When F-DRIVER.SYS is installed, it will detect the presence of the "Stoned" virus and lock up the system. This does not mean that your computer is ruined. I assume it is intended to *force* you to deal with the problem. The solution is simple. Boot from a clean floppy. Run F-DISINF and "cure" the hard disk. Reboot the computer normally. Simple. And effective. There was no need to reformat the disk. As to "prevention" of infection by a boot sector virus, that is not so simple. If you stick an infected disk into the A: drive and boot up, you are going to be infected before *anything* can come into play. The only solutions involve specialized boot ROMs, cards or mechanical disabling of the A: drive. ============== Vancouver p1@arkham.wimsey.bc.ca | "It says 'Hit any Institute for Robert_Slade@mtsg.sfu.ca | key to continue.'
