On my home PC, my trial for Norton is up in a few days, which I really don't want to renew since I'm not insane about for most of the reasons already given. Doing my own comparison shopping, the thing that looked the best was the ZonePro Security system. I just wanted to hear anyone's opinion (good/bad/alternate brand suggestions) before I pulled the trigger on this and I wanted to ask this while I still have a few days left to decide.
I use Zone Alarm Pro, Pest Patrol and NAV 9.0 on all my computers--Dell Laptop, Dell PC, and an older gateway.
I have never used Norton's firewall programs but my Dells did come with all the MacAfee sofware--virus scan, firewall, etc. After about 3 weeks, I ditched all that for ZoneAlarm Pro.
One of the features I like best is that it asks questions about what kind of CPU you have, what kind of Internet connection and what your main uses of the CPU are.
After that--it self-configures and allows certain programs the amount of internet acess that can safely be given while still restirctign access to unknown programs and Internet sites. It allows MSN/AIM and Y! to work without prompting the first time, for example. So far, I have no complaints.
I tossed the free version of AVG (grisoft.com) on my mom's computer, which is old and was full of virii and spyware. I've been very happy with it, as I don't have to fix her computer every time I go home. There's a 30 day trial on the website, and I think there's a free version somewhere on there, as well.
There's a beta of a firewall/antivirus thing now that seems to work pretty well on her computer, as well. I installed that the last time I was home.
This is a sample I used in some VBA code embedded in an Excel spreadsheet. This line checked if the cell value was blank. You could use the line in an "If-then" setup to set the .value parameter to the random number. Sheet#.Cells(X, Y).
