I did reply to your other post about getting into the BIOS, I suspect you just need to hit the right key for that Laptop to reach your BIOS. Since the BIOS is maintained on a chip on the motherboard is is extremely rare that it is involved with a virus, normally you could replace (or reformat) all the hard drives, install a fresh OS, and an infected computer is perfect again. The problem is, people usually want or need things off the old hard drives and then you risk re-contamination.
