I am very anal about what i look at on my computer. I have also 'trained' my 15 yr old to be the same way. She's pretty good about it, however i think she may have strayed a bit. I've been getting something like pop ups, but they take up the entire screen, basically opening a new window each time. i have a pop up blocker installed through my google tool bar. i went into my tools and cleared out which pop ups were supposed to be allowed (basically there's nothing there) i have Firefox, and have never had a problem, until today. anyone have any ideas what this is,and how i stop it? i dont have MacAfee, i have AVG virus protector. HELP?!
