word & excel very slow only direct opening

[mjjish]

This problem has been going on for about 2 weeks. Prior to that there was no
problem. When opening Word and Excel files from explorer it can take up to 30
or 40 seconds before the files open, but when files are opened directly from
within the apps then everything is fine. Other Office apps are OK,other app no problem,i tried norton,mcafee & kaspersky antivirus,lastly i got clue,network disable -perfectly alright ..whats problem ..pls help

I've seen a similar behavior before. This was caused by an update of Microsoft called " Office File Validation Add-In". Problem disappeared after uninstalling it.
