Sometimes when i'm surfing i'll get a pop-up ad that can't be dislpayed, but before i can close it, it repoduces itself and in a few seconds there's around 50. This happens really often and it's starting to be a huge p***off. I've noticed sometimes it's ads from doubleclick but others will do it also...

get a popup killer

Go on Google and look for PopKill...Works great for me! You can adjust the size of the pop-ups you wanna block and you can choose to block full-screen pop-ups. I usually set it to 1023x767. So anything under that resolution will be killed!
