I never open attachments myself...
It seems like virus writers are finally incorporating a bit more knowledge of the engrish language into their emailed social engineering attempts...
The subject & bodies of the viruses we recieve started changing today...
I think a lot of people will be tricked by some of these:
Subject: scanned by norton antivirus
Body: you cannot hide yourself! (see photo)
Attachment: material.zip
Subject: Returned Mail
Body: Information about you
Attachment: misc.zip
Subject: YOUR ACCOUNT HAS EXPIRED
Body: I have your password
Attachment: notes.zip
They mix up the subjects, bodies & attachments of course.... but as of today I noticed the new ones that are even more deceiving.
