Just recently, someone tried to send me a .pif file over MSN, I was a little wary at first, but a quick search on google told me it was a worm. I was wondering if it really was, I've never heard of a .pif file, and I'm, well... a computer geek in some ways. So will every .pif file be a worm? Or only certain ones... and if anyone cares, the file name was: naked_drunk.pif This person isn't really a friend, just someone I know from an AA clan.
This info was taken form this site.
A Program Information File dates back to the early versions of Windows. Basically, it's an information file that when you click on it the information in the file is used by Windows to run some program; including code that can be in the PIF file. It is a potentially dangerous file type and one should never click on one received via E-mail without extensive knowledge of exactly what it will do first. Note: This file type can become infected and should be carefully scanned if someone sends you a file with this extension.
So to answer your question, no. Definately do not ever open a .pif file someone sends you. Block that ass that sent it to you and inform his clan that one of their own was trying to infect you.

Here is mEk's post about it, probably the same little wormie you got.
I didn't get no worm, I nearly did though.
