Hi everyone,. I have just installed Windows 2003 Server on my system and was looking for a good and Free antivirus solution for my system. I searched the forum, and could figure out AVG, Kaspersky and Trend Micro and Avast as the possible options. I have used AVG on XP previously, never had any problem, but it cannot be installed on a server, so it stands eliminated. Could anyone suggest me about the other options available (It should be free)?
