explorer not responding

Greetings!

I have been having problems with my browser. I open up a browser window and after a short time of working in the window it stops responding and then I go into task manager to find out what happened and I find that my process is not responding,. I close that one and then open another window and then the same thing over and over again. I’m not quite sure how to fix this.

Also my system performance is very slow. Does anybody know of a checklist of things I can check or do to try to improve my performance.

I’m also using my ags antivirus and for some reason the anti-virus hangs every time I try to run it.

Thanks so much for any ideas you may have.

Rick
