To do this, go to “Windows Security” > “Virus & threat protection,” and click the “Quick scan” button. If you want to do a more thorough scan, which will take longer but will check all your files and running programs, you can instead click the “Scan options” button, and choose “Full scan.”
How do I manually detect malware?
Open your Windows Security settings. Select Virus & threat protection > Scan options. Select Windows Defender Offline scan, and then select Scan now.
