Microsoft Defender vs Surfshark Antivirus

Microsoft Defender and Surfshark Antivirus compared side by side: protection, performance, pricing, and features. Which antivirus suits you better?

Microsoft
Microsoft Defender

Microsoft Defender comes pre-installed on every Windows PC and provides solid baseline protection against malware, phishing, and ransomware. In independent tests, Defender now performs well and is often sufficient for users with cautious browsing habits. However, anyone who needs VPN, password manager, extended web protection, or parental controls should consider a paid suite. As a free reference point, Defender is the most important comparison benchmark.

Surfshark
Surfshark Antivirus

Surfshark Antivirus is part of the Surfshark One suite, combining virus protection with VPN, data breach alerts, and a private search engine. The antivirus detects malware in real time and protects your webcam from unauthorized access. The biggest advantage: unlimited devices at the same price. Ideal for families and shared households looking for an all-in-one security package at a top price. Pure antivirus protection is solid but not quite at the level of Bitdefender or Norton.
