    Lab Test Showdown

    Trend Micro Maximum Security lab results: 16.5/18 at AV-TEST February 2026. Approved Windows Security Product at AV-Comparatives 2025 Summary Report.

    Avast Free Antivirus lab results: 18/18 at AV-TEST February 2026. Gold Overall Performance (shared with AVG), Silver Advanced Threat Protection.

    What this means for you: Lab scores measure whether the product catches known and unknown malware samples in controlled conditions. Both Trend Micro Maximum Security 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

    Trend Micro Maximum Security: $39.95 first year, $89.95 at auto-renewal. Family-focused parental controls + Pay Guard; 4.7/5 Gartner 1,834 reviews

    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.
