This thread comes to show how tricky it can be when an av-solution decides to mingle with essential system files or files that are essential for proper driver functioning with a particular OS. The appropriate party should be the developer in full cooperation with that particular Operating System team, e.g. a patch to tackle the problems/flaws should be issued.
Whenever those parties involved are not helping out, I can imagine an av-solution steps in with all the consequences we see now.
