What is the security product that stops the most zero-day threats?

When your systems are affected by unknown viruses and worms, scanning traditional signature-based technology is insufficient. Every minute counts and the expected time to update your antivirus is the time when your computer and your network are vulnerable to damage, infection, or identity theft. The heuristic ThreatSense identifying and stopping malware as it runs on your computer, closes the window when you are vulnerable.
NOD32 has consistently been the most important test centers as the best protection against zero day attacks.www.av-comparatives.org is an Austrian research lab that performs retrospective tests.www.virustotal.com publishes a newsletter listing vendors that detect outbreaks as they occur.


AV-Comparatives
The organization indipentente AV-Comparatives.org is an antivirus research project coordinated by Andreas Clementi with the support dell'Innsbrucker Kompetenzzentrum / Computernotdienst. The Retrospective / Proactive Test by AV-Comparatives.org compared 11 different antivirus products to test their ability to proactively identify today's zero-day threats, increasingly complex. The stringent testing used recent samples of virus in the wild and a variety of other malware, Trojans, viruses and worms for operating systems Windows and other systems. In order to test effectively for proactive detection, the research center has used new malware samples, the products without updating the antivirus signature.

VirusTotal.comThis independent consulting company based in Spain and performs real-time analysis of malware on a wide range of antivirus products. As you can see from the chart below, NOD32 is by far the product with the highest detection rate, as well as the one with the best performance (tested separately by Virus Bulletin). On average NOD32 is 2 to 10 times faster than the competition.
