I am sure it is as well. The automatic blocking of Flowscape may however present a problem for some users of F-Secure anti virus software. No doubt F-secure will put Flowscape on the white list.
Meanwhile I am running the program and have fallen in love with it. :-)
EDIT: 03-07-2019 (DMY)
F-secure have/will updated the whitelist with Flowscape:
"Our analysis has found that the file you submitted is clean.
We have identified the issue as a False Positive, which will be resolved automatically via F-Secure's Security Cloud."
