OPTION 1 - Windows Defender

The new version of Windows 10 has a built-in application called "Windows Defender", which allows you to check your computer for viruses and remove malware, which is difficult to remove in a running operating system.

Keep in mind that System File Checker (SFC) cannot fix integrity errors for those system files that are currently being used by operating system. To fix these files you have to run SFC command through the command prompt in the Windows recovery environment.

This operation will take a while and it is important to wait until it is complete. When finished, close the command prompt and restart the computer as usual.
