Hey, guys. Upon start-up, AVG detects the following virus: Trojan horse BHO.KNI. I've also taken a screenshot of the Virus Vault ( http://i37.tinypic.com/2r3a7as.jpg ), which shows a few other threats. In addition, AVG has also detected a virus called Boha/Elsabah/Boh. I've done a Quick Scan with Malwarebytes' Anti-Malware, and it detected a few KeyLoggers which it seemed to have deleted successfully. Ideally I would like to avoid formatting, since all the re-downloading of Windows updates will nail my limited Internet usage. Creating an ISO of an Updated Windows also sounds troublesome. (: Helpful or not helpful, I'll also post a HijackThis log:
