Issue pmm-ras.exe infected? Symantec detected WS.Reputation.1

[nethubonline]

After upgrade the Plesk to most updated version: Plesk Onyx Version 17.5.3 Update #22 , Backup manager becomes not accessible, it is same to this KB: Backup manager is not accessible: The system cannot find the file specified

We checked the reason becuase Symantec Endpoint Protection detects pmm-ras.exe infected by WS.Reputation.1 , so that the file is quarantined and make the Backup manager fails.

However, it is weird that I download pmm-ras.exe again today, Symantec doesn't show alert anymore......

Below is the report from Symantec Endpoint Protection

WS.Reputation.1 is a detection for files that have a low reputation score based on analyzing data from Symantec's community of users and therefore are likely to be security risks. Detections of this type are based on Symantec's reputation-based security technology.

That is, it is not a virus, even from the point of view of the Symantec. Just a kind of mistrust.
I would suggest do not use any third-party antivirus software on Plesk server.
