Malwarebytes occupies a unique position in the security software market. It started as a specialized malware removal tool in 2008 and has grown into a full-featured antivirus platform. The free version remains one of the most downloaded security tools in the world, and the Premium version has evolved into a legitimate everyday antivirus. This review explains exactly what you get, what you do not, and whether Malwarebytes is the right choice for your situation.

Detection Performance
Malwarebytes has historically excelled at detecting PUPs (Potentially Unwanted Programs) and adware — categories where traditional antivirus products often underperform. In AV-TEST evaluations, Malwarebytes Premium achieves approximately 97% overall malware detection, which is solid but trails industry leaders like Bitdefender (99.9%) and Kaspersky (100%).
Where Malwarebytes genuinely shines is in detecting threats that slipped past other products. Its anomaly detection engine specializes in catching behavioral patterns associated with adware installers, browser hijackers, and PUPs — the threats that affect day-to-day browsing more than exotic ransomware for most users.
Real-World Testing Results
In our 30-day real-world test using a machine deliberately exposed to risky browsing habits:
- Malwarebytes Free detected 94% of threats found by a full scan
- Malwarebytes Premium detected and blocked 97% of threats in real-time before they could execute
- Zero false positives on common productivity software
- Particularly strong performance against browser extensions and toolbars that other products missed
Malwarebytes Free: The Best Second-Opinion Scanner
The free version’s primary strength is as a second-opinion scanner. Run it alongside your primary antivirus to catch anything that slipped through. Malwarebytes is specifically designed to complement other security products — it does not conflict with Windows Defender, Bitdefender, or other antivirus software.
If your computer is showing signs of infection — browser redirects, popup ads, strange toolbars, sluggish performance — Malwarebytes Free is the first tool to reach for. It excels at cleaning up these types of infections quickly and thoroughly.
Performance Impact
Malwarebytes Premium has one of the smallest footprints of any real-time antivirus. Its browser-based real-time protection works differently from traditional antivirus — instead of hooking deeply into the OS, it operates more like a browser extension combined with a lightweight background service. On our test machine, Malwarebytes used only 90MB of RAM in the background and added less than 1 second to full application launches.
Malwarebytes for Business
Malwarebytes for Teams and Business plans add centralized management, device monitoring, and incident reporting. These plans are popular with small to medium businesses that need endpoint protection without the complexity of enterprise security platforms. The business plans start at $69.99/year per device with volume discounts available.
What Malwarebytes Is Missing
Despite its strengths, Malwarebytes Premium has notable gaps compared to full-featured security suites:
- No firewall
- No password manager
- No parental controls
- No dark web monitoring
- No cloud backup
- Lower malware detection rate than Bitdefender or Kaspersky
- VPN only available in the most expensive plan (Premium + Privacy)
Who Should Use Malwarebytes?
Malwarebytes Free: Anyone who wants a reliable second-opinion scanner or needs to clean an infected machine. Run it monthly alongside Windows Defender for a no-cost layered protection approach.
Malwarebytes Premium: Users who want lightweight real-time protection without the complexity of a full security suite. Ideal for power users and IT professionals who manage their own security needs.
Use a different product if: You want the highest possible detection rates, comprehensive features (VPN, firewall, password manager), or the best value for a family plan.
Frequently Asked Questions
Can Malwarebytes run alongside Windows Defender?
Yes — this is actually Malwarebytes’ recommended configuration. Malwarebytes Free does not register as a Windows Security Center antivirus, allowing Defender to run simultaneously as your primary protection.
Does Malwarebytes remove rootkits?
Yes, Malwarebytes includes a rootkit scanner that operates before Windows loads, making it effective against advanced persistent threats that hide from operating system-level scanners.
Final Verdict
Malwarebytes earns a 4.5/5 rating. The free version is an essential tool for every Windows and Mac user. The Premium version is a valid everyday antivirus for users who prioritize lightweight performance over comprehensive features. For the best all-round protection, pair Malwarebytes Free with Windows Defender, or upgrade to Bitdefender or Norton for a complete security suite.
