I'm running win2000, IE6.0.28 & Firefox.8 and avg6 virus software ( latest signatures), Zone alarm pro, Spybot S&D. On my automated daily scan on May 18th AVG detected Trojan.downloader.agent.Al in c:\winnt\system32\Winhost32.exe. It also found downloader.1stbar.3.BC in inst_install.exe and was unable to repair/heal it - I manually deleted it and it has not returned. In over 2 years of use this is the first time anything has gotten past AVG. AVG could not repair the Winhost32 file and could not quarantine it. I manually deleted the file. About 3/4 hours later AVG popped up and reported the trojan again. I repeated the scan and again manually deleted it as AVG could not. This has now been going on for 4 days. Attached is my Hijackthis log. Any ideas on how to remove this pesky @&^!$*?
