In all honesty there is very little in the filesystemshield.ini file and virtually all of my settings are the defaults.
I had increased my sensitivity to High and have had that for ages and in the earlier beta builds without this problem. I first backed that off to the default, Normal and then to Low, neither of which made any difference.
Then the only differences would be what exclusions I have entered, but they shouldn't impact/increase the scan frequency (repetitive nature) of the scanning.
However, looking at yours, it bears no resemblance to mine at all, but the ones that you have I have and are pretty much the same. But I have lots more. So I don't know if it has inherited some of my old avast6 settings.
