Norton AntiVirus Office plug-in has stopped working properly.

Yesterday MS Word stopped working.  When I send in the error message, I get this message back, "Norton AntiVirus Office plug-in has stopped working properly."

 

Over the past few days I have installed Opera as a browser, and I ran Ccleaner registry cleaner.

 

An hour ago I uninstalled MS Office 2003 and reinstalled it.  Same problem,.. MS Word just locks up.

 

I have Adaware, Malwarebytes, and Spybot installed also.  They have been on the computer for years, along with MS Office, and NIS with no problems.

 

MS Office automatic scan is selected off. 

 

How do I get MS Word to start working again?

 

Thanks for any help,

 

Bob
