Best for cleaning already-infected computers
Visit Malwarebytes →Malwarebytes takes a fundamentally different approach from traditional antivirus software. Rather than leaning on signature-based detection, it focuses on behavioral analysis to identify and block suspicious activity. This makes it particularly effective against ransomware and zero-day exploits. Malwarebytes is famous for its cleanup tool, which has rescued millions of infected computers, but its premium real-time protection is equally capable as a standalone solution. In our tests, it caught 97.8% of malware with near-zero impact on system performance.
Machine learning-powered behavioral analysis that flags threats based on suspicious behavior patterns rather than known malware signatures.
Automatically creates protected backups of files the moment ransomware behavior is detected, allowing you to restore encrypted documents to their pre-attack state.
A free browser extension that blocks ads, trackers, scams, and phishing attempts. Works alongside Malwarebytes Premium or as a standalone tool.
Suppresses notifications and pauses resource-intensive operations whenever a full-screen application is detected. Ideal for gaming and presentations.

Yes. Malwarebytes Premium delivers real-time protection that can serve as your primary antivirus. It relies on behavioral analysis rather than traditional signatures, which means it also layers well on top of a signature-based antivirus if you prefer a defense-in-depth approach.
The free tier functions as an on-demand scanner only — it removes existing infections but does not block threats in real time. We recommend it as a second-opinion cleaner alongside a paid real-time antivirus, or as a cleanup tool for an already-infected machine.
No. In our testing, Malwarebytes had the lightest performance footprint of any antivirus we evaluated this year. Real-time protection produced no measurable drag on everyday tasks, and full scans used less than 5% CPU on a mid-range Windows laptop.
Yes. Malwarebytes is explicitly designed to coexist with other antivirus products without conflicts. Its behavioral detection engine complements signature-based products well, making it a popular choice as a secondary layer of defense.
Malwarebytes is the best pick for users who want lightweight, no-nonsense protection and for anyone dealing with an already-infected computer. The behavioral detection is excellent, and the negligible performance impact makes it ideal for older machines. While it lacks the bundled extras of full security suites, it excels at its core mission.
