Many times when working on a computer that has been infected with a malwar (virus, worm, trojan horse, spyware, etc), I find myself with the Task Manager, Command Prompt or Registry Editor being disabled. The malware creators usually do this to prevent the user from terminating or killing their process that is running on the system and to keep the user as far as possible from removing their nasty creations.
Of course there are many anti-malware that can remove the infection but most of the times there are minor issues usually left behind by the malware: disabled “Search” or “Run” button in Start menu or missing Folder Options in Windows Explorer. As a fix to quite a few common issues like is a tool called Quick Disaster Recovery.
Note: You can get it here.
Beside fixing those minor issues mentioned above, it can serve as a basic Task Manager replacement when the one incorporated in Windows is not be accessible. More then this, you can delete all the temporary internet files using this tool. This can be handy since the virus or malware files could be saved in the ‘Temporary Internet Files’ folder.
