I recently have had my computer infected with a trojan/virus, and so far I have not determined exactly what the problem is or how to fix it. I found this forum after searching online for help, and it seems like such a great resource that I thought I had better give it a try :-)

This Tuesday (25th August 2009) I downloaded a file (computer game related). The file was a .cab program. Before running the program, I scanned the file using ClamWin Antivirus. Results indicated that no virus was found. I executed the program, and it appeared as though the program did not perform it's intended function; instead, a cmd window appeared and the hard drive started to be accessed heavily. I quickly closed the cmd window. I then opened Task Manager (note, I am using Vista Ultimate) to see what was going on - there seemed to be a lot of activity in the process list (processes started disappearing, in a seemingly unnatural way - or maybe I was just being dramatic hehe). I then shutdown windows, which seemed to take longer than usual (hard drive was still being used heavily). At this point, I suspected that my computer had been infected. In hindsight, I believe I should have extracted the .cab file (with 7zip) and scanned the contents directly.

I then disconnected my computer from the LAN and rebooted. After I logged in, I saw the following new links on the desktop: nudetube.com, pornotube.com and youporn.com. Now I really knew that my computer had been infected!!

After this, I tried a number of tactics to fix the situation, including:
- submitting the downloaded file (and its contents) to www.threatexpert.com
- scanning the downloaded file (and contents) on another machine that has Norton Internet Security installed; it found viruses, although did not provide a lot of information about them (links to virus descriptions only gave general information)
- scanning my machine using linux live CDs with anti virus programs on them (tried clam, avira, f-prot, bitdefender; each giving different results, some indicating no viruses were found on my machine)
- removing the new links on the desktop and other suspect files via linux live CD boot (using the "find" program to attempt to locate files that were recently modified)
- rebooting to Vista and running SpybotSD

After the above, I performed another scan of the machine (linux live CD to boot, f-prot anti-virus to scan). Indicated that there were no viruses (although a couple of other warnings which seemed harmless).

I performed another reboot, thinking that my problems were solved. Unfortunately, the links reappeared on the desktop; so I wasn't able to solve the problem.

That is when I did further research online, and came to this forum. I've carried out the instructions on the "Preparation Guide"; results follow.

I have attached the files: attach.txt from DDS and ark.txt from RootRepeal.

I have also attached the files: hijackthis.log from HijackThis, and mbam.txt from Malwarebytes' Anti-Malware.

I have allowed Malwarebytes' to "Remove Selected" malware that it found. Note, I have also run SmitfraudFix (did not save a log for this), and let it fix the items that it found.

Appreciate any help.

Oops! After running mbam, and letting it fix the items it found, it indicated that a reboot was necessary. After reboot, I tried logging into Vista, but the following dialog box appeared:

"An unauthorized change was made to Windows"
"Windows has discovered a change that will result in limited Windows functionality. Use the link below to find out how to fix Windows"
(then there is a link "Learn more online", and a link "Close").

Clicking "Learn more online" brought up another dialog box (note, the machine is not connected to the internet):

"An unauthorized change was made to Windows"
"You will no longer receive notifications, including those about your license or activation. Use the link below to find out how to fix your system."

This dialog has a button to "See details", which when clicked displays:

"Error: 0xC004D401"
"The security processor reported a system file mismatch error."

Seems that there is now no way for me to log into Windows.

Any suggestions?

Hello again.

I have decided to perform a reformat and reinstall; so, no need to attempt to remove the trojan. If anyone knows which trojan it was, I'd still be curious to know what it was.

Also, I wanted to ask: I have 2 additional hard drives on my machine, could the trojan have infected these drives also? They are both ntfs, and are used generally for backups.

Thank you for letting us know. Sometimes the best and quickest solution is to reformat and reinstall.

I have 2 additional hard drives on my machine, could the trojan have infected these drives also? They are both ntfs, and are used generally for backups.

That possibility exists. I'd suggest posting in the Am I Infected forum to receive further assistance regarding this question.

This topic shall now be closed. In case you experience any problems with the computer, please start a new topic.

Happy computing,
