I purchase their Regdefense registry cleaner software this morning and used it and it crashed my whole computer to the point of no return. System Restore wouldn't even work. It acted just like a virus by wiping out all windows programs by making them into shortcuts that lost their original programs. All DLL files were wiped out. Am very upset and when I tried to contact them they only had email access to leave them a message and that said I would have to wait up to 2 days for a response. BAD, BAD, BAD!!! read full review »
