Microsoft Defender Antivirus and firewall 100 % clean?

New laptop with Windows 11 pre-installed

The laptop was only online for a couple of minutes during initial setup and when downloading software from Microsoft Store

Only downloaded software from the Microsoft Store

Never visited any websites

Before it went offline:
Windows fully updated
Microsoft Defender Antivirus and Real-time protection on
