Possible false positive

[Xanadu]

I did a quick scan this evening and Avast! found four files that it said were infected with Win64:Dropper (DRP).  They are all part of my beats audio system.  All files in those folders have the same "last modified date" of 3/29/13.  The four files are all alike - located in four places on the machine. Windows and the IDT folder.  sstray64 is a legitimate file per research on the net.  I know they can be changed with a virus but with 54 cleans on the virus total...false positive?

I uploaded to Virus Total and it says it is clean.

This was not found the last time I scanned.  No warnings from Avast on anything. 
Windows 8.1.1.
Avast! 2014.9.0.2021

I don't want to obliterate my audio over a false positive.  Can someone help please?

I do not have to tell you if there is injection into the file
send the file to be analyzed virus@avast.com  "False positive" in email subject.

compressed with Zip or RAR password "virus" or "infected"

or else send through the virus chest

The files are quarantined in the chest.  I submitted through the virus chest.  I submitted two - one from windows location and one from program files location.

Once in the chest they can sit there without causing any damage.
My suggestion is to leave them be for a week or two. Then open the
chest and "right click" an re-scan right from the chest. If they then
come out clean "right click" and restore to their original place.

Ok. Thank you for the additional information.  I was just wondering how long to wait to recheck them.  Thank you! 
I appreciate the help you guys give.

I waited for a couple updates and then decided to rescan within the virus chest.  They now all scan as "no virus".  So this was a false positive correct and it is safe to restore these files?
