Well, it must be virus season.
I just received another suspicious file, via Yahoo.
Very suspicious extension of attachment
* data.dat.scr
Sender: ***** <*****.******@mail.aim.com>
Recipient: **********@yahoo.co.uk
Subject: Good day
Avast alerted me to a suspicious file extension, yet again. A screensaver extension this time, so be careful, expecially (it seems) with Yahoo accounts. So if you get an email with "Good day" in the subject field, be careful about opening it. Obviously, I never opened the attachment, so don't know what's in there (malware, virus etc).
