Thanks for all the comments everyone!

edit: The reason I am still dubious about being clean is the time it takes for Win 7 to log me in (I have very little software installed after all the formatting), the time it lags when I click on my wireless connection, and I got an email yesterday saying one of my passwords for an account attempted to be changed. The laptop isn’t amazing or anything (i3-350m, 500GB WD Scorpio 7200rpm, nVidia 335m, 8gb DDR3), but it never ran this slow and I have it set to max performance and not max appearance.

It is a product from a very small company, which was a big mistake on my part and one I won’t repeat, as I am unable to update my BIOS and many drivers without specifically modding their .inf’s. When I run GPUZ/CPUID the fields for any pertinent mfg. data are not filled in. When googling the BIOS version I get one thread from another guy who bought the same laptop and he received no replies. The seller is really weird and uncooperative in providing me a copy of the BIOS. If it turns out this machine isn’t infected that would be great, but I have a weird feeling about it because the BIOS disables ATA Erase so my BCWipe can’t use that functionality.

After you check out the combofix log and deem my system healthy I’ll be less inclined to worry, but my desktop is also infected. aswMBR came back with a positive scan, and I ran the mbr fix. That didn’t really seem that great, and I’ll be wiping all the drives on that machine, and at least I can update the BIOS with the Sabertooth x58.

MBAM confirmed a lot of malware on this laptop prior to my formatting, and it was a redirect. After years of cautious behavior I fell out of the loop as to what commonly infects computers now and it’s made me feel like an idiot because I can’t effectively interpret what I see in any of these scans.

How prevalent are infections that make their way into BIOS/firmware?
