I have Windows XP, and when I sign on, the screen is blank. Ctrl+Alt+Delete works, so through the task manager I am able to run programs. I read previous posts from users with the same problem, and saw that I could regain my Desktop by running Explorer.exe. This will work for a few seconds, and then it will all be gone again, and then come back a few seconds later. I can open my programs and the internet and everything, but every few seconds the start menu and desktop icons disappear. I have run my spysweeper, and I removed every thing it found. My virus software (Trend Micro Antivirus) didn't find anything, and I saw that experts suggested to run SDFix for people with my same problem, so I did that. Reading the advice for the forums I realize I probably shouldn't have done that, but it found a Trojan and removed it. However, the problem is still here. I would greatly appreciate help. Thanks.

Let's try this

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:[list]
  • Update Malwarebytes' Anti-Malware
  • Do Not Launch Malwarebytes' Anti-Malware
Then click Finish.

If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Run Malwarebytes

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. Reboot your computer into normal mode if possible.

If normal mode works, rerun Malwarebytes in normal mode. Please scan with the settings as above. Be sure you post both logs.

So far everything has been working smoothly. Is there anything else I should do?
Thanks again!

Vundo H is a very hard infection to clear... Let's continue with SDFix.

Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.
