Appears that this email is doing the rounds at the moment, received this one at about 4:00pm today, but apparently been around for quite a while in some form or another according to search’s on Google.
First Clue that is a fake was the address that it came from which was a legitimate address, just not a BT associated one.
Second Clue is that BT Digital Vault is a service that is no longer offered by BT and it’s in fact been replaced by BT Cloud.
So if anyone gets an email like the one shown below, I suggest you delete it immediately and do not attempt to open the zip file attachment, which as you would suspect contains a virus/malware payload, just waiting to infect the unlucky users PC.
