Send the sample to avast as a possible False Positive:
Open the chest and right click on the file and select 'Submit to virus lab...' complete the form and submit, the file will be uploaded during the next update.
You could also check the offending/suspect file at: VirusTotal - Multi engine on-line virus scanner
and report the findings here, post the URL in the Address bar of the VT results page
. 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. Now exclude that folder in the File System Shield, Expert Settings, Exclusions, Add
, type (or copy and paste) C:\Suspect\*
That will stop the File System Shield scanning any file you put in that folder.
