Because this signature has the [cryp] indicates it is encrypted I don't know how accurately the scan can be as it is encrypted.
Is this Tradewinds 2 a game that you have installed yourself and has it been on your system for some time ?
If so it is possible that the encryption is to protect copyright (I don't know that for sure), but normally there shouldn't be much reason for files to be encrypted.
This is by WildTangent, Inc. and is often associated with adware/spyware, so there may well be something in there that is considered spyware.
You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner and
report the findings here the URL in the Address bar of the VT results page. You can't do this with the file securely in the chest, you need to extract it to a temporary (not original) location first, see below.
- avast5 - Create a folder called
Suspect in the
C:\ drive. Now exclude that folder in the
File System Shield, Expert Settings, Exclusions, Add, type (or copy and paste) C:\Suspect\* That will stop the File System Shield scanning any file you put in that folder. Now enter the chest again and Extract the file to the Suspect folder and upload it to VT.

So personally I would be looming at uninstalling this game if there is any doubt about it at all.
