OK.
Well, when I try to modify that file Windows tells me it is in use and I can't save. Even if I disable Self-Defense. Now, I could edit the file from a Live-CD or something but I shouldn't have to go through all that trouble just because an update won't show up on the 'stable' channel. If it was pushed to stable it should appear, right?
Edit: OK I did it the hard way. Rootkit-detection is now disabled. Also Exploit-detection. Now I can test. However I now have a notification about the disabled Rootkit-detection that I can't dismiss. Slightly annoying but OK.
Also: why is Avast still popping up with a warning about editing Avast-files when Self-Defense has been disabled?
