It's not advised to ring them as there won't really be anything they can do to help you.

NOTE

The current round of Word/Excel/XML attachments are targeted at Windows users.

Apple and Android software can open these attachments and may even manage to run the macro embedded inside the attachment.

The auto-download file is normally a windows executable and so will not currently run on  any operating system, apart from Windows.

However, if you are an Apple/Android user and forward the message to a Windows user, you will them put them at risk of opening the attachment and auto-downloading the malware.

Currently these attachments try to auto-download Dridex, which is designed to

steal login information regarding your bank accounts (either by key logging, taking auto-screens hots or copying information from your clipboard (copy/paste))

Cheers,
Steve

We are running exchange 2010, i have added a transport rule for any .xlsx or .doc attachments which prefixed the subject with "Suspicious attachment" and adds a disclaimer at the bottom of the message body advising the user to delete the message if they weren't expecting it.

Hopefully this info will help somebody else
