Hello all, I hope you can help me with this issue. A couple of days ago while using Firefox my window was completely shut down and a grey pop-up box appeared alerting me to a potential virus:

hxxp://rootscan.info saying Warning! Your PC is at risk of virus and malware attack.
Your system requires immediate check!
System Security will perform a quick and free scan of your PC for viruses and malicious programs

I have heard of these fake malware alerts/pop-ups before, so I clicked on the X to close the box. Still, a new window opened which looked like a scan was starting. I immediately shut this down as well and ran all the anti-virus software I have on my computer: Ad-Aware, AVG-Anti-Virus, and Malwarebytes. Every scan came back clean. I shut down my computer and restarted it and everything seemed fine for a day. Alas, it happened again today.

I found a site that said this rogue anti-spyware application was called Virus Doctor and it gives instructions on how to remove it:


I followed the instructions, but every place I checked (in the registry and under Application Data) also came up clean. I don't think Virus Doctor ever downloaded, but I keep getting these pop-up messages. The pop-ups are annoying enough, but what I really hate is it completely shuts down the window I have open and I lose what I am working on.

Any ideas how to fix this? I look forward to your replies.

Kind regards, cheers,

Hello Virus Doctor is a Rogue applicatiion. In the future press CTRL+ALT+DEL keys to bring up the Task Manager. Then highlight the page "Virus doctor etc" and select the End Task button instead. This should prevent the Malware from execution. I am not to sure about the help page yet either.
This should work.

Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

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

alternate download link

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Scanning with MBAM in safe or normal mode will work but removal functions are not as powerful in safe mode. MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact, it loses some effectiveness for detection & removal when used in safe mode because the program includes a special driver which does not work in safe mode. Further, scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Doing a safe mode scan should only be done when a regular mode scan fails.

If you cannot use or complete a scan in normal mode, then try performing a Quick Scan in "Safe Mode". After reboot, click the Logs tab and copy/paste the contents of the new report in your next reply.
