I'm running XP and have recently upgraded my Norton IS 2002 to 2005. What a fiasco! Two days and about five hours on the phone with Mahmoud and Achmed and it finally installed. Now I'm getting a new error about Microsoft IE that says "Your current security settings prohibit running ActiveX controls on this page. As a result, the page may not display correctly." This pops up every time I click on the Norton icon in the system tray. The Norton screen comes up with this error, and after I click the OK button on the error, the Norton screen sits there with "Refreshing" on it. It never gets any farther. I've tried going into IE security settings and clicking on Enable ActiveX controls and plug-ins, but that doesn't seem to help. I've got an e-mail into Symantec but they said I would get a reply in 4-5 business days. Needless to say, this is the last Symantec product I will ever own. The Apple Imac I've been looking at is looking better and better.
