ESET NOD32 Security
The fastest file-copy and app-launch benchmark times of any Windows suite we tested this cycle.
Bitdefender Total Security
The best combined protection-and-performance score we measured, with the lowest false-positive rate.

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.
