I don't have any pop-ups, so I must have done something right in the past (even if it was by mistake! lol). I use IE, I'm extremely wary of trying any other browsers as something always seems to go wrong every time I try and download/install anything new, which then panics the life out of me because I never know what's gone wrong or how to get out of it. All this cookies stuff confuses the hell out of my little blonde cells, so I think I'll just continue bumbling along in my blissfully unaware way, and trust that my AV stuff is doing it's job. I do actually do fairly regular scans and the AV has only rarely shown a virus, which it then swiftly deals with (thankfully, all by itself without me having to do anything). The one thing I am sufficiently on the ball about is regularly re-checking my privacy and account settings on Facebook, which I use quite a lot. Facebook have a habit of moving the goal posts, changing their (and your!) settings and introducing new stuff, all without publicizing it and thus without your knowledge. So I try to remember to check it all weekly. I also rarely (if ever) click on anything on there if I don't know what it is, even if it's something that a friend has introduced, as stuff on there frequently contains viruses.
