If nothing is showing up in the Infected Files section of the chest, then the send to chest function is failing, are you getting any errors ?

The move to chest may fail for a number of reasons, the location of the file, commonly in the system folders, or they are in use and as such protected by windows. This is why it is important to know the file name of the file infected with the win32.HAXdoor-GJ Trojan and where that file is located.

If there is nothing in the chest to give this information, try the avast! Log Viewer, right click the avast icon and select ‘avast! Log Viewer,’ check the Warning section of the viewer, it should contain information on virus detections.
