Hello Shaiful, thank you for reaching out to the Microsoft Community. I'm here to help with your questions or issues. Just note – this is a place where passionate Microsoft users help each other, we don't work directly for Microsoft.
About your issue, coinminers can be quite persistent, and you might need to take more thorough steps to remove them. You've already taken some good measures, but let's try an additional approach:
Download and install Kaspersky TDSSKiller to search for any rootkits that might be hiding deeper. You can get it from this link: https://usa.kaspersky.com/content/custom/global...
Please let me know if it detects anything.
