Today I was sent a fax eFax which attempted to download a ZIP file from the internet. This seems to be yet another method for the creators of viruses and malware to spread their payload. Always be cautious when receiving unexpected email messages. I was suspicious of this message, as I do not have an eFax account. There is also no reason that someone would try to send a fax to my email address.
Here is the text from the message I received via email.
