How to remove Symantec uninstall leftovers: SymSilent, Norton Activation Helper Service and Symantec Eraser Service

I've uninstalled (as explained in https://support.norton.com) Norton Security 22.9.2.3 (preinstalled in my new notebook with Windows 10  64 bit) via the Control Panel; subsequently I've used the latest Remove and Reinstall tool (NRnR.exe with "remove only" option).
I'm very angry because, despite to Symantec assertions, I've found a lot of leftovers here:
 
1)FOLDERS:  
C:\Program Files (x86)\SymSilent
C:\Users\Public\Symantec\SymSilent

2) SERVICES:
"Norton Activation Helper" (Automatic and Started) related with "SymSilent.exe" in C:\Program Files (x86)\SymSilent
"Symantec Eraser Service" (Automatic and Stopped, version 116.2.1) related with "NS.exe" in C:\Program Files (x86)\Common Files\Symantec Shared\EENGINE (but the folder Symantec Shared is absent)
3) REGISTRY:
RegScanner (a Nirsoft free utility) lists a lot of keys containing the strings "Symantec", "Symantec Shared", "Symantec Eraser Service" and "SymSilent"; the most important are located in :
HKLM\SOFTWARE\Symantec\SymSilent
HKLM\SYSTEM\ControlSet001\Services\SymSilent
HKLM\SYSTEM\ControlSet001\Services\EraserSvc11621

 
No doubt that SymSilent.exe is a Symantec file as explained barely here: https://support.norton.com/sp/en/us/home/current/solutions/v108042047_En...
This executable properties are:


File description: Symantec Application
Product Name: SymSilent
Copyright: Copyright (C) 2017 Symantec Corporation
Version: 7.9.0.41
Dimension: 1,02 MB (1.071.488 byte)
MD5: 5656D23207C3580964CD0505ECDC89FC
SHA1: C2219D8B3C2282E4384E8A98B285F242EA4E1223
SHA256: 5561B2360A5E08A8CE3C90D04EFD44D056D97335D1E5C10E1EB31535A38DF12F
Digital Signature (sha 1 - sha256): Symantec Corporation
Language: English (USA)
 
No uninstall routine is provided for SymSilent and so also advanced uninstallers (ie. TU, Revo,Ashampoo) are obviously unable to detect and remove this "hidden" active application.

Typing in elevated command prompt things like "C:\Program Files (x86)\SymSilent\SymSilent.exe/uninstall" is totally unuseful.

For sure Symantec knows this aged problem because many people in the past (starting from 2012!!!) have lamented it in various forum and also in the Community.It's evident this indifference.

I've read that somebody has solved  some problems described here by calling  them.
For taking SymSilent away they need to enter your registry remotely but absolutely I don't really intend to do a thing like this and I'm wondering why Symantec doesn't write instead a public tutorial about this procedure.
Another tortuous alternative is the manual removal of  files, folders, services and registry keys related to Symantec/Norton but this way can bring unpredictable consequences in OS; for example I've tried to remove "Symantec Eraser Service" by deleting (after a backup) the key HKLM\SYSTEM\ControlSet001\Services\EraserSvc11621 ... but it remains listed in Services window and an error string appears inside the second column (Description).
 
Any other better solution ?
Thanks for the help and pardon my poor english.

Hello Mattew Boot your system in safe mode using this guide. Manually remove all the entries you have found then reboot. I would stay as far away from AShampoo products as possible since they present security risks in their usage.
