The first virus was your standard fake Anti-Virus trojan horse. Easily defeated with Malwarebytes Anti-Malware and several reboots.
Quite by accident while I was checking to make sure that Firefox was updated and I noticed a weird thing with google ads within the pages. There was another virus that AntiVir and Malwarebytes Anti-Malware didn’t pick up.
What I was looking at was basically a google hijacker.
It was surprisingly difficult to figure out exactly what was going on. I had a pretty nice rootkit on my hands. As everyone knows, where there are rootkits, there is Combofix (http://www.bleepingcomputer.com/combofix/how-to-use-combofix note: combofix.org is a fake site).
I obviously did a hijackthis and a couple other scans and I’m pretty sure that the computer is clean. For now.
