I am working on a friend's computer, Dell Inspiron Mini running WIN XP Home SP3. No Anti Virus software installed but it does appear to have most of the required updates.

I got the unit with a complaint there was pop up fake antivirus program that locked up the PC. It was registered in the Control Panel and was removed through the Add/Remove programs. They dont remember exactly what it was.

Here is what I see. Everything seemed normal at first. I loaded all the windows updaate needed, no problem. I loaded the Windows security tools, it started to run once and will not start. I get several re-directs when surfing for Anti Malware software. Cannot run any of my standard tools.

Spybot installs, runs but terminates
Malwarebytes installs, runs but terminates at about 9 seconds, unable to run again without reinstalation.
Hijack runs and terminates.

I have tried each of these with alternate names and extensions (.scr or .com) Nothing seems to run.

I have been through the running processes and don't see anything obvious. I've looked up everything running and again nothing obivious (I'm guessing it's named to look like a valid process.)

I picked up a copy of Rkill. It ran but nothing chnaged in the symptoms. I do have one clue. I used a removable drive to install the tools on the Dell Mini. After working last night I plugged the same drive into my laptop and my Antivirus Software picked up on an infection on the Drive (Bloodhound.expolit343)

Scan type: Auto-Protect Scan
Event: Risk Found!
Security risk detected: Bloodhound.Exploit.343
File: E:\1F6D0078.lnk
Location: E:

User:
Action taken: Pending Side Effects Analysis : Access denied
Date found: Saturday, January 22, 2011 8:03:25 AM

Any help would be great.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MR Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
The power of accurate observation is commonly called cynicism by those who haven't got it.
