How to remove Windows Protection Suite (Uninstall instructions)

Windows Protection Suite is a fresh rogue antispyware program from Virus Doctor rogue family (Windows System Suite, Windows Security Suite, Malware Destructor 2009, etc ). During installation, Windows Protection Suite configures itself to run automatically every time, when you boot your computer. The fake antispyware also changes your HOSTS file and drops a few files, that during the scan will determine as infections. But these files are actually harmless.

Immediately after launch, Windows Protection Suite will begin to scan your computer and list a large amount of infections. All of these infections are fake, so you can safely ignore them. It uses false scan results as a method of scaring you into buying the software!

  6. Found the issue with taskmgr and any spybot/adaware/AV software not running…..

    Regedit for key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options. Browse for any stuff that is not working. (The key path may not be 100% correct, but the last bit is ‘Image File Execution Options’. This allows to attach a debugger to a program to trouble shoot by redirecting the execution to a ‘debugger’ before the process starts.). I found my Taskmgr.ext being redirected to svchost.exe. This would cause it not to launch at all. EXPORT YOUR KEYS BEFORE DOING THE FOLLOWING!!!! Remove the key then test to see if it works. If it does not work, import (or merge) the key back to the registry!

    I removed the taskmgr key from the Image File Execution Options (which pointed taskmgr to svchost.exe) and task manager came up with no issues!
