Stop 0x00000050 Error

Hi, I must confess to not being extremely computer literate, so some advice on the following problem could prove useful.

Okay, first things first, I'm running Windows XP Pro. Earlier today my computer began to act rather erratically, MS Word was failing to save documents due to an 'infection' of some sort. I attempted to scan my computer for viruses, but I wasn't able to open Norton anti virus (It would open briefly and then disappear). So I then decided to scan for spyware using Ad-Aware (fully updated), It found a number of items which I duly quarantined. I then attempted another scan using Spyware S&D, which again I could not open. After restarting my computer I was presented with a dreaded blue screen, informing me of a Stop 0x00000050 Error: PAGE_FAULT_IN_NONPAGED_AREA, and therefore would close Windows.

So I restarted in safe mode to investigate. Ad-Aware found two critical items, a tracking cookie and a windows registry entry, the logfile of which is below:

Name:Windows
Category:Vulnerability
Object Type:RegData
Size:29 Bytes
Location:software\microsoft\windows nt\currentversion\winlogon "Shell" (explorer.exe winservnt32.exe)
Last Activity:28-08-2006
Relevance:Low
TAC index:3
Comment:Shell Possibly Compromised
Description:General Windows Security Issue. Your system security may be compromised. The specifics of the possible compromised item are listed in the comments section.


I then ran hijack this, which produced the following report:

I assume the problem lies in the winservnt32.exe file, although I am not sure by any means.

I apologise for such a lengthy post but would be grateful if anybody could take a look over the Hijack This log and suggest a possible solution to my problem, as I now cannot access Windows other than in safe mode. Oh, and I have also attempted a System Restore but that has not helped.

Any assistance at all would be grearly appreciated,
Many thanks,
Matt

Howdy mattboyslim,


Welcome to CTH. Can appreciate you finding some solution there, but one of your other startups showing is a Haxdoor rootkit variant (along with other infection there). If you would like, let's be about cleaning that system up.


Download haxfix.exe and save it to your desktop

* Double click on haxfix.exe to install haxfix. (standard installation path is c:\program Files\haxfix)
* Checkmark "Create a desktop icon"
* Click "Next"
* When the installation is completed, make sure that the checkmark "Launch HaxFix" is placed
* Click "Finish"

A red "dos window" (dos box) will open with options:
1. Make logfile
2. Run auto fix
3. Run manual fix
E. Exit Haxfix

* Select option 1. Make logfile by typing 1 and then pressing Enter
* Haxfix will start scanning the computer. When it is finished a logfile will open: haxlog.txt
* Copy the contents of that logfile and paste it into this thread > (c:\haxfix.txt)
