Facebook Malware and what to do

I recently received an unusual message/app request on my facebook page:

This is an example of Facebook malware. These work like computer malware infections. The main purpose is to steal your personal information. So... in general, I don' to any Facebook apps, though I occasionally violate the rule. I make sure that my security settings are appropriate to do this. Unfortunately, many of the apps want my email address, etc, which makes me vulnerable to real computer malware.

So... I've written a document, based on an existing document, describing how to manage this problem. It is How to Prevent Facebook Malware.
