i cant access any webpage with ie7, if i write any page at the adress
bar and press enter,  a windows popup called "address bar" that says
the page is unavaliable, like for example, ("http://www.google.com" is
currently unavaliable.) and if i click on any page from my favorites,
it just show a Blank page.

I was working fine a few weeks ago, and since i mainly use Firefox, i
dont know the exact moment it stop working, but since i havent install
anything new i cant narrow the problem.

i tried resetting ie7 options and deleting any temp file but noting
change.

I dont use firewall, not even the winxp one, my antivirus is avast (i
also tried IE after disable it but same)

I have also a few friends (2 to be exact) that i think have the same
problem, but since they live far and they aren't really good with
computer, i havent been able to confim this, they just told me
something among the lines of "My internet wasnt working, i couldnt go
to any page, so i call Brighthouse, the technician delete Internet
explorer and now im using mozilla"

I'm fearing that it was a "Windows update" that cause the problem, so
i will like some help figuring this out.

Thank you
