After working so hard it's difficult to keep it to ourselves, so it's time for a little blatant self-promotion. SuspectFile.com, a well known malware support forum in Italy, has recently finished its 2007 AV Report (italian / english), focusing on proactive detection via generic signatures and heuristics of undetected malware samples found infecting user machines in the wild. In its review of 25 different vendors, it had this to say about our engine:

Panda. Nothing has changed since last year, was and remains the top product. The best. If we want to trust in a safe product, this is what every kind of users needs, expert or not. First in heuristics, we found no false positive. The proactive defense is what impressed us the most. During the last 5 years, this product has made giant leaps. The relation user/vendor is really the "icing on the cake". Absolutely recommended product.

There are other similar studies like the one CastleCops MIRT
runs in real-time, but what I liked about this study is that it gives a
clearer picture as it also takes into consideration engine speed and False Positives thrown by the different heuristic engines.

Keep up the good work Marco & Lucass !!
