Hello,

I would like confirmation that I have a rootkit/virus/trojan or not. I've run RootkitRevealer and it listed 177 instances of files with issues. Attempting to save the log caused it to crash before the log could be saved. I have not been able to run that app since.

As per http://www.bleepingcomputer.com/forums/topic34773.html I've run Defogger but it did not ask me to reboot so I don't think I have any CD emulation software. I then ran DDS and obtained the attached logs. I ran GMER and the machine rebooted. I ran GMER a 2nd time and the screen reset and came back blank. After powering off a external drive and then powercycling the machine, I tried to run GMER a 3rd time and lost the windows explorer. The log is attached.

The computer has been acting oddly in that the display freezes and either the computer reboots or the display comes back on with whatever I was looking at scrambled until I pass another window over it refresh it. No results page when windows reports the crash.

I am currently running AdAware along with AVG.

The OS is XP pro ver 2002 SP 3.


Thanks!

Hi, no rootkit activity so far! :)

COMBOFIX
---------------
Please download ComboFix from one of these locations:
Bleepingcomputer
ForoSpyware
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe and follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, or if you are running Vista, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image


Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

regards, Elise

The display still has issues. The system beep now keeps sounding even though I have the sound hardware working. If the system is clean, I'll focus on drivers or possibly a card went bad. Thank you very much for your help.

Verify if you have this problem also in safe mode. If not, it might be your display drivers. You can then try to uninstall/reinstall them.

If the problem persists in safe mode, you may have a hardware problem.

Did you try to reinstall these drivers and did that fix the problem?

Hi, I think the issue is hardware related. If I leave the computer off long enough for the display controller chip to cool down, I see no issues. But if I leave the computer on for a while (overnight or longer,) I see the problems with the window display. Some of the behavior reminds me of when the old RAMDACs in early 1990's would overheat.

Thanks again for your help, Elise! I'm going to hunt down a AGP video card to see if swapping it out helps.
