Back in 1993, Microsoft dropped its own antivirus—straight up called Microsoft Anti-Virus—as part of MS-DOS 6.0. This wasn’t some flashy standalone app; it was built right into DOS and co-developed with Central Point Software, who originally made the tool. It was basically a rebranded version of CPAV (Central Point Anti-Virus), with virus definitions updating through MSAV for basic boot sector and file scans. It got minor updates through DOS 6.2 and 6.22, but let’s be honest—it was super basic, even by ‘90s standards. No real-time protection, no internet scanning (because, well... the internet barely existed), but it gave users a little peace of mind at a time when floppy disks were the biggest threat vector.
