FAQ

Common questions

How were these rankings decided?

Each pick is drawn from our full lab-tested review set and ranked using the same protection-rate, performance-impact, and pricing data published on its individual review page.

How often is this shortlist updated?

We re-check rankings every test cycle — roughly every quarter, or sooner if a major vendor update changes detection or performance numbers.

Can I see the full ranking instead of just this shortlist?

Yes — the full lab ranking with filters for OS, price, and purpose is available on the Rating page.

Do these picks include paid placements?

No — rankings are based purely on lab data. Some outbound links are affiliate links; see our Disclosure page for details.
