Newer Virus samples, escaping most scanners

There's no surprise for me at all.

If those malware sample are completely new or rarely spread in the wild or it's adware/spyware-like or it brings no danger so most of AV will miss them, even you send those malware sample to an AV companies but I think not all AV companies will add them to their database or some will take so long to do.

But according to my malware collection and from my experience Kaspersky seems to be the only AV that will care those mentioned malware and maybe they will add to database as soon as you send sample to its virus lab.

That's why I personally praise Kaspersky as the best to protect users from all possible type of malware.

 

Umm...MKS/ArcaVir will also add zoo samples if ppl send them in. I'm sure.
