I love any good alternative to mainstream overrated programs like Norton. In fact, if I didn't have so much time and effort loaded on my machine in a Microsoft Windows environment I would switch over to Linux.
Like I've mention before in other threads, I was using PC-Cillin with a year's subscription. It had everything like email scanning, firewall, script blocking, and so forth but it kept crashing my machine. I put up with this for a year and then started looking around. Tried one of your competitor's but thier email plugin would scan my entire inbox each time I opened my email client. I didn't like that. So I looked some more and found Avast. It has been working very well on my machine and would recommend it over any mainstream AV program out there.
You guys overseas are doing a great job here so keep it up. "When left alone the invisible hand of supply and demand will take care of itself." I see a wonderful future for Avast.
