This problem (as so many seem to) appears to have come out of nowhere, although I suspect (for no particularly solid reasons) that it could be something to do with the security tools which I have installed - Norton AntiVirus 2005, Webroot Spy Sweeper, Webroot Windows Washer and ADSGone 2004 pop-up blocker. Is it common/likely that security tools or their settings may cause slow opening of IE?
Or could it be something to do with my ADSL connection (which hasn't exactly been trouble free), but, usually connection problems still allow you to open IE, just not to view any sites.
Any help greatly appreciated.
