Outook 2003 slow responding

I have searched for an answer but I still am having problems with my Outlook and I am not sure what else to do.

The problem is that it is slow dang slow doing everything. If I clck on a msg, it's slow, changing folders it is slow and I often get Outlook not responding and I am going crazy. I have a program called ENDIT ALL and shut down everything and this has fixed the problem, but doesn't help knowing what was slowing it down.

My plugins are as follows.

1. AVAST
2. SPAM BULLY

I have had these in the past with no problems but how do I figure out what is interfering with it?

Thanks for the help and hope the following is helpful.
