An alternative would be to go to a commercial office center with computer work stations available. Such as FedEx Office. Sign on to one of their computers -- thirty cents a minute at FedEx in New York -- and try and open the email. The commercial places have very robust malware detection and AV programs. If the attachment looks hinky when scanned the computer will warn you and won't let you open it.
I agree with some of the others, however, when I occasionally get an email that looks suspicious I delete it on sight. I even go to the Recently Deleted folder and delete it from there. Especially if it arrives in a group pending file, I don't hesitate, it's history.
