1. Introduction
As cyberthreats evolve, so must your defenses. In 2025, antivirus software does far more than scan for viruses, it protects against ransomware, phishing, zero-day exploits, and privacy invasions across Windows, macOS, Android, and iOS. We’ve aggregated independent lab results, hands-on tests, feature breakdowns, and value analyses to bring you the definitive guide to the best antivirus software this year.
2. How We Chose Our Top Antivirus Solutions?
We considered four core criteria:
1. Malware Detection & Removal
– Scores from AV-Comparatives, SE Labs, and MRG-Effitas.
2. Feature Set
– Firewalls, VPNs, password managers, ransomware shields, parental controls.
3. Performance Impact
– Boot-to-scan times, resource usage during full/system scans.
