Windows Defender is an inbuilt app you get with Windows 10 PC. It comes from Microsoft and is actually reliable. It can run timely scans and remove malware if found on your PC. Now, it may happen that sometimes while scanning for viruses the Defender may get stuck. This means it will take more time than usual to scan a particular file or folder.
The virus scanning is carried out by the MsMpEng.exe. It is the primary component of Windows Defender. When scanning it gets stuck, which may consume 100 percent of the hard disk drive and CPU.
