To install ADD REMOVE PRO to sub for this while you look for other pests. Given the damage I see such do I never am assured that it can be fixed but at least we have a stand-in.
I am running WinXP-2. Sometime in the last 2 months? my 'add/remove program' program was lost. When I click on it the hourglass shows for a split second and nothing happens. I have tried a fix bat file solution, but that didn't work. I was advised to pick a restore point, but have no idea what point to restore. Could I have disabled the program? Could a registry cleaner have removed it...with my help, of course? Any ideas?
