Why do we constantly have to repeat ourselves the reasons given have nothing to do with what 'other' AVs have chosen to do, as has been said I don't know how many times, avast used to detect it but it was removed as it is a legitimate program and in itself isn't malware/spyware.
The fact that it can be misused or abused is neither here not there, avast can't detect intent, is it being used for good or evil.
