Windows XP rundll32.exe problem

by Clive_w / April 8, 2011 6:01 PM PDT

Hi,

I have a laptop running windows XP and SP2. Looking around it appears to have a problem with rundll32. It can't find the application, however it is there on the machine.

XP came installed with the laptop so I don't have the original source CD, only recover CDs for reinstalling XP.

Due to not being able to launch any applications I can't get AVG running to perform a complete virus check.

Can anyone provide any assistance in how I can resolve the issue? I'd rather not perform a complete reinstall of XP if I can help it, but if it comes to that then so be it.

Many thanks.

Can you tell more about the error, such as:
- when does it come up?
- what is the exact error message?
- what is "there on the machine" and where is it?

Sorry, should have been more specific with my information.

I don't know exactly when it happened as a friend was borrowing the laptop at the time.

No actual error appears on boot up, it's merely that applications won't run. AVG is set to startup but doesn't - no error.

Having searched around the web a bit more I can across various threads about rundll32 virus. A lot of the symptoms I seem to have. If I right-click on the desktop (XP) it gives the error about rundll32.exe not being found.

The file is in c:\windows\system32.

Tried deleting it (to see what would happen) and when launching an app the file was re-created. Is this normal.

I cannot access regedit or be able to restore from a previous restore point as it keeps reporting the error about rundll32.exe not being found.

This has lead me to believe a full reinstall will be required, however would like to avoid that if at all possible.

Thanks.

Gave that a try. When running rkill it found a single malware process and killed it. Running the other full scans afterwards found a few trojans, which were removed, but that was all.

Perhaps I did it wrong but after running SuperAntispyware it said to reboot to remove the infections. Did this and upon bootup the same problem is occurring.

Out of curioisty I ran the whole process again and rkill found another single malware, this time in a different file.

Clearly I'm doing something wrong, though I believe I'm following the instructions given in that other thread correctly. Is it time to perform a reinstall?

Many thanks.

Now that rkill is finding this, I suggest a forum switch.

Name that pest and post a request for help in the Cnet Spyware forum.

The mods and members there are very good.
