If you use Windows 11 and want to spend nothing, Microsoft Defender Antivirus is already built in and covers the basics. For a paid suite, Bitdefender Total Security protects five Windows, Mac, Android and iOS devices for $59.99 in the first year, and you can try it for 30 days without a card. F-Secure Total costs more at first but renews at the same price, and Malwarebytes is the free tool to reach for when a PC is already infected.
