PIF

(Program Information File) In earlier Windows versions (3.x and NT), a PIF file stored custom display settings (window size, fonts, etc.) for a DOS application. The DOS app could be launched by clicking its PIF file, and the PIFEDIT.EXE utility was used to create them.

Starting with Windows 9x and 2000, PIF was replaced by Properties. Viewing and editing settings for a DOS application works the same as a Windows resource by right clicking the icon and selecting Properties.

Sophos is warning users to be wary of a virulent new email-aware worm, called Netsky-D (aka W32/Netsky-D), which is currently spreading via email disguised as a PIF file. Sophos has so far received many reports of this worm spreading in the wild, clogging up email boxes around the world.
Instead of running WP.EXE immediately, Windows first looks along the search path for a WordPerfect PIF file. It assumes it has found one if it locates one with the same name as the executable file (WP, in this case) and a .PIF extension, i.e., WP.PIF.
It will insist on using the applications's PIF file, and if it can't find one, it will use a default PIF.
