Windows Security review What to look for in an antivirus suite Nonetheless, it’s a free program that already comes pre-installed in most Windows machines and it does a good job of keeping you protected from most threats.

Windows Security also has ransomware protection, which many free options don’t. If Windows is already working, why add anything else?
