Create a folder called Suspect in the [b]C:[/b] drive. Now exclude that folder in the File System Shield, 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.
Now Open the chest - avastUI, Maintenance, Virus Chest - Right click on the file within the chest and select, Extract. From the next window navigate to the newly created C:\Suspect folder and click OK.
A copy of the file will now be in that folder and one remains in the virus chest - now you are good to upload it to virustotal.
