Its a 2011 beta test. You only see Sonar working towards the end, but it really does well. Watch the vast majority of the files that made it past the virus-scanner disappear! Got at least 90% of them - now that is the most impressive video of any reputational/behavioural AV I have ever seen.
Nice to see Symantec is working hard - and getting it right!
