I'm looking for suggestions on an AV program that is best in these categories in order of importance: 1. Detection and cleaning (this would include frequency of updates) 2. Resources used 3. Ease of use 4. Support (doesn't have to be "personal" - self support is ok) 5. Full features available for Windows NT/2000/XP systems I know that program XXX may be the best at detection and cleaning but may be a memory/resource hog. Program YYY may be easy to use and have great support but doesn't detect and clean very well. I'm currently using NAV but looking elsewhere due to the resources used and the full features aren't available for Windows 2000 which I use on my primary computer. So taking all these factors into consideration, which would you recommend? Thanks.
