Anyone know a good place to get info on Spybot?

A friend downloaded soybot from (windows catalog?) I think that's where he said he got it anyway, I wasn't watching him run it so I really have no clue what happened. Alls I know is his primary drive isn't detected in the bios anymore, a blue screen at boot but it flashes so quick I can't read the damn error. So anyway I'm wondering if he'll need to purchase a third party application to fix the damn thang and if so any suggestions on which product he could use?

Thanks in advance,
TSB
