To make it short: CPU - Pentium133; RAM - 24 Mb; HDD - 1.5 Gb; FDD - 3.5". The man said he couldn’t buy new hardware (it’s not private) and asked me to find a reliable on-demand antivirus scaner to check floppies and CDs.
I tried DrWeb-CureIt: it works but takes 3-4 minutes to start and be ready to check floppies.
I don’t know of any modern on-demand scanner that would run with these minimum specifications, the crippler probably being 24MB RAM. I’m surprised DrWeb’s CureIt did.
Add to that it is probably running running an old Operating System (?) which will also rule out many of the on-demand scanners.
I believe The old legacy version of Command will. However they are not updating the Engine anymore, only database updates and no tech support. And even the legacy version is $39.95 a year
So, avast or F-Prot for DOS will do it.
Also, there are tools for automatic download of F-Prot updates in the web.
avast for DOS will work great and the virus database is closer to the Windows version.
