Greetings , This site has helped me many times in the past, thank you. Now it's my turn to contribute. This is my first post so please be patient.
My computer ended up with a problem this morning. A fake scan kept starting named "AntiVira AV" and could not be stopped, the more I tried the faster the pop ups became and eventually the program locked me out completely and Xp crashed. I could not start any programs period. Could not connect to internet period. Could start firefox in safe mode and found proxy settings had been altered, reset to default but still not able to connect. Tried several scanners ie: avast boot time scan, spybot, malwarebytes, combofix ect. Avast found no problems, and no other scanners would run. Googled AniVira AV and tried several of the cures posted to no avail. While looking at running processes with Lasso I noticed a strange entry named fywrxtpsikk.exe, when terminated forcibly the scans stopped and I was able to run malwarebytes and found and repaired the malware,Attached File  MWBytes_screen.jpg   99.66KB   4 downloads screen shot follows as attachment. The following is the log:

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

Please take note:

  • If you have since resolved the original problem you were having, we would appreciate you letting us know.
  • If you are unable to create a log because your computer cannot start up successfully please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.
  • Please tell us if you have your original Windows CD/DVD available.
  • If you are unable to perform the steps we have recommended please try one more time and if unsuccessful alert us of such and we will design an alternate means of obtaining the necessary information.
  • 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.
  • Use the 'Add Reply' and add the new log to this thread.

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation 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.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE

We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice

Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log

Thanks and again sorry for the delay.
