Lab Test Showdown
Malwarebytes Premium lab results: Not submitted (AVLab tested) at AV-TEST February 2026. AVLab Cybersecurity Foundation Product of the Year 2026; SE Labs AAA 2024-2025 at AV-Comparatives 2025 Summary Report.

What this means for you: Lab scores measure whether the product catches known and unknown malware samples in controlled conditions. Both Malwarebytes Premium and Avast Free Antivirus sit within the range where detection isn't typically the deciding factor — your pick usually comes down to pricing model, bundle features, and whether the corporate ownership matches your trust threshold.
Pricing & Renewal Reality
Malwarebytes Premium: $44.99 first year, $69.99 at auto-renewal. Cleanup engine + rollback; safely layers with Defender/Bitdefender/Norton
Avast Free Antivirus: $0 (free) first year, Free / $31.20 Premium Security at auto-renewal. 18/18 for free; Gold Overall Performance
The honest playbook for both products: cancel auto-renew immediately after purchase. Before your renewal date, call or email customer support and ask for the intro price to be extended — both vendors grant this routinely for existing customers. Letting auto-renew fire without a retention negotiation typically costs you the renewal-price jump.
