I am currentl using IE7 as my internet browr and every now and then wn I switch to a new page i get a pop-up that opens full-screen in anoth IE7 window (ot a tab). This just started few days ago. I tried a systrestore before the problem was happening but that didn't work. I have tried running spybot SD, Ad-Awre SE, and norton full sytem scan multiple times. I ha updated all of them. Also I have been getting a of "trojan block, your system is secure" from norton. Could I have a trojan? Any ways to fix this problem?
