Holy, Juan Diaz's tests are so brutal, so few survive..
This is why I always say 1st generation antivirus are not meant to be used alone. At least some complement/configuration/hardener say OSArmor, Hard_Configurator. 80% of infections can be covered tweaking policies and Windows functions. Reduce the attack surface in order to correctly cover the basics.
After so much time using Kaspersky/ESET, I've switched three days ago to Windows Defender +
@Andy Ful's Hard_Configurator and I've had signatures, low impact, and really effective/light default deny. I am using this on my main PC, and still using ESET on my secondary PC.
