Best Way To Secure The Network.
Q: I have my three small business computers networked via WI-FI router. Two running XP and one Vista. Each CP is used to access the internet and e-mail. What is the best way to secure them (the network). Would each CP need a separate firewall Other then Windows) and virus software subscription? Or can this be installed on one CP only and protecting the others?
A: WPA2 for the wireless with a good password, built-in firewall, all security/high-priority updates for the OS installed, good and frequently updated antivirus software, strong user passwords for all accounts the machine accesses as well as for the machine logon and common sense. every computer should have its own antivirus. A personal firewall may also be a good idea, and the Windows firewalls on XP and Vista are good. Every computer should have its own antivirus. A personal firewall may also be a good idea, and the Windows firewalls on XP and Vista are good enough if not better than others. Good point and one I am sure the OP would have caught onto fairly quickly as they visited the web pages of each. AVG: http://free.avg.com/download-avg-anti-virus-free-edition "AVG Anti-Virus Free Edition is only available for single computer use for home and non commercial use." Avast: http://avast.com/eng/avast_4_home.html "This edition is FREE OF CHARGE for non-commercial & home use only. Both of these conditions should be met!

"Avira AntiVir Personal is a comprehensive, easy to use antivirus program, designed to offer reliable free of charge virus protection to home-users, for personal use only, and is not for business or commercial use." Then what I recommended (going with NOD32) is still valid and what I would recommend for the OP. Looks like the going rate right now for eSet NOD32 is $106.99 for three of the 2-year licenses of the NOD32 AntiVirus product - which is what I would likely do in the OPs case (mentioned they had three machines.) http://www.eset.com/purchase/ (Home and Home Office tab ...) Later - if a SBS gets involved as you grow - call and discuss an upgrade/price cut if you are still under the original license terms.
