I deleted norton virus since my account already expired. So I borrowed my brother's Mcafee and installed it to my computer. I tried getting on the Internet but when I do the page connection says cannot be connected. So I checked the signal strength and it says " very good" but it's still not connected? I share a router that is located in my sister's room which is like 10 ft away, and her computer is working just fine with the Internet. But I can't get on because it says " enter http in the address". I try to diganose and repair it say "no problems detected"... I don't understand what can be blocking me from the Internet. Oh ya d the firewalls are not up and I have windows vista. Can somebody help me please? Thanks! unlock iphone 3g
