This really should have been in its own topic in the viruses and worms forum. This is a program beta topic and viruses/malware are handled outside of the program version itself.

I can’t see avast specifying a particular day (they would first have to have a sample/s).

I also haven’t any idea what it is you are trying to have them correct, the video in itself aside from the language is long. so I don’t watch it through. Presumably you ran some samples in a VM environment, checked by hitman pro and then by avast.

Any samples that weren’t detected should be sent directly to avast for analysis and inclusion (if conformed) in the virus definitions update.
