Adware, malware and viruses are EVERYWHERE, not just with pictures. Just clicking on a link will dump crap in. This IS a Monster, all this stuff BUT SpyBot gets out what it can, which is quite a bit, but on your very next site, pictures or not, more stuff gets in. Sometimes I will run SpyBot more than once a day. Once in a while or once a week just doesn't cut it. We are under attack constantly.

I also have Norton which runs automaticly once a day. IF something gets in you can always go to your ADD/REMOVE in your Control Panel. Familiarize yourself with what SHOULD be there and REMOVE any NEW programs that LOOK like Advertising. I will post some of them when I come across them.
