The Best Free Malware Removal Tools of 2026

The best free malware removal tools don’t just prevent threats. They can help detect and remove active infections already on your device. We evaluated each malware removal tool using real-world detection tests, performance impact measurements, and hands-on usability reviews and found that Avast's free tier is best overall for removing malware.

Bitdefender Antivirus Free is one of our recommended products for Windows and Android users, specifically because it includes options like Autopilot, which scans your mobile device for Android threats. If you're looking for alternatives, TotalAV is chock-full of features like real-time protection, defense against phishing, and performance optimization tools.

And if you'd rather not stack up several free tools to cover everything, Avira Free Security bundles the widest set of extras we found on a free plan — a software updater, a password manager, a browser extension that blocks phishing pages, and PC cleanup tools all come with the free download.

We’ll explore the specifics of the best malware removal tools so you can get the protection you need, whether you have an infection now or want to guard against a future threat.

Avast Free Antivirus: Best overall

What we liked

Real-time protection: There’s a lot to like about the free malware removal tool Avast offers, like real-time protection. This feature works in the background while you work and isn’t noticeable, so you can get on with what you need to do. We also found that Avast doesn’t cause performance issues, which sometimes happens with antivirus software.

Network protection: In addition to protecting against viruses, adware, spyware, Trojans, and other malware, Avast Free Antivirus scans websites to keep you safe from malware threats and to secure your online credentials. The network inspection tool will check any new networks you access for security vulnerabilities. You get Wi-Fi network security plus real-time phishing protection.

What we didn’t like

No firewall for Mac: Avast's firewall is available only for Windows, so if you use a Mac, you’ll have to rely on Apple's built-in firewall.

Paid upgrades: Although we think the Stay Safe Virus Guarantee is a great feature to include, we don’t think you should have to auto-renew to get it. With that feature, if you auto-renew your plan, Avast refunds your money in the event you contract a virus the software cannot remove or fix. This guarantee shouldn’t worry you, though, since Avast has excellent malware detection rates.

Bitdefender Antivirus Free: Best for Windows and Android

What we liked

Ease of use: Bitdefender Antivirus Free is easy to install and launch without any fuss. It takes mere minutes, and you’re ready to start using Bitdefender. You also get anti-fraud technology, SafePay, and a VPN to help keep you safe from online scammers.

Security: The free plan protects against the all-too-familiar rootkits, Trojans, and ransomware, as well as newer types of threats like cryptojacking and AI-powered phishing attacks. This is key since malware is ever-evolving and even a free anti-malware tool needs to keep up in order to protect your devices.

Upgrades available: Like most antivirus programs, Bitdefender’s paid versions offer more features, such as Network Threat Prevention, Rescue Environment, and a secure VPN.

What we didn’t like

Lackluster Mac performance: Bitdefender may be the best antivirus software for Windows, but if you use a Mac, you’ll need to get the free Virus Scanner for Mac from the App Store.

Although we’re accustomed to most antivirus products catering more to Windows users, it’s disappointing when so many features aren’t available for macOS. As the name suggests, the Virus Scanner for Mac tool focuses primarily on scanning your device. Even so, we aren’t sure why Bitdefender left out scheduled scanning and a file shredder for macOS.

Extra steps: We also didn’t like that Bitdefender comes in two parts. You have the antivirus app and the Bitdefender Central browser hub. You must be logged into the browser hub to set up parental controls, and we found that extra step made the whole process less user-friendly.

TotalAV Free: Best value

What we liked

Extras: As antivirus software goes, we were happy that TotalAV Antivirus Free was easy to use and provided a no-nonsense way to have more online security. It includes the necessities like spyware, adware, and ransomware protection, but the real magic lies in the extras you get with TotalAV’s free plan.

The data breach scanner alerts you if your email or passwords are compromised. This gives you a heads-up to change your login info before it’s too late. We also like the Advanced WebShield feature, which protects you against malicious websites that try to steal your info or infect your device with malware.

Additionally, you’ll get optimization and privacy tools like the tracking cookie remover and browser cleaner.

Paid upgrades: With TotalAV’s paid plans, you get options like phishing protection, a VPN, and TotalAV’s ad blocker, Total Adblock. You can even view your hard drive summary with the Disk Usage Results feature.

What we didn’t like

Buggy: We had a few issues with the main dashboard. When returning there after using some of the features, we received a notification that the protection was disabled. Even after enabling the software again, we were instructed to go through the same steps to give TotalAV full disk access. The repetitive process was a bit annoying, to say the least.

Confusing labels: TotalAV doesn’t seem to make a clear distinction between the WebShield feature and real-time protection. That can become confusing when navigating through the software options.

Avira Free Security: Best free feature set

What we liked

The most tools in a free download: Most free antivirus plans give you a scanner and little else. Avira Free Security — the same app Avira used to call Free Antivirus — packs in real-time malware protection, a software updater that patches third-party apps, a password manager, an ad and tracker blocker, Avira Phantom VPN, and the Avira Browser Safety extension, which stops phishing pages from loading. That's a lot to get without entering a card number.

Cleanup tools that come free: Avira also includes PC cleanup on the free plan. It finds and deletes duplicate files and junk data to reclaim storage, and trims what loads at startup so your computer boots faster. If a malware infection has left your machine sluggish, having removal and cleanup in the same app saves you from installing a second tool.

Smart Scan: Avira's one-click Smart Scan took about a minute in our testing and sorted what it found into three buckets — Security, Privacy, and Performance. Anything safe got a checkmark, anything risky got a red minus sign. Selecting Fix issues resolved them without us having to work out which setting to change.

What we didn’t like

Heavier on system resources: Avira had the largest performance impact of any tool on this list. AV-Comparatives scored it 23.0 in its September 2025 performance test, placing it 14th — well behind McAfee's best-in-test 2.6. If you're running an older or lower-powered machine, one of our lighter picks may suit you better.

Weaker on Mac: Avira's Windows and Android apps test well, but macOS is its soft spot. It earned 15.5/18 for protection in AV-TEST's macOS evaluation, detecting 97.5% of samples against a 100% industry average, and there's no Avira firewall for Mac at all. 

No support on the free plan: Phone and email support are reserved for paying subscribers. On the free plan, you get the knowledge base and nothing more, which is a real gap if you're mid-infection and stuck.

Honorable mentions

Sometimes the best free malware removal tool for one person may not be the best one for you. If that's the case, check out some of our other tested products that we liked:

• McAfee: McAfee offers a premium security suite with different plans to fit almost any budget. While its Malware Cleaner tool is free (and also difficult to find — you’ll need to download it from the help article), you can also get a 30-day trial of McAfee Total Protection, which includes coverage for unlimited devices and a VPN.

How free malware removal tools work

Free malware removal tools are designed to detect and remove malicious software that may already be present on your device, including spyware, adware, trojans, worms, and some forms of ransomware. These tools scan your system for known malware signatures and suspicious behavior, then attempt to quarantine or delete infected files.

This sets it apart from antivirus software, which is primarily focused on prevention. Traditional antivirus tools monitor your device in real time to block malware before it installs, while malware removal tools emphasize identifying and cleaning up threats after an infection has occurred. Many modern security programs combine both functions, but the balance between prevention and removal varies by product, especially on free plans.

Some free antivirus programs offer limited malware removal and focus more heavily on detection, alerting you to threats without fully removing them unless you upgrade. The free malware removal tools on this list all provide legitimate removal capabilities, making them suitable for users who suspect an active infection or want basic cleanup protection at no cost. However, advanced threats, deeply embedded malware, or repeat infections may still require a paid upgrade for complete remediation and system repair.

Bottom line: The best malware removal tools

We chose Avast as the best free malware removal tool. In addition to its excellent protection scores, Avast includes a network scanner that checks your Wi-Fi and alerts you if it finds security vulnerabilities.

Bitdefender is a strong option for free malware removal on Windows and Android, while TotalAV offers added value through device cleanup and privacy tools. Avira is worth a look if you want the most features bundled into one free download, as long as you don't mind a heavier hit to system performance.

Finding the right malware removal tool doesn’t have to be a major headache. We’ve dug through dozens of antivirus solutions to find the ones that protect you from multiple types of malware and also offer advanced features — on top of offering a free download.
