Windows Enterprise Defender is a rogue anti-spyware, or scareware, program from the Virus Doctor family. When installed, this program will be configured to start automatically when you load Windows as well as making a series of harmless files with the following names:

%UserProfile%\Recent\cb.sys
%UserProfile%\Recent\ddv.dll
%UserProfile%\Recent\eb.sys
%UserProfile%\Recent\energy.exe
%UserProfile%\Recent\pal.sys
%UserProfile%\Recent\PE.drv
%UserProfile%\Recent\ppal.exe
%UserProfile%\Recent\tempdoc.tmp

When Windows Enterprise Defender scans your computer, it will detect the above files as infections and state that you need to purchase the program before it will remove them. The reality is that these files are all harmless and can have no effect on your computer. They are only being created, and then detected, to scare you into thinking you have actual infections on your computer. As you can see this is a scam and you should not purchase the program for any reason.

While Windows Enterprise Defender is running it will display security alerts on your desktop stating that your computer is under attack or that active malware has been detected. These alerts are just another tactic where they are trying to convince you that your computer has a problem and should be ignored. As you can see, Windows Enterprise Defender purposely uses fake alerts and false scan results as a method to scare you into purchasing the software. It goes without saying that you should not do so, and if you already have we suggest you contact your credit card company to dispute the charges. If you are infected with this malware, then please use the guide below to remove it from your computer.

    Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.

  9. When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.


    MalwareBytes Scan Results


    You should now click on the Remove Selected button to remove all the listed malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.

  10. You can now exit the MBAM program.

Your computer should now be free of the Windows Enterprise Defender program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.

If you are still having problems with your computer after completing these instructions, then please follow the steps outlined in the topic linked below:
