Hey guys. Infected with what Symantec is referring to as Trojan.FakeAV. Below is the information on the Symantec AntiVirus Notification:

Scan type: Auto-Protect Scan
Event: Security Risk Found!
Risk: Trojan.FakeAV
File: C:\WINDOWS\temp\expand32xp.dll
Location: Unknown Storage
Computer: CALIGULA
User: CALIGULA\SYSTEM
Action taken: Clean failed : Quarantine failed : Access denied
Date found: Sunday, August 15, 2010 9:39:02 AM

Symantec is intercepting a count of around 10 of these every 5 minutes or so. I'm standing tall to execute on a sanitizing strategy. Please let me know how best to proceed. As per always, I very much appreciate your assistance.

Thanks,
Caligula

I reinstalled MBAM, but it would not open in order to do a scan. I booted in safe mode and was able to get the MBAM updates and run the scan. I removed all the checked trojans it found, rebooted in regular mode and ran the scan again. It still found a few trojan items, and I had it clean those up too. Now, upon this reboot, I'm no longer getting all the trojan popups, but I can no longer connect to the internet. I get the message "Internet Explorer cannot display the webpage" and a button to "Diagnose Connection Problems". That utility tells me the that "Windows cannot connect to the Internet using HTTP, HTTPS, or FTP. This is probably caused by firewall settings on this computer. I know it's not my ISP, because I'm able to get on the internet with my other two pc's.

See if there are any bogus proxy settings configured:

Right-click the IE icon -> properties -> Connections -> LAN Settings. Uncheck everything in the proxy settings boxes.

They were checked, and turning them off has everything working again. I'll exercise it a bit more to ensure all signs of infection are gone and report back. Thanks, man!

I followed the instructions and everything seems to be running ok still. Here is the beginning of my Super log. There was a lot of adware cookies removed too, but no need for me to paste all that. Just let me know if you see anything here that warrants further action.

Thanks!
