RegASSASSIN is a free software that helps you in deleting the rogue registry keys that Malware might have placed on your system. Such registry keys are normally extremely difficult to delete. RegASSASSIN lets you delete such difficult to delete registry keys.
RegASSASSIN is a portable application. It works by resetting the permissions to registry key, and then it deletes the registry key. Just select the registry key that you want to delete, and RegASSASSIN will take care of the rest.
However, before you start using it, read this: RegASSASSIN does not tells you which registry keys you should delete. That is something you need to figure out yourself. If you do not know which registry keys to delete, don’t even try experimenting with this software; you might end up completely messing up your system. If you are not too sure, try to use Panda Safe CD, or Normal Malware Cleaner instead.
Even if you know what you are doing, it would be a good idea to backup registry before playing around with it. And once you have cleaned your computer, make sure you have a good anti malware on your system.
