Welcome to the Virus Encyclopedia of Panda Security.
Parite.B is a polymorphic virus that creates a dropper type file in the affected computer and infects files with EXE (executable) and SCR (screensaver) extensions.
Parite.B spreads through the usual means used by viruses, (CD-ROMS, e-mail, Internet downloads, etc.). Furthermore, it also spreads across networks. When it has infected a computer in a network, it enumerates all the shared network drives in order to copy itself to them.
Parite.B is difficult to recognize, as it does not display any message or warnings that indicate that it has infected a computer.
