I think I might be infected with virus or something alike.
I'm using Avira antivirus program, win7 enterprise.
Avira was alerting me about stopping some virus and after scan it apparently removes it. Thou that happened few times.
After that I got suspicious and looked at task manager and found some weird named processes.
Since Avira said everything is fine I tried malwarebytes quick scan and it returned with some random Trojan (that it removed and it never reappears on other quick scans )syshost (google search says it supposed to be a virus) and kmservice (google on later one confirmed it to be ms office crack, so its ok).
Malwarebytes did try to remove syshost but apparently Avira prevented it on pc restart, so now its in quarantine, but I think that the virus got back since it wasn't removed from registry.
So all in all help me to determine if im infected or not.
