What Operating System do you use? If i remember correctly, that virus only infects/work under windows95. So if you have Win98/ME/Nt it could be possible that you are not able to start again. If you use still FAT/FAT32 Bootpartition you can boot to dos(or use a bootdisk) and replace the infected files with the orginals or use a DOS Scanner. If you have NTFS Partitions you can ask for Avasts Bart CD!:wink: Does Avast still have a Version for Dos?
Otherwise you can try F-prot/DOS from ftp://ftp.f-prot.com/pub/f-prot.zip
