Best Free Malware Removal Tools in 2026: What Still Works

Free malware removal in 2026: the short answer

On Windows, start with the protection you already have. Microsoft says Microsoft Defender Antivirus gives real-time protection with automatic updates and also has strong malware removal features.[7] For a second opinion, Microsoft offers the free Safety Scanner, which finds and removes malware on demand.[7]

The free tools in our original guide below are still a useful starting point, but one entry needs a warning. Kaspersky products stopped receiving updates in the United States on September 29, 2024, after a Commerce Department ban.[8][9] We did not re-test the other tools for 2026, so check each vendor's site for the current free edition.

Timeline: what changed for free antivirus users

What changed since 2024

The biggest change for our list is Kaspersky. The US Bureau of Industry and Security found that Kaspersky's operations in the US posed a national security risk, citing the Russian government's ability to influence the company.[8] Kaspersky can no longer sell its software in the US or provide updates to software already in use there.[8]

People who keep using Kaspersky products in the US face no legal penalty, BIS says.[8] The real problem is protection. Without signature and code updates, which ended on September 29, 2024, the software falls behind new threats.[9] Outside the US this ban does not apply.

Microsoft's own free tools stayed the same in principle. Safety Scanner still scans only when you start it, expires 10 days after download and does not replace an antivirus.[7] Microsoft points users to Defender Antivirus on Windows 11 and Windows 10 for real-time protection.[7]

Scams that pose as free malware removal

Searches for free malware removal attract scammers. This list is our analysis, built on the FTC warning about tech support scams.[2]

• Fake virus alerts. A web page or pop-up says your PC is infected and urges you to download a cleaner or call a number.
• Copycat download sites. Pages that look like a vendor's site but hand out a bundled installer or real malware.
• Fake tech support calls. Callers who claim to be from Microsoft or an antivirus company and ask for remote access or payment.[2]
• Cracked paid antivirus. Free activation keys and cracked installers often carry information stealers.
• Fake cleaners. Programs that report hundreds of problems and only fix them after you pay.

How to remove malware for free, step by step

1. Go offline. If the PC behaves strangely, disconnect it from the internet so malware cannot send data or download more files while you work.

2. Run a full Defender scan. Open Windows Security and run a full scan with Microsoft Defender Antivirus, which Microsoft says has strong removal features.[7]

3. Get a second opinion. Download a fresh copy of Microsoft Safety Scanner or another free tool from its official site. Safety Scanner expires after 10 days, so get a new copy each time.[7]

4. Remove and restart. Act on every detection, restart, and scan again. If a threat comes back, look it up in our virus and malware removal guides.

5. Change passwords. Use a clean device to change your email and banking passwords, then check whether your email appeared in a leak with our leak check.

6. Replace old tools. If your antivirus no longer gets updates, as with Kaspersky in the US since September 29, 2024, switch to a supported product.[8]

What is still unknown

• Which free editions each vendor in our original list still offers in 2026. We did not re-test them and vendors change plans often.
• Whether any other country will follow the US ban on Kaspersky. We found no new decision as of 2026.
• How detection rates of free tools compare in 2026 lab tests. We did not review new lab results for this update.

Our original 2024 report

The text below is our report as first published in 2024. We keep it unchanged for the record; the sections above bring it up to date.

In recent years, cybercrime statistics have been raising serious doubts over the future. After seeing numerous ransomware attacks, data breaches, cryptocurrency mining cases, and phishing attempts, we cannot expect to see fewer dangers in 2024. Actually, it is expected that the situation will become even worse.

However, European GDPR legislation brings new consequences to those who fail to protect people's private information.[1] Additionally, this year security vendors offered new tools capable of blocking websites used for cryptomining, preventing threats before they attack the system, and providing an extra layer for computer and data protection.

Professional malware removal tools might be relatively expensive. Likewise, we have prepared the list of the best free malware removal tools of 2024 to make proof that it is not necessary to make big investments to protect your system from cyber infections. Note that some of the anti-malware programs also have premium versions which can be purchased if want some extra security.

On a final note, we feel obligated to warn you that you should be cautious of potential scams on the Internet. Crooks might try to swindle money from you by offering fake antivirus tools that look precisely like legitimate software.[2] Therefore, download the free malware removal tools listed below only from official websites or authorized distributors.

1. BitDefender Antivirus Free offers award-winning protection that does not use a lot of computer resources

BitDefender Antivirus employs an innovative technology called behavioral detection[3]. It closely monitors apps that are present on the computer and checks for any suspicious activity. If the free malware removal tool detects any programs acting out of the ordinary, it takes immediate action.

The free antivirus protects computers from Trojans, worms, ransomware, spyware, rootkits, and even zero-day exploits. Thus, it definitely gives real-time protection from every possible cyber threat that is lurking on the web.

Bitdefender also has a paid version that offers more features and an advanced level of protection. However, if you are not willing to spend any money, you should install a free version of a security program. The free antivirus is compatible with:

• Windows 10, 8.1, 8, or 7 SP1

2. Malwarebytes Anti-Malware Free cleans different kinds of threats from affected machines

Malwarebytes is considered one of the best malware and spyware removers. While you can become the user of its Premium version offers an efficient anti-malware program for free. The products of this company detect and eliminate more than 15 million threats every day. This virus removal tool provides real-time protection and automatically identifies new and old computer hazards to protect your system before malware infects your PC[4].

Malwarebytes Anti-Malware software offers an anti-exploit function alongside the common anti-ransomware. The combination of these features guarantees that ransomware attacks will be stopped before corrupting your data and vulnerable systems will be shielded from the exploit strike. However, this feature is available only for paid version users.

Fortunately, there are free versions for both Mac, Windows, Android, and Chrome OS users. Likewise, you can enjoy a safe computer despite the operating system you use. Additionally, there is a variant for Android fans to protect their devices and privacy as well. The free version of anti-malware offers these features:

• Anti-malware and anti-spyware – detects and removes cyber threats from the affected device;
• Anti-rootkit – locates and deletes rootkits and repairs files that were damaged;
• Blocks scam calls (only Android version);
• Provides a safe browsing feature.

Thus, this free tool is great for cleaning the affected machine. However, if you want to keep antivirus features for longer than a 14-day period, you will need to pay for the license. Note that the premium version of Malwarebytes Anti-malware tool costs $39.99 for one machine.

3. Kaspersky Free Antivirus is basic protection for Windows computers

Kaspersky Free Antivirus provides the core protection for Windows operating systems. It can spot the most popular threats, malicious websites, and similar issues that have already become common among the Internet community. You can download this program from its official website which also provides links to Kaspersky Internet Security, Kaspersky Total Security, Kaspersky Security Cloud, and others.

Kaspersky Free Antivirus is compatible with these operating systems:

• Windows 10,
• Windows 8.1,
• Windows 8,
• Windows 7

The Free Kaspersky Antivirus is completely free of charge and simple to use. Once you run the full system scan, it delivers an informative scan report informing about the outcome — whether the malware was detected or terminated. Likewise, people, who do not have lots of expectations for their anti-virus will be able to enjoy its protection level.

However, if you keep important files on your computer, like visiting dangerous sites, or performing similar activities, you should think about upgrading. While the program provides real-time protection, blocks malicious websites, and disables dangerous files, it doesn't offer protection against malicious attacks, improve your privacy, etc.

If you are interested in these activities, think about Kaspersky Internet Security which will cost you $59.95. (1 device a year, prices may differ because of the region)

4. AVG AntiVirus Free offers real-time protection

AVG is a well-known security software developer which was acquired by Avast in 2016. After joining their forces, these two antivirus vendors have accumulated an impressive number of users worldwide.

The most known products of AVG are AVG Antivirus, AVG Ultimate, and AVG Internet Security. However, the company has also been offering a free version. No matter that it can be obtained without a fee, it is considered a reliable malware remover. In fact, it has been approved to be the best free malware removal tool.

The main feature offered by AVG free is the protection against malicious downloads that are removed before they get into the system. If they happen to find their way to the computer, you can also stay relaxed because every file is prevented from launching at first. The program analyzes every new component and wipes if it finds the file to be malicious.

Besides, the great news is that you can get real-time security updates when opting for AVG free. With their help, you can be sure that your computer is protected against the newest malware, such as ransomware, spyware, and other cyber threats that keep emerging every single day.

Antivirus also blocks unsafe links, downloads, and malicious email attachments. Thus, this tool helps to minimize the risk of phishing attacks. However, independent test results show that the anti-phishing feature is not as good as other security programs.

Finally, users are also available to try the AVG Web TuneUp plug-in that they can add to their browsers to make their browsing on the Internet more secure.

An excellent choice. But don't just take my word for it. Go ahead and give the program a try. (source: PCMag)

According to the program's developers, you will be more than satisfied with its new and simple design which explicitly shows how you are protected from malware attacks. Additionally, AVG Antivirus tool does not slow down your computer. If you would be interested in extending its features, you can get the full protection for $70 a year.

• Windows (10, 8, 7);
• Mac OS X (OSX 10.8 Mountain Lion or above);
• Android OS (2.2 or above).

5. Panda Free Antivirus tool offers free help only for one month

Panda Antivirus software is categorized as one of the best free malware removal tools since it requires no supervision — once installed, it does all the job for you. Also, it is great that it functions in the cloud[5]. Therefore, you don't need to store files or perform regular updates.

What is more, Panda Antivirus ensures safe online browsing and shopping. Likewise, you are protected from e-shop scams and other phishing attempts. The premium version is compatible with Windows and Android devices which allows you to enjoy several more features like an anti-theft alarm, lock and wipe function, and real-time location for your gadgets.

One of the most significant features is Panda's USB drive vaccination. Thus, it scans drives for malware and does not let malicious programs to the computer. Indeed, it's a unique feature that might give an extra layer of protection if you frequently plug in external drives to your computer.

However, the antivirus does not provide as good protection as other free security programs. The program did not give great results in independent testing and our tests.
