Windows XP Professional SP 2 computer recently corrupted with a naughty bug which causes Google redirects, and multiple iexplore.exe processes. Changed the desktop wallpaper, which has been corrected after multiple scan attempts, but the IE connections and Google redirects persist. Prevents FireFox from running (uninstall/reinstall does not fix), and firefox.exe errors pop-up in windows dialogs even thought it has been uninstalled. Google Chrome works. IE will launch, but I'm afraid to surf.
This started with a fake security suite which AdAware and Malwarebytes were able to identify and remove parts. However, after the "cleanning" a Java 6 window opened and the fun really started.
The hosts file is clean, DHCP remains correct (auto), DNS is correct, and IE explorer does not show that a false proxy has not been set (no proxy is required for my network).
Things I have tried: (newest versions downloaded and updated just prior to use)
AdAware originally would run, and found a trojan (backdoor.TdServ) in sst90.sys and sst90.tmp. AdAware found nothing in the last 2 scans. But AAW will no longer function. I think the redirects allowed for the download of more nasties.
Hitman Pro 3.5 (build 118) is prevented from connecting to the internet to run (set to "no proxy").
Kaspersky online scan is prevented from functioning since it interrupts the internet connection.
Symantec Antivirus corporate that is up to date, but finds nothing.
Partizan from Greatis rootkit does not detect anything.
UnHackMe doesn't find anything.
Malwarebytes worked up until this infection, and will no longer complete its scan without encountering and error which forces it to close.
Emsisoft will install but will not run.
I don't see any random process names in the running process list. Upon restart, the Windows Task Manager shows 7 instances of svchost.exe, and I immediately gets windows error windows stating "Internet Exlporer has encountered a problem and needs to close" when the IE hasn't been started. (Perhaps iexplore.exe is needs for windows search, indexing and Groove?)
BTW, ComboFix had been used on this machine in August to successfully clean a rootkit bug.
I have followed the Preparation Guide on http://www.bleepingcomputer.com/forums/topic34773.html, started DeFogger, and ran DDS (logs attached).
GMER will not run to completion, but instead hangs after ~20 mins and requires a manual reboot.
I look forward to any insight and assistance your expertise may provide. I'm stuck! Thanks in advance.
