I think there is a blanket warning on such e-mails. Never click on a link in an unexpected e-mail.
Even be wary of spam from companies you have bought from (maybe be especially wary since such a coincidence increases trust).
If one needs to investigate to put one's mind at ease type in the known to be correct web address directly, copy nothing from the e-mail nor click on it.
They're doing the rounds, I had a fake PayPal one a weel or so back.
I even had a 'Ben Stone'(odd name for a resident of ?Calcutta?) phone my landline from Microsoft yesterday asking to speak to the person who uses my computer.
Er.....that would be me.
Oddly, been appeared a little irked as I bade him goodbye after 10 seconds......
