From my IT dept.:
If you receive e-mail with attached zip file, don't open it unless you're sure of it's content. See note below, it could be a virus. Will let you know when things are resolved.
We have had reports of spam with subjects like the following:
Order ID : 37679041 Is Being Processed
The samples I have seen come from firstname.lastname@example.org
(it is spoofed) and it is usually sent to someone other than the person who received it.
The email contains a zip file which probably contains malware or worse. Users should not open it. They can delete it or leave it untouched.
In the meantime, we are blocking Zip files from being received from the Internet. The blocked content will be examined before delivering.
