The best way to check your PC for malware

Microsoft Defender in Windows 11 runs automatic scans, shows a green checkmark when no threats are found, and logs actions in the Protection history tab; a Full scan or offline scan can be initiated for deeper inspection. Malwarebytes offers a free on-demand scanner with Quick, Custom, and Deep scan options, and its AdwCleaner tool targets adware that other scanners may miss. Both tools provide alerts and options to quarantine or delete detected malware.
