This is much like the Ford or Chevy discussion. Both work well with XP and have updates when needed or such.
Updates are driven by factors that are driven to a schedule of "daily, weekly, monthly" but by when some malware writer lets a new bug loose that makes an impact.
Free AVG is noteworthy as well.

got access to 2 antivirus programs and was wondering what others thought of them
1. trend-micro PC-Cillin
2. Panda antivirus
i have heard that both do pretty good just wondering which one others felt was the better program. looking for ease of use and regular updates
