When these messages about site safety pop up, PLEASE do NOT click on any message there may be about looking into a computer protection program. I did that one time several years ago and they downloaded a huge trojan, which crashed my computer. Fortunately, Geek Squad was able to recover most of it, but the HD was so heavily infected, they said they'd never seen one that bad. Kaspersky keeps out these intruders... I recommend it highly. If you get these pop-up messages often, I'd go into Security and set the security level higher, so they can't get in.
