Anti-Virus Utilities

Unlike other software at DOS Days, you probably shouldn't opt for older versions of anti-virus software unless you're on this page purely for nostalgic reasons, as they won't contain the very latest updates. Whilst its highly unlikely any viruses that run in DOS have been written since the late 90s, it makes sense to 'boilerplate' and get the one with the most up-to-date virus definitions.

My recommendation for higher-spec DOS PCs is Kaspersky Antivirus 32. This DOS version is no longer supported but Kaspersky Labs kept the same mechanism for updating its daily virus definition files (in daily-downloadable ZIP files) right up to late 2009, though I only have a working set up to 2002 which works on the version 3.0 found here. The last of their cumulative virus definitions ZIP file is present if you wish to try and get it working. You will need an 80386 or higher processor and at least 180 MB of free disk space.

For older, slower DOS PCs, F-PROT is my recommendation - it has the latest virus definitions file from 2009, runs on any DOS PC, and requires only 17 MB of free disk space.
