If you are using Symantec/Norton AntiVirus, try disabling the
Office Plugin that comes with it (but don't disable Norton
AutoProtect). See http://support.microsoft.com/?kbid=329820 "How
to use Office programs with the Norton AntiVirus Office plug-in"
for more information.

Something happened to Norton today that has now locked me out of ALL my 2007
beta created documents, not just Excel.

I am told that all the documents are infected with a virus that NAV can not
fix and I can not force the documents to open.

I have run the repair and made sure NAV is up to date without curing the
problem.

Does anyone have a solution?

Thanks in advance,
