Keep it zipped

[billsstamps]

I use Rules and Alerts in Microsoft Outlook to dump rubbish emails into my Spam file.

There is one thing I haven't worked out how to do. Can anyone help?

I want automatically to move all incoming emails with a zip attachment, .zip, to go into my Spam file.

I got malware emails from "Fedex" and "American Airlines" today with virus in a zip file. I want to make sure that I don't accidentally open such a file
