This morning I received an email from and to my own email address entitled "Document 2" with an attachment "Document2.zip".

If you receive a similar email DO NOT OPEN IT as it is a virus that will infect your computer.

At the moment I don't know what the virus does but whatever it is, it won't be good.

UPDATE: I found this explanation online and the coincidence is that although the infected email does not appear to come from Interparcel, I did use their online service yesterday to pay for and print courier delivery labels. That must be how the scammers got hold of my email address.

The advice given in the article regarding protecting yourself from viruses is well worth reading but basically, never open an email attachment that you are not expecting.
