The Novarg (or MyDoom) virus was unleashed yesterday afternoon (I received at least 20 copies of the virus at work myself). Disguised as an error message, when the attached file (usually a zip file) is launched, it sends out 100 infected e-mails in 30 seconds, to addresses located in your computer’s address book. The virus may also open a “back door” to your computer, so that hackers can take control of the PC. Virus definitions have been updated to fight this new threat — update your virus definitions now.
