Malwarebytes Alternatives (2026): 10 Malware Removal Tools

Malwarebytes is famous for cleaning up infected computers, and lots of people keep it around as a second opinion. But there are other good scanners and suites, depending on whether you need a clean-up or ongoing protection.

Here are ten Malwarebytes alternatives in no particular order, sorted alphabetically, from free second-opinion scanners to full security suites. Each description comes from the vendor's own website, re-checked today. If an account rather than a computer was hit, my guide to recovering a hacked Instagram account covers that.

Decide what you need. If something's wrong today, a scanner helps clean it. If you want protection every day, a suite with real-time scanning is the better fit.

Then check your device. Some tools are Windows-only, and Mac users need tools built for macOS.

How Windows Defender reacts when you install another antivirus

Here's a detail that confuses people. Microsoft's own documentation says that on Windows devices not onboarded to Defender for Endpoint, Microsoft Defender Antivirus goes into disabled mode automatically when a non-Microsoft antivirus product is running.

So installing a full suite usually switches Defender's real-time protection off, which is normal. Don't run two real-time antivirus products together. A second-opinion scanner you run now and then is different, and that's where tools like these shine.

What to compare in malware protection

• Real-time protection: or on-demand scanning only.
• Platforms: Windows, Mac, Android or iPhone.
• Removal: how well it cleans existing infections.
• Weight: how much it slows your computer.
• Extras: web protection, firewall or family tools.

What to do if you think your computer's infected

1. Disconnect from the internet.
2. Run a scan with your installed antivirus.
3. Run a second-opinion scanner.
4. Change important passwords from a different, clean device.
5. Restore from backup if problems continue.

Which kind of malware tool suits you

If your computer's acting strangely today, a free second-opinion scanner is the quickest way to check and clean it.

If you want protection that runs all the time, a security suite with real-time scanning and web protection is the better choice.

And if you're on a Mac, choose tools built for macOS rather than Windows tools with a Mac badge.

Questions to ask before you install security software

Security tools run deep in your system, so choose carefully.

• Does it offer real-time protection or scans only?
• Which devices and systems does it cover?
• How will it affect my computer's speed?
• Will it switch off my built-in protection?
• Can I uninstall it cleanly later?

Malware clean-up mistakes to avoid

• Two real-time antivirus tools. They clash.
• Downloading 'cleaners' from pop-ups. They're often the problem.
• Changing passwords on an infected device. Use a clean one.
• No backups. Keep them current.

Fraud shows up in advertising too, and my look at mobile ad fraud shows how widespread it's become.

Do you make security tools? Tool makers can ask to be considered for a featured place on this list.

My plain advice on Malwarebytes alternatives

Keep one real-time antivirus and one occasional scanner. That pairing covers most people without slowing their computer.

And remember the basics. Updates, backups and careful clicking stop more trouble than any scanner can clean up.
