I initially posted on Am I infected and received direction to complete steps 6 - 9 which I have completed those that ran. I initially ws unable to run GMER but after getting errors as decribed below, it seemed to have run log attached. DDS on the other hand continues to display the error mentioned below. Thanks for your guidance

P.S. The Gmer log did not attach as it states it is too big to load .. 20,000 KB's in looking at it, it has evry file scanned. I also found an entry in a clamscan log that states /hda1/WINDOWS/BDOSCAN8/bdcore.dll: Trojan.Generic.FakeAV.WKA Found.. hope all this helps.

Also downloaded WD Diagnostics ran the extended test successfully.

I was surfing when this software indicated there were threats on my PC. My AV (Avira) popped up and I directed to delete (i beleive). In any case it continued to come up and my AV no longer alerted me which I then noticed it had actually shut down. I tried ending some processes that looked odd in hopes the icon on my system tray would go away indicating I had stopped it. Without success I decided to reboot and see what happened. Unfortunately I got BSOD with the following:

Aproblem has been detected and windows has been shut down...

If this is first time reboot, If appears again do following: check for virus, remove hdd, etc... Run chkdsk /f then restart...

Tech info
Stop: 0x0000007b (0xF78a6640, 0xC0000034, 0x00000000, 0x00000000).

I tried booting up with Hiren's Boot CD ((Mini Windows Xp) and from that it seems the HDD is operating and not dead. I can get into files and save those I think are important. I have run KAV from this (without new definitions) and it came up empty, could not run MBAM as an error (runtime error 5003) would pop up and it would not proceed. I really don't know what I am doing with this CD and am actually afraid of messing with MBR or other utilities for fear of making matters worse. I can not boot up in safe mode, last known config or anything else for that matter.

I am running Win xp sp3 ... I am desparately in need to getting my system up somehow but dont know what to do in view of not being able to get windows going... I have spent the last 4 hours reading but am not confident enough to do anything without some guidance. HELP HELP HELP HELP

Runing Wix Xp Sp3 ..

Just ran SuperAntispyware within Hiren's CD Boot and found some issues but while the program says they are being removed after reboot and rescan they are still there:

Looks like you have found a rootkit.. to prp[erly remove this and any more can you do this.

Please go here....

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.

No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review your topic an do their best to resolve your issues.

If you have already posted a DDS log, please do so again, as your situation may have changed.

Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
