We all know background services are crucial for running applications and features on Windows operating system. This article addresses an issue which you may face, if root services are not running.
In Windows Security (earlier Windows Defender), we came around following message under Virus & threat protection tile:

Threat service has stopped. Restart it now.
Although, we’ve a message at the Dashboard that device is being protected but actually it wasn’t 100% protected. The reason behind this fact is non-working of threat services as mentioned in Virus & threat protection tile. So to fix this problem, we hit Restart now however, nothing changed, the error stays there, even if we restart machine.
