Since the end of last week my computer has been acting like it has a virus. It started with error messages about my anti-virus software not being able to update. When I tried to go to the AV site it would tell me that my network connection was down. I could not go to any AV sites (AVG, Symantec, Lavasoft, etc...) all of them came back with errors. I could get to other sites like Google and ESPN but not AV sites. When I ran my anti virus software it came back with nothing found. But it usually finds cookies and small things so I knew something was up. So I booted my computer in safe mode and ran the Microsoft Malicious Software Removal Tool and it found 3 major threats, then I ran AVG and it found some more. Then I ran Ad Aware and cleaned up all my temp files. I brought my computer back up to regular mode and I can now get to the AV sites and my AV software can update but I get these random alerts from my AV software saying that different Trojans are being found. One of the ones that came up talked about a Trojan Horse Downloader.Generic.7.BDNN The process name it had listed was C:/windows/system32/svchost.exe. I ran HJT and will post the log in the next message, can someone help me?
