Eset has for a while been touting their 0-day protection, but with the number of signature updates per day, I have to wonder if that claim has any truth at all. Here one of the number's from eset site: "Approximately 88% of threats are proactively detected using ThreatSense heuristics." 88% !!! Then why so many signature updates per day ? I have to assume that the customer is not protected between the time the malware is released and customer receives the signature updates from ESET. Also, why the False Positives. http://www.av-comparatives.org/seiten/ergebnisse_2006_05.php. My organization would love to try out NOD32 but we need ZERO FPs, not "low", not "very low", but "none". Cleanup after an FP is incredibly expensive, far more than a worm outbreak.
