Scam Warnings.
I have received a couple of these emails now. They tell me that my Facebook Password has been changed and the details are contained within the attached file. This surprised me somewhat as I do not have a Facebook account!
Norton found the attachment (passwordxxxxxxx.zip (xxxxxxx is a 7 digit number, different in each email)) to contain a file called facebook_password.exe which was was the Trojan.Sasfis.
Trojan.Sasfis will install itself into your Windows based computer and set itself to run at start up. It connects to a server on the internet and may download and install more nasty things from there.
Good advice is to Never click on Any ".exe" file that you receive via email (unless sent by prior arrangement). Even something that just "turns up" and seems to be from a person or company that you know and trust could be a nasty wanting to infect your computer.
