NIS 2009 Locks Up My Taskbar

I have had Norton Internet Security since 2000 and have never had any real problems until this version.

I installed nis 2009 on three computer and all of them are having the same issue. When you start up the computer and press any of the quick launch buttons the computer will freeze and act like it is trying to do something but even after hours of waiting nothing happens. There were some websites stating that the bho add in (in internet explorer) was the cause but I disabled and still have the same problem. I have to restart the computers 2-3 times to get it to actually function properly. PLEASE HELP !!!

 

Thanks
