I suspect I got infected with some kind of keylogging or trojan software. It appears that my e-mail acconut has been hijacked

I have got any idea how this happened as I'm sharing this computer with my roommate, his e-mail account has been hijacked too.. found out that the malware could be hiding in drivers directory, few av scans showed *.sys files with different names infected in there, tried to remove it unsuccessfully - every next scan comes up with another filename.sys
I would appreciate some help with this issue, got no idea what to do :/
logs incoming

Gmer crashed during the scan and refuses to start..
