Yellow Banner in WebTop and Documentum Administrator

I am sure many of you are familiar with the WebTop BHO and Native Client.  We have tried so many different approaches to minimizing the yellow banner but have determined that McAfee anti-virus is the main culprit.  Whenever Java initiates, something is happening with the rt.jar that fails the scan by McAfee which in turn causes us to receive the yellow banner. Everything is installed, enabled, Java is being correctly pointed to, etc. but this darn banner gets thrown in a lot of cases - not all cases.  If users open up another window or logout and log back in, then this typically resolves it but in some cases it doesn't.

Has anyone experienced anything like this?
