I am using windows XP and after the lattest updates, version 21.5.0.19, both internet explorer and Firefox now hang. They use about 98% of the CPU and I have to kill them using Task Manager. The strange thing with Firefox is that if I restart it
immediately after I have killed firefox.exe then it will start up normally. But after I close it down and try it again it hangs. I have restored my computer to a date prior to the update and all is fine, if I then let Norton update I am back to the same problem.
