I'm having a bit of trouble with my laptop. I bought Norton Internet Security 2007 at the weekend and got round to installing it today. The installation went fine and the laptop restarted itself afterwards and then began to update the virus protection. It hung on installing new virus definitions for well over an hour, with no hdd activity, so I switched it off and then back on again. Now it does not get past the welcome screen. Does all the POST checks fine, does the XP Loading screen and then stops at the welcome screen. I have tried with both the Norton 2007 disc in and with it removed but it doesn't make a difference. Any Ideas?
