Brief Description 

    

Opaserv.P is a worm that is considered dangerous, as when it has carried out its infection it ends a large number of processes in the affected computer and then deletes the content of the hard disk.

Opaserv.P spreads through shared local resources and network drives.

Opaserv.P is easy to identifiy, as when it has carried out its infection it restarts the infected computer and displays a message in an MS-DOS window:
