If you haven’t already done so submit it to avast as undetected malware.

Send the sample to avast as a Undetected Malware:
Open the chest and right click in the Chest and Add, navigate to where you have the sample and add it to the chest (see image). Once in the chest, 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.
