I got "sidefind" on my computer and when I tried to remove it with the add/delete function I ran into big trouble. First the add/delete box went blank and I couldn't bring it back up (access denied) same with any other folders. Then on startup I get a brown screen that says "unable to locate configuration files" the only option there is to click ok. It works for a while, brings up the wallpaper, then says "the program has performed an illegal function and will be closed." Then all I have is the wallpaper and an arrow I can move around. I have tried starting up in safe mode and it does the same thing. What do I do?
