not being able to open programs

alrigt my problem is really weird. It is probably really easy to solve but unfortunately i ave not been able t find a patch or delete the virus if tere is one. All te programs on my computer are working but it is impossible for me to open anyting directly i.e. I cant open Microsoft Word but i can open a office file tat I wrote before and then i am able to use word. Oter ting arent tat easy though. For example tere is no way to open Outlook Express like tat and its a pain in the butt to check every email adress by itself. Internet Eplorer also just opens over te link on the desktop not wit te lionk in te start bar. It is a really weird problem to have so could someone please elp me


oh and to add.. the problem is only concerning .exe and I have deleted every virus tere was.. Dont tell me to use system restore cause it runs on an exe.. terefore it wont work

 

Try command prompt and type sfc /scannow (note space) and put in xp disc. If that doesn't work try a repair http://www.uea.ac.uk/itcs/software/xp/xprepair.html

and the 'h' on your keyboard isn't working...
