DOS antivius?

Hello everyone,
Does anyone knows where to download an AV for DOS. One of the HD is suffering from w32.weird. I can load win9x and install norton2000 it finds the virus claims it cleaned it I check again and it does the same thing. I used to have a floppy which just check the command.com on the blank drive. I don't know what happened to it, if I remember correctly it was from Fprot. Let me know if have anyother ideas. Thanx.

F-Prot DOS Antivirus is avasilable here f-prot.com or here bootdisk.com
Heres Nortons solution for you which uses their own av software.
