I am hoping someone can help me with removing the cssrss.exe Trojan from my PC. I have windows XP home edition.

I was infected with the windows xp 2008 virus and finally was able to remove it all. However, I then find another Trojan called cssrss.exe, I have no idea if it is something different to the win xp2008 or if it is separate. I have ran scans, with AVG, Spybot search and destroy, windows defender, McAfee and Yahoo and still doesn't remove (Yahoo) or it doesn't get picked up by the others.

So I looked in the registry and did a search on all cssrss.exe and cssrss and deleted from there. The only problem is that it keeps saying it is in windows/system 32 but when I look there I cannot find the file to delete from my c drive (yes I also uncheck the boxes to show all hidden files). When I restart and do the same search it says it then located in windows/prefect, so I am able to find it and delete.
Again, on reboot I still find it running on my machine.

I am really at my end wits, no idea what else I can do to remove it. Can someone please help me?

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.
