Best Antivirus & Malware 2026
Find antivirus and endpoint security software that protects computers and devices from malware, ransomware, phishing, and other threats. Modern endpoint security goes beyond signature-based virus detection to behavioral analysis and cloud-based threat intelligence. Compare detection rates from independent tests (AV-TEST, AV-Comparatives), performance impact, false positive rates, and additional features (firewall, VPN, identity monitoring).

Best Antivirus & Malware 2026 - Frequently Asked Questions
Do I need antivirus software on a Mac?▾
macOS includes XProtect and Gatekeeper as built-in malware protection — sufficient for most users who install software only from the App Store and trusted developers. Supplemental antivirus (Malwarebytes for Mac, free) adds additional detection for threats that bypass built-in protections. The Mac malware threat landscape is smaller than Windows but growing. Most Mac infections come from social engineering, not drive-by exploits — careful behavior matters more than software.
Is Windows Defender good enough?▾
Yes — Windows Defender (Microsoft Defender Antivirus) consistently scores in the top tier of independent antivirus tests (AV-TEST, AV-Comparatives) with 99%+ malware detection rates. For most home users, Windows Defender combined with safe browsing habits (email vigilance, avoiding cracked software) provides adequate protection without additional cost. Third-party antivirus adds marginal detection benefit but contributes system overhead.
What is ransomware and how do I protect against it?▾
Ransomware is malware that encrypts your files and demands payment for decryption. Protection layers: maintain current backups (offline/offsite — ransomware encrypts connected drives), keep software updated, use email filtering for malicious attachments, enable Windows Controlled Folder Access (blocks unauthorized file encryption), and avoid clicking links in unexpected emails. Backups are the only reliable recovery — paying ransoms funds criminal organizations and does not guarantee decryption.
