I have an XP laptop that was booting very slowly and applications would occasionally crash. I noticed that the "wpffontcache_0400.exe" process was consuming 75% of the CPU even when nothing was running. I went into services, and it was in the "starting" status. I eventually killed the process via task manager, then disabled it in Windows services. Eventually, directories started disappearing, etc.

Research said wpffontcache consuming cpu was a common virus symptom. I ran deep scan, and it said I had tons of registry errors, and the "backdoor.frauder" virus was detected. Further research suggested that it could be a false positive. I would like another opinion on how to proceed. I've attached a combofix log that I ran this morning

Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.

If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps.

Please download ComboFix from one of these locations:

Link 1
Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop

  • Disable your Anti-Virus and Anti-Spyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
  • Close any open browsers, and all other programs working. Make sure you save your file if working on a document.
  • Do not install any other programs until this if fixed.[/b]
  • Double click on ComboFix.exe & 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.
  • Some Rookit infection may damage your boot sector. The Windows Recovery Console may be needed to restore it. Do not bypass this installation. You may regret it.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

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

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.

Note: If you have difficulty properly disabling your protection programs, refer to this link --> http://www.bleepingcomputer.com/forums/topic114351.html

Do not mouse click ComboFix's window while it's running. That may cause it to stall

Third party programs if not up to date can be the cause of infiltration an infection.

Please run this security check for my review.

Download Security Check by screen317 from here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.
===

Please post the logs and let me know if the problem persists.

Post the logs for my review.
