Hi all,

My desktop (Win XP pro, SP 3) recently seemed to have some big issues. One day after using some programs and having the browser open for sometime, it froze. I had to restart many times and it kept happening. Then I started an AV scan with Trend Micro. The scan gets stuck at one particular time (some file that was created before this happened with I compiled some VC++ program). So, I thought that file might be infected and I cut and pasted that file elsewhere. Then again the scan get stuck at another file in the same directory. If I kept the scan on for some more time the computer again froze. When I try to scan for spyware etc. using Ad-Aware or Spybot the computer again froze. So, I restarted the computer in Safe mode and did the virus scan, but the same result. I also tried to scan using AVG scanner (of course uninstalling Trend Micro), but for the same outcome.

After reading in some forums, I found few external AV scanning programs like Clamwin, McAfee stinger. Clamwin finally found one Trojan userinit. The log for Clamwin is attached. But it seemed like it didn't remove the file since, I could see it. Then I found that it is a system process, so I also scanned using ComboFix if it might restore the file. The log of ComboFix is attached. I could not make any head or tails of it. But again I didn't find any mention of userinit.exe. Can somebody please look at these log files and let me know what the status of my comp is.

Note: If I do not open the browser or use an AV scanner to scan files in the safe mode, the computer did not freeze.

Please help me asap, I really need this computer to be fixed.

Thanks a ton

Please note the message text in blue at the top of the Am I infected? What do I do? forum.

ComboFix logs should not to be posted outside the HijackThis forums and then only when requested by a HJT Team member. It is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

Please create a new topic explaining the nature of your problem in the Am I infected? What do I do? forum. Describe pop-ups and system tray or desktop icons that have appeared. Explain what is "going wrong" with your computer. Note any tools you have used and their respective results.

If needed, we will direct you to our HJT Preparation Guide.
