Issue Virus Ransomware .Osiris

Hello Team Avast,
In Customer we have a problem infected ransomeware that is located in the PC client.
PC Client has been using avast standalone client endpoint protection suite and program version alredy lastest update versi 8.0.1609.
Virusransomware change file extention be .osiris, change file name and encrpt file.
Please help make anti for type ransomeware .osiris to be detected by anti-virus avast. So the future is to use avast products will not be affected by another type of ransomware .osiris.
I send a file that has been exposed ransomeware .osiris to link ftp://ftp.avast.com/incoming.
Do avast provides features to detect anti ransomware , because in a few months is a lot of ransomware that attacks on our customer. If not, my advice hopefully there Fiture anti ransomware.

Thankyou Team Avast.

Thanks & Best Regard,
Dominic
