After reading this thread and other comments on Amazon, I am abandoning my plan to purchase upgrades for NIS (I'm currently using NIS 2003 successfully on two computers). In this thread, I saw one person advocate PC-cillin and several praising either AVG and Avast!. In addition to NAV, NIS also includes the internet security and firewall functions. Do these other products cover those functions as well or just the anti-virus functions?

Add'l background in case it impacts anything: running XP SP2 on 2 computers, one a Dell Latitude and the other a Dell Desktop. Using with a Linksys router but no additional firewall installed for the router. Both computers are also running NSW (one 2003 and the other 2005) without problems (at least not since I de-installed Norton Anti-spam). The 2005 I will probably renew, not upgrade or replace. Uncertain about the 2003, since I don't think I can renew it, but with NSW, the primary reason to keep it may be Norton Utilities. From an earlier experience, I don't have any interest in McAfee (and probably not Zone Alarm either).

Thanks for your thoughts.
