Do you know that the primary function for any virus attack is to disable the registry editor i.e. Regedit.exe. Thus preventing you or any application to further modifying the system settings. Though there are many tools available few of which i have already mentioned previously but all of those were on how you can fix that problem. But in case none of any method have worked then what to do?
Then the best solution would be to use an alternative which is RegAlyzer which is almost same as windows registry editor.
So if you want to download and use it then let me tell you that this application doesn’t require any installation and free to use. Just download it run the standalone application.
