Don’t know why but 3 AVs classify it as a “potentially unwanted program”
Apart from that, what I did not like was that after scan you could not maximise the result window to see the full results and I think there was no option to select only the items you want repaired and not everything it found (in particular I wanted to unselect supposedly missing keys to libraries etc. in the registry of programs that I know I have installed and running on my computer to avoid potential problems). So it was a take it or leave it decision with the repairs it suggests and I opted out for the later and uninstalled, also because I am not happy to load on default another program on my Computer start-up when I will not be doing maintenance, I prefer to call it up when I need it.
