I'm posting here cause I'm really desperate. I have been suffering with some rootkit for some month now and I'm suspecting a SMM rootkit.
I have previously received help here on the Virus, Trojan, Spyware, and Malware Removal Logs section in two threads.
Two Malware Response Instructors who first examined my FRST logs, couldn't find evidence of active malware on my computer.
The first build had MSI G45 Gaming Z87 motherboard and got infected. I ended up buying a Gigabyte Z97X Gaming 3 and got infected again by mistake.
I have tried Windows 7 x64, Windows 8.1 x64 and Windows 10 pro x64 all bought and legit, but it still seems like my OS is being fiddle with.
When I bought the Gigabyte motherboard I reused all same hardware such as CPU, GFX, HDD, SSD, RAM and DVD-drive and were clean until I made a mistake with the wrong USB-drive.
I'm quite convinced that something has been messed with on the motherboard and I have looked into chipsec (http://www.intelsecurity.com/advanced-threat-research/chipsec.html)
I have tried to fuzz SMM and found a bad SMI handler, but I'm clueless how to fix it. Here is a screenshot taken from chipsec (http://imgur.com/4PFHIcn)
