I still have this problem even with the latest updates (I’ll have to give you the numbers later today). I’m using WinXP SP1 and Outlook SP1. I’ve tried manual update without Internet Explorer (6.0) open. THe update is completed then after a short time of using IE the computer slowly locks up and I can’t do anything apart from hard reset. Even Ctrl-Alt-Del doesn’t work. Please can you give me a solution, or I will have to go back to aVast 3.0. Thanks
