Avast Scan Option in Win 7 Recycle Bin

I am using Win 7 Home Premium.

After putting a file in the Recycle bin, I right-click and there is an option for Avast to scan it for viruses.

Q1. Why would there be a scan option in the recycle bin folder?
Q2. Why is the file named ‘$RRH9F4N.docx’ instead of its original name?

Once the recycle bin is emptied, AVG does not offer to scan.

Anyone have an idea?
