Avast! & Kernel-Mode Driver Framework version 1.9 update for Windows 2000, for Windows XP, for Windows Server 2003, for Windows Vista, and for Windows Server 2008 (kb970158).
On this rag-computer I use since year and day Avast Free. Like I suggest my clients if they can’t make a choice and, of course, if they don’t want to pay. 
Last Tuesday Microsoft had updated the Windows, then I had to do the rest. Avast!, first definition updates. Then there appears still to be a program update, approximately v.11 to v.12.
I installed, and then suddenly I’m happy with my old rag computer because one update does not fire just past:
Kernel-Mode Driver Framework version 1.9 update for Windows 2000, for Windows XP, for Windows Server 2003, for Windows Vista and for Windows Server 2008( https://support.microsoft.com/nl-nl/kb/970158 )
Which is from 2011.
What does this Driver Kit suddenly do in Avast!?!?!? Why???
I asked Google, and still found no answer.I just want to know WHY Avast! this framework Driver Kit integrates. Nothing more.
I myself in my younger years toyed with driver kits, provided by Microsoft, but it was above and beyond me.
Meanwhile, I looked up the Avast! forum, and there through the search engine (ie Avast!), I found 3 (three) ENTRIES (INPUTS), 1 explaining the driver kit, what I already knew.
Why integrates Avast! this Driver Kit?
C ++, VB, understandable. To present a slick interface …
But a Kernel Mode Driver?
Just a fantasy: A driver is corrupted. Avast! pulls it apart, eliminating corruption, and put the driver back together…
You picture it? .
