I just answered one of my own suggestions after I discovered the product comparison guide on the ZL website. It appears that ZL Antivirus is pretty close to ZA Pro minus all the spyware stuff I was referring to. So, I guess it qualifies as ZA Pro LITE. This is a much more palatable solution to a home network with lots of kids and cheap computers. We're not a business and it's pretty hard to consider buying 5 copies of everything with no quantity discounts nor up front permission to put one purchased package on three machines for home use....

Operating System:Windows 2000 Pro
Product Name:ZoneAlarm (Free)
