I might not be super intelligent when it comes to the malware and virus world, but I am aware enough to not open anything, to go to the http:// site and find out if an offered download really came from them, am aware to not click open emails, but, alas, this computer is shared by my husband, who is a complete turkey! He just says..."Oops", and calls me...! "The computer quit working"... or, "I am getting these porno pop-ups somehow"... like on my LAST computer! That computer, by the way, is still sitting on my floor: it has our wedding photos in it, and I am unsure if I can get them out, without bringing in a virus, or attack of whatever it was that killed it... it is still running, but ..'retired' until I find out if I can get photos safely out.
A behavior blocker for my husband, or grand kids would be worth it's weight in gold!
