Perform a full system scan in order to detect any malware running on your computer. You can use Windows’ built-in antivirus, Windows Defender, or third-party antivirus solutions. We recommend Bitdefender – rated as Nr. 1 world’s best Antivirus it will find all the malware on your PC and completely eliminate the threats.

Solution 3 — Check your disk for errors

On Windows 10, you can run a disk check using Command Prompt.

As a quick reminder, if you do not use the /f parameter, chkdsk displays a message that the file needs to be fixed, but it does not fix any errors. The chkdsk D: /f command detects and repairs logical issues affecting your drive. To repair physical issues, run the /r parameter as well.

Note: This process can be time consuming. Depending on the hard drive’s memory, it can go between half an hour and two hours before it is done.
