Actually, I think ESET heuristics is better than avast. Based on AV comparatives.
Robots always have better heuristics, this should come as no surprise.
Marcus said on WIlders that ESET have one of the fastest response time. Not sure how true is that.
Robots also have very fast response time, pretty hard for humans to beat the whole "organized central intelligence" thing that they have going for them.
Just wait for the Pirate Robots, I'm telling you. The prototypes are already out there, Google pirate robots and you will see.
Avast!'s Version 7 Anti-Malware Pirate Robots, driven by the power of community, Czech programming, cheap rum, and a lust for booty and pillage.
I pity the competition.
