VBMania is a computer worm that successfully attacked many computers running the Microsoft Windows operating system in 2010 when it was sent as a link inside an email message with the text "Here you have" in the subject line. The final extension of the link was hidden by default, leading unsuspecting users to think it was a mere PDF file. Upon opening the attachment, the worm sent a copy of itself to everyone in the Windows Address Book.

This is the email the worm sends.
