Can't download any new programs on XP

[cherylhicks]

I have searched and when it comes back with 18000 possible, it's mind boggling. I have windows XP pro, had a virus problem, got rid of it, but I think I lost a file or something. When I try and download or open some programs I get the pop-up box "what program would you like to use?" for example, I cannot open Firefox browser, I can't download IE 8, I can't open my Olympus Picture manager. I'm sure I am missing some sort of file. Any help would be appreciated.

I don't understand what you mean??? Do I type it in somewhere? I still need help.

In the Run box in the Start Menu, type in

sfc /scannow (with the space)

Then hit OK

The system will restore damaged files, and might ask you for your CD.
