i create password because i want to protect avast member here , please try at vmware/virtualbox
it blocked by FileRep-malware
but just want test behavior protection , only disable file system shield , others default setting
result : failed to protected
Hi,
It is blocked by filerepmalware.Maybe someone from avast team as to why IDP didn’t block it?
I will try contacting someone from avast team on this.
IDP (behavior shield) is by no means supposed to be the only shield running; it is a complement to file system shield and web shield. While there are some samples that are detected by only one (or two) of the most important shields, I do not consider it a fail 
But we of course work very hard to improve individual shields ;)!
As I expected! Thanks for shedding some light.
really appreaciate and thx for the work hard ;D
try this one , now avast miss detect

Avast hardened mode aggressive will protect you from that but Avast CC and BB/BS failed to recognize this new ransomware.So no matter what you are protected. 
Its blocked too
Avast labs are very quick to react to new ransom samples
Just because VT doesn’t say we detect doesn’t mean avast doesn’t block the url or the binary:

This may have been flagged first by filerep then by their labs as malware-gen
