The Security Mentor

There's a university that does some usually underreported studies of how effective different antivirus products are.

Their latest antivirus test results are out, and my old favorite has slipped several places down the list.

As a practical matter, any of the top five or ten should do just fine for you. The difference between the best and the fifth best is nothing compared to the difference you get by staying out of bad neighborhoods and subscribing to regular updates.
