WARNING!

I think I may have posted something about this a few months ago, or at least something similar, however, it's worth posting again. Should you receive an e-mail that is supposedly from UPS or another carrier saying they were unable to deliver a parcel to you and it has an attachment with information on how to receive it, beware. Don't open the attachment as it probably has a virus. Here's what "Fact or Fiction" has to say:

Email From UPS or Fedex says You've Got a Shipment That Can't Be Delivered-Virus!

Summary of the eRumor: The email appears to come from United Parcel Service (UPS) or from Fedex. It says that a shipment could not be delivered and directs you to an attachment that allegedly contains the waybill so that you can arrange to receive or to pick up the shipment.

The Truth: According to UPS, this email, which began circulating in July, 2008, contains a virus. It was not sent by UPS. UPS advises not opening the attachment. The company said it may send email notifications on occasion, but that they rarely include attachments. If you receive an email from UPS and you're not sure it is authentic, you are encouraged to email customerservice@ups.com. Or call UPS to verify the existence of any undelivered shipments.
