What to note?
However, it’s important to note that the Safety Scanner is not intended to replace your regular antivirus solution, as it lacks real-time protection and automatic updates. Instead, it serves as an additional tool to scan and remove infections when you suspect that your current security software might not be functioning optimally or if you believe your device has been compromised. One key thing to be aware of is that the Microsoft Safety Scanner is only valid for ten days. After this period, you will need to download an updated version to ensure you have the most recent security threat definitions and enhancements.
