N.B. A few antivirus programs incorrectly flag Policy Plus as malware. Policy Plus is a powerful tool and so may cause problems if used recklessly, but it is not malicious.
No so much different than "hacking tools" or similar being detected as "malware". In other words, just another example of the paranoia typical of the authoritarianism that is so common in the software industry today.
