I tried the basic Zone Alarm program but it didn't allow me to send any email over about one line long. I dumped it and got Norton's Firewall and it works fine. The Norton software was very busy blocking viruses and trojan horses until I put in the router for the wireless network. Now it quietly manages my cookies and blocks popup ads.

A web designer can set up a window that will launch and that contains no navigation tools at all. They can set them up so that the "X" in the corner doesn't work, or it does something else (takes you to a new more annoying screen). These windows usually launch from very aggressive sites that you reach by accident (often time a mis-typed URL will reach them--I was trying to reach abcnews.com and I may have left off the "s", but whatever, the resulting aggressive porn site was a shock.)
