Faster surfing with Windows Vista

I have changed my modem with HP sony ericsson modem, and instal driver to may windows vista and it's work and I think more faster than before, and better performance with internet explorer 7,
Another advantage internet explorer 7 is they have protected mode, Phishing Filter and we can control condition our computer if the icon phishing gren it mean safe, and if the colour red it mean the condition not safe to make any tansaction via internet if you using such as paypal or credit card
