Phony Activation Message?

Hello.  I have Norton AntiVirus 2005 and Norton Ghost.

 

Both products are up to date.

 

Today I got this weird activation message that said to the effect " the product has been disabled because you have not activated it.  Trial period over." Something like that.  I have had this product for at least nine months and I activated way back then.

 

It is NOT a message saying that the subscription ran out or anything like that.

 

This sounds fake to me.

 

Any thoughts?

 

Thanks.

 

Michael
