That was one of the many problems I had last week .. I was ready to beat the heck out of my computer .. it all started with a thing called CleverIEhooker
As for Zone Alarm?? ... Their lastest upgrade I learned had problems and they will have a patch to fix it out sometime in July.
They had me un-intall ZA and install the last version I had ... which is 4.5 somthing and everything was back to normal with that part of my problem
How'd you know you had it?
