AACW.exe - PCK/ExeCryptor identified by Avira

[spelk]

I've been having issues with the Anti-Virus software Avira and my copy of AACW. Upon scanning, it throws up a detection of the following threat "PCK/ExeCryptor" in the AACW.exe file.

Assuming this to be a false positive, I send the file in for further interrogation to Avira Labs just to be on the safe side, and they returned the following analysis:

Filename Result
AACW.exe RISK

The file 'AACW.exe' has been determined to be 'RISK'. Our analysts named the threat PCK/ExeCryptor. File has been compressed with an unusual runtime compression tool. Please make sure that this file comes from a trustworthy source. This file is detected by a special detection routine from the engine module.
Please note that Avira's proactive heuristic detection module AHeAD detected this threat up front without the latest VDF update as: %AHEAD_NAME%.

I'm sure all is well, it's just a little unnerving that Avira have processed the false positive claim on the file and come up with it still flagged as a risk.

Is this a cause for worry?
