been in the news a lot..

What is Ransomware?

Ransomware, also known as rogueware or scareware, locks your device until you pay a ransom to unlock it. Some of the largest ransom attacks in recent history, such as WannaCry, Petya, Locky, Cerber and CryptoLocker, have made headlines around the world.
