advertisement webpage comes out automatically. espacailly in these days, very very often. once i open a new ie window, there r alway 2 -3 come out! why? and what should i do ?

popping up ... or get some web browser that has some simple built-in ad page block functions.

any websites that pop up more than 1 ad page, I don't visit any more..

可能你以前浏览某个网页的时候被改了Registry
