Lots of people don't realize the numerous ways we can help "the bad guys" infect our personal computers with bad stuff. Since we are webmasters, we should try to be as educated as possible about the tricks "the bad guys" use. I stumbled on this web blog that shows, via screen shots and clear explanations, how infections can get onto our PCs if we aren't aware of the bad guy's tricks. http://www.support.com/Community/blogs/ That site is a company but I am *not* suggesting anyone needs to use their services. But the Blog info is straightforward and seems accurate. I really appreciated the screen shots so I could look them over without any risk of "getting" a virus. Note the Blog Author cautions again and again to NOT try to reproduce the things he's showing and to NOT visit the sites he's showing. I also appreciated that he showed those pop-ups that say OK or Cancel & it's sometimes confusing about what action to take to avoid "getting" something nasty. He recommends shutting any open program and shutting down the PC and re-starting-- but how many of us try to just get the pop-up closed instead? The author explains that both options of OK or Cancel can still download an infection from those pop-ups. I hope the info helps someone. Judy
