Problems with several internet browsers?

I have a Compaq laptop.

Recently, I installed Norton antivirus software about a week ago. I noticed that my default browser (SBC Yahoo Browser) couldn't even start up.

I click on the icon, the window appears, but the users list does not show and the program immediately becomes "not responding" status.

Also, during Firefox and Internet Explorer browsing, about every 2-5 minutes or so, the browser temporarily becomes "not responding", taking at least 30 seconds to get back to normal.

Several times when I open up Norton, and I try to close it, the computer freezes and I have to force the computer to shut down (holding the power button for ~5secs).

Can anyone tell me how to get my computer and internet browsing back to normal, without the constant "not responding" appearances?
