I remember about a decade ago, there was this real fear of virus, spyware, hackers and scary people on the Internet who go around hacking into users system with the authorities were trying very hard to catch up with hackers. Thus we spent most of our time trying to prevent that. Then came Zone Alarm, the free firewall for people with no or very little computer experience. It was just wonderful. Gave us a peace of mind when we are on the Internet. I love the way that little meter keeps monitoring your Internet connection for any suspicious data. Of course, now we do have many options from other developers but I still like them. Anyway, they have expanded to a complete Internet Security suite - antivirus, firewall, browser security, antispyware, ID theft prevention and so on.
