Generally speaking, make it a point NOT to click on
Attachments to an email. And if you receive an email
from an address you trust that has an Attachment,
do NOT click on it until you check with the Sender that
they, personally, sent it to you . There are people out
there that "steal" email addresses, then send malware
in an Attachment and the recipient thinks it was from the
trusted & reliable Sender. And delete Junk Mail as quickly
as possible .
