I start up my computer today and a whole bunch of regestry edits come up in ad-aware. I don't know why so I deny all the changes. Now just about every program on my computer wont work. Just about all my icons are gone and are just the little page with the foolded corner. Every time I try to open a program I get a message that says:Windows cannot open this file. Then gives me the options to go online to find the appropriated program to open it which it never does. The file extensions whenever I try to open something is .lnk. I am running XP pro sp2. Oh, I also can't even open system restore, that was the first thing I tried. Firefox is working though. Need quick help please. All help is greatly appreciated.
