I didn't expect it for at least a week, but I received a virus in my new Gmail account.
I didn't realize it was a virus at first, so I clicked on the part that says "Message.rar". Now, before you email me telling me "That was stupid." let me explain my actions. I was a bit concerned since my signature used to read "Google is watching you. If you're worried about privacy, use my other email address - firstname.lastname@example.org", and I didn't want to lose my account after only having it for less than a week. Still, I admit it was a pretty stupid thing to do, especially since there are several glaring clues. I think it's because I'm used to Hotmail; despite the perceived "evil" of Hotmail, they have a pretty decent policy of blocking one's ability to download viruses. Gmail does scan email for viruses, the attachment still made it onto my computer - maybe they can't scan .rar files?
I shouldn't have expected to see my enemy unmasked at this point, but I was given the option to "Show original".
I pasted the text instead of posting an image so people can read the content of the header directly. Tricky bastard. I'm no expert on forged headers, but I'm pretty sure that this message isn't from the staff at Gmail. It may come as a surprise that someone who's worried about privacy would click on an attachment and not question its origin, but I'd like to think that I'm not the only one susceptible to lapses in judgment. I'll be more cautious from now on, but I hope Gmail fixes that security hole.
