These are NOT full anti virus software programs, but these programs are so small they easily fit on a floppy disk or USB stick they only cover a very limited virus definition range, and should only be considered as limited tools,

This is a tiny program, that searchers for and kills, the top 40 viruses only, but it easily fits on a standard floppy disk ( this is Addware annoying popup windows will appear until you restart your computer)

This program successfully detected and killed, a 2 day old major virus I'd placed on my desktop, wonderful

another tiny program that easily fits on a floppy disk, although it failed to detect and kill a 2 day old major virus on my desktop, its virus definition range didn't cover the virus I had, but with these types of program, it could have easily been the other way round
