This site http://www.av-comparatives.org/ contains the best up-to-date comparision I’ve found of anti-virus software. I notice that eSet’s NOD product has outscored all others. Users report that it’s fast and unobtrusive. Older versions had a lame user interface but I’ve read that it’s now improved.
As always in the world of computers, Caveat Emptor.
