On Tuesday, McAfee Avert Labs discovered W32/Realor.worm in
the wild that was actively modifying all Real Media (*.rmvb) files in
its path. These “infected” media files launch a malicious webpage
without prompting, as they are being viewed by the user in Real media
player. These files can be music or videos hosted on a network drive
containing corporate presentations, a personal media server, or a P2P
shared folder et cetera. When was the last time you hesitated in
opening a movie file ?
