Microsoft Safety Scanner is not meant to be used as a day-to-day tool, since it does not provide real-time protection against viruses, cannot update its virus definitions and expires after ten days. On the other hand, it can be run on a computer which already has an antivirus product without any potential interference. Therefore, it can be used to scan a computer where there is a potential infection and the user wants a second check from another antivirus.[5] It uses the same detection engine and malware definitions that Microsoft Security Essentials and Microsoft Forefront Endpoint Protection use.[6][7]
