Opex is a worm that spreads through the P2P (peer-to-peer) file-sharing applications: KaZaA, eDonkey and Morpheus.
Opex creates a large number of copies of itself in the default shared directories of these programs and in a random folder in the My Documents directory. The names of these files refer to IT applications, games, screensavers etc. By doing this, other users will download copies of the virus to their computer, thinking that they are downloading utilities.

Opex is difficult to recognize, as it does not display any warnings or messages that indicate that it has infected a computer.
