scam mail

Got this in email this morning:
'Hello,
Please find attached the credit card authorization form for Sandra
I will not be checking in with her but I do want all of the charges to be billed to my card on file.
Please let me know if there is anything else that you will need.
Radh*a'
There was an attachment 'authorization form' to click on.
Haven't seen this one before

This went around a few years ago. The attachment is a virus. (Usually.)
