Have you gotten this email saying "We could not deliver your parcel"? I've seen a couple of variants pretending to be from FedEx and from UPS and I'll wager there are others out there. I've gotten it with different wording, too. They're all crap.
Client called the other day and asked about an email from InterFax in his inbox. On the surface the email looks legit, but the attachment is a .zip file and that's a big red flag!
You are your own best defense against spam based virus attacks. Take a moment to read incoming messages thoroughly and review these three points before clicking on attachments or links in an email.
I found this in my spam filter yesterday. It purports to be from the payroll company, ADP. It was easy for me to spot it as SPAM, since we don't use ADP for payroll processing. But even that weren't the case, that there's a .zip file attached to this email would have raised a red-flag.
