Rav Mon E virus
Also called W32/Rjump, this virus is known to open a back door on a computer that runs Microsoft Windows, then create a copy of itself in the Windows system directory of a computer. Italso creates a log file that includes the port number on which the back door component listens. The Rav Mon E virus enables hackers to gain access to the computer's programs and files once it has become infected. If you are using an anti-software program that is is up-to-date the RavMon E virus can usually be detected before it does any damage. This virus is most commonly spread through e-mail attachments, although it can also be spread through portable devices such as multimedia players and digital cameras.
Apple reported that in October of 2006 many of its video iPods had been shipped out with the RavMon E virus already installed on them.
