At the very least they are social engineering attempts to get you to run the two files inside the .zip and these may well then go on to download malware.
If you still have copies of these two .exe files, add them to the chest and send to avast.
Send the sample/s to avast as a Undetected Malware:
Open the chest and right click in the Chest and select 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.
