Endless VirusScan Popup for __c0022F30.dat File

Hey folks...this has been driving me crazy for so long, and I just can't take it anymore. Very often when I kick off Internet Explorer V6, I get a McAffe virus scan popup for a file called __c0022F30.dat (those are two underscores at the front of the file name). A screenshot of the popup is attached. The file is located in c:\WINDOWS\system32. The popup comes up over and over and over again. I don't know what this file is, but I know that I can't delete it because it is always 'in use'. I logged on in Safe Mode thinking that I should be able to delete it then...I couldn't - it was still in use. I downloaded a utilitiy that identifies the files that running processes have their hooks into. Turns out this file is being used by winlogon.exe. And I can't stop that process.

Any idea what this file is?

Any idea if I can delete it? Do I really want to delete it?

Any recommendations? Thanks!

Please download Malwarebytes Anti-Malware and save it to your desktop.

• Make sure you are connected to the Internet.
• Double-click on mbam-setup.exe to install the application.
• When the installation begins, follow the prompts and do not make any changes to default settings.
• When installation has finished, make sure you leave both of these checked:
  • Update Malwarebytes' Anti-Malware
  • Launch Malwarebytes' Anti-Malware
• Then click Finish.
• MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
• On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
• If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
• The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
• When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
• Click OK to close the message box and continue with the removal process.
• Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
• Make sure that everything is checked, and click Remove Selected.
• When removal is completed, a log report will open in Notepad.
• The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
• Copy and paste the contents of that report in your next reply and exit MBAM.

Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

It worked! Thank you thank you thank you! Awesome tool!
