Hi,
I'm Paul and I'm here to help you with your concern.
Can you try to use Autoruns?
- Download the Autoruns(https://docs.microsoft.com/en-us/sysinternals/d...)
- Extract the file(Autoruns.zip).
- Open the extracted folder then run Autoruns.exe as Administrator.
- Once the Autorun is open, click the 'Logon' tab.
- Find the process related to "Armoury Crate".
- Right-click that process, click Delete.
- Close the program then restart the PC.
I hope this helps. Feel free to ask back any questions and keep me posted.
