KKF 1.4.2 is, simply put, a utility to find working keys for your Kaspersky products (Antivirus or Internet Security), which you have no doubt obtained illegally (such as from my favorite, http://www.demonoid.com/files/details/1594305/19013640).
It will search for valid keys for the following products:
Kaspersky Anti-Virus (KAV) Versions 5-7
Kaspersky Internet Security (KIS) Versions 6, 7, and 8 (2009)

This is the quiksilv3r release which I believe has all of the required DLLs, etc., built-in; it is the only one that I've found that isn't itself flagged by Kaspersky or NOD32 as some sort of virus/hacktool, and I trust it much more than those that are.
FYI, I personally recommend Kaspersky Internet Security 2009 over, say, ESET NOD32. "KIS" seems to be much better at finding/preventing problems.
