Explorer restarts when trying to open a CMD prompt 1

[ARIUK]

Hi,

PC running XP Pro, SP3 with all the latest patches. A/V is up to date, and also has ADawar installed. Every time I try to open a CMD prompt on the box, or run a script, Explorer restarts. I've also tried regedt32 and regedit and the same thing happens. HiJack this also fails to run, with the same issue.

I assume I have some sort of Trojan / Virus on the box, but Antivirus and Adaware both come up clean on a full scan.

Anyone had anything similar?

Try running an online virus scan using Trend Micro HouseCall and see if it finds anything.

Go to the Trend Micro website and download HiJackThis, run a log and paste it here for our discernment...

Why does Task Manager, MSCONFIG, or REGEDIT disappear while opening?

It sounds very like an issue we had recently with a bit of malware. The fixing steps are posted here:

Basically, a bit of malware got into the hklm\software\microsoft\windows NT\drivers32 section of the registry. Removing / correcting the key fixed things for us.

Wow! Thanks for all these responses.

Housecall failed to start a scan, with explorer crashing each time. Hijack this also did the same thing.

It was the same issue as in Magzy's post. There was a weird entry in drivers32 for the aux driver which pointed at a file in my "My documents" folder. Setting the entry back to wdmaud.drv and rebooting solved the problem.

Thanks again for all the assistance!

Great - glad it got fixed!
