That is the reason why we ask about the file, location and malware name as I think that it is win32:Trojan-gen
The three ... dots signify that there is more info (concatenated) you can expand the column width by left click and hold whilst dragging the mouse pointer to the right (this works in most windows applications with columns.
The avast Win32:Trojan-gen is generic signature (the -gen at the end of the malware name), so that is trying to catch multiple variants of the same type of malware and is a fine balance between detecting a new variant and detecting something valid as infected. So you should confirm the detection, see below.
When you open the chest, Infected Files section, highlight the file, right click on it and select scan.
- The only area you should be interested in is the Infected Files section, this is where the files detected by avast and selected by you to move to the chest are placed.
- The User Files section is where the user can add files they suspect of being malware but not detected by avast.
- The System Files section is where avast keeps back-up copies of important system files in case the original becomes infected (leave them alone).

You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner and
report the findings here. 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.
Create a folder called Suspect in the C:\ drive, e.g. C:\Suspect. Now exclude that folder in the
Standard Shield, Customize, Advanced, Add, type (or copy and paste) C:\Suspect\* That will stop the standard shield scanning any file you put in that folder. You should now be able to export any file in the chest to this folder and upload it to VirusTotal without avast alerting.
If it is indeed a false positive, see
http://forum.avast.com/index.php?topic=34950.msg293451#msg293451, how to report it to avast! and what to do to exclude them until the problem is corrected.
