I ran quick scan as you said and got log and I translated there some english so you could understand what it says .. I tried to change programs language to english but apparently my computer skills weren't high enough It found only that Trojan.Agent.Gen and "deleted" it.. After reboot Malwarebytes Anti-Malware put instantly "Trojan.Agent.Gen" and "Trojan.Agent.cn" to quarantine. MBAM-log-2013-03-02 (16-25-08).txt

It says that "Nothing was done" Well I don't know about that one because I bought my computer from friend who bought new computer for himself. Could this be a problem? I've had this computer like 6 months now and didn't have any problems untill now.

Ok, I ran that scan and found the same svchost trojan agent. posted log there, however it's written as finland for some reason. MBAM-log-2013-03-01 (18-48-48).txt

Here's the new logs! mbar-log-2013-03-01 (17-03-09).txt system-log.txt

Ok I ran Combofix and it rebooted my computer, on start it said something about registrys and "svc" something and my computer started normally as it used to start. But nothing else didn't work then so I restarted my computer and it started slowly again with that svchost taking 25% of my resources. Should I've done something before restarting my computer? Got log. ComboFix.txt

Scan is complete, There wasn't option to "cure" there was only something about quarantine so i didn't know should I take it so i choosed to skip, got log. TDSSKiller.2.8.16.0_26.02.2013_22.12.11_log.txt

I did many system scans and everytime it gives same.. If i run scan after scan without reboot it doesn't find anything anymore, but when i reboot it always come back. I also turned my antivirus off because it was blocking something from registry but it didn't help anything. There's logs attached. system-log.txt mbar-log-2013-02-26 (20-54-20).txt

I finished scan and have result for you! RKreport1_S_02262013_02d1700.txt

Hello, my computer has been infected by Trojan:W32/Agent. I have ran security check with advanced system care 6 and it found Trojan.Agent in svchost.exe... (my avira antivir doesn't detect that)... ASC will delete virus every time, but it's always back on reboot and it takes 25% of my resources so it slows down my computer. I really don't know what to do and i would be so glad if u helped me I attached "dds" and "attach" dds.txt attach.txt
