Malwarebytes vs Microsoft Defender
Not really rivals, whatever the forums say: one is the baseline shield built into Windows, the other is the cleanup specialist technicians reach for.
Malwarebytes Premium
The second opinion that usually has the final word.
Microsoft Defender
Already on your PC, and better than its reputation.
Our verdict
This is the rare comparison where the right answer is often both. Defender provides the always-on baseline with excellent lab scores at zero cost. Malwarebytes specializes in what slips past any baseline: adware, browser hijackers, and potentially unwanted programs, and its Premium tier is designed to run alongside Defender rather than replace it. Careful users can run Defender alone and keep the free Malwarebytes as an on-demand scanner. If you regularly rescue family PCs, Malwarebytes Premium next to Defender is the strongest budget setup we know.
“The cleanup champion. When something slips through, Malwarebytes is what technicians reach for, and it runs happily next to Defender or any suite. As your only protection it is thinner than the big suites; as a second layer it is the best money in this market.”Editorial team, on Malwarebytes Premium
“The free baseline that made half the paid market nervous. A perfect 6/6 protection score in recent AV-TEST rounds, zero nags, zero installs. It lacks a VPN, password manager, and cross-platform coverage, but for a careful single-PC user, Defender plus good habits is a legitimate choice.”Editorial team, on Microsoft Defender
