Hi.

I'm reevaluating my antivirus situation.  I've started to read
negative things about Norton AntiVirus (my current and now expired
solution) here and there and have decided to consider other
options.

Please find a handful of articles where the current crop of anti-virus
products are compared against each other.

Hi donphiltrodt:

Thanks for the interesting question. 

Here is my list of recent (i.e., no earlier than 2004) reviews/comparisons of 
antivirus software. I've sorted them in what I think is the order of
greatest relevance to your original criteria.

"Protecting your data is getting harder every day.   With more people
using broadband connections, file sharing utilities, and
sending/receiving email along with virus writers developing more
sophisticated ways to attack, a good anti-virus package is imperative.
  This site, Anti-Virus Software Review, is a tool to help you
understand virus issues and to determine which solution gives you the
most protection for your computer system and files."
Note: Puts the product comparison in a single, really nice, easy-to-read table.

Quote: "Antivirus software is must-have protection. This review picks
the best antivirus software based on its virus detection abilities,
features, and breadth of protection. Whether you're seeking total
system coverage or an ala carte solution, each of the following
products provides superb virus protection for Windows-based PCs.
Because every system is unique, evaluate several of these antivirus
products to find the software best suited for your PC and your level
of experience."
 
While several of these reviews rate Norton AntiVirus highly, most of
them don't put it at (or near) the top of their lists of
recommendations.

Search Strategy (on Google):
* "antivirus software" review
* "antivirus software" comparison
* "antivirus software" "top 10"

I hope this helps.
