hi everyone.

just recently i ran into a problem with popups galore, even though my blocker is on, etc, etc.

avg free 7.5 can't find an infection, ccleaner removed all it could do and ad aware has done the same (x3 for both). still i have this incredibly intrusive problem though. the popups begin as soon as i open my home page (sympatico/msn) - some of them about playing a 'think you know it all' (or something close to that) game and some of them "free scans" if there's something wrong with your computer. ive never clicked on any of these to be taken to their sites and i know better than to download things from partner sites or anywhere im unfamiliar with.

the file is called A00FA8D3B and its listed in my temporary files in the startup registry as _A00FA8D3B.exe (as reported by ccleaner)

i cant find anything on google, castle cops, here or anywhere for that matter. ive tried substituting the "00" part of the title as the letter o and/or the number zero with all combinations just in case i wasnt seeing it properly - but still nothing.

thanks in advance for your suggestions.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.

If you’re clean, you should create a new Restore Point to prevent possible re-infection from an old one.

Go Start > Programs > Accessories > System Tools and click System Restore. Choose the radio button marked Create a Restore Point on the first screen then click Next. Give the Restore Point a name and then click Create. Then use Disk Cleanup to remove all but the most recently created Restore Point. Go Start > Run and type: "Cleanmgr" (without the quotes). Click Ok > More Options tab > Clean Up in the System Restore section to remove all previous restore points except the newly created one.
