I upgraded to IE7, removed some of the toolbar icons to de-clutter the interface, and made sure the phishing filter was turned off. Despite all that, I'm still using Firefox mainly because in everyday use it seems much lighter.
And it is also the most unsecure IE there is, because it contains many unpatched security vulnerabilities and it is flawed by design, though it is supported till 2014.
Hass anyone found that IE7 saves web information in a hidden location in your registry that is not removed by deleting history, cookies, and files. IE6 seems to delete everything when you ask it to. Very annoying feature when using IE7 on either a XP system or windows 7 system
