This virus(?) will lock up my computer at odd times, won't let me on, or just won't boot. I have wiped disc (formatted) many times and each time it will unpack itself as soon as I get OS running(XP). Someone told me that it sounds like it is in the BIOS. I tried to do a bios flash and update the bios, but it would not let me do that, locked me out and shut the computer down.
