AVG antivirus was detecting Actions Server as an unknown but possible virus, an issue that sometimes happens with antiviruses, it's called a "false detection" and it is already happened several times to other developers.
We sent out a “false detection report” to AVG so they were able to correct this in their virus database.
The latest AVG major update to version 2013.0.2741 with virus database 2616/5851 (24. Oct. 2012, 08:34) has fixed the problem. Thanks to our customer Patrick G. for the report!
If you still have issues with AVG detection please update it with the latest database.
If you still have issues after the update let us know.
