Microsoft Defender Antivirus and firewall 100 % clean?

Tags: Malware, Security, Windows

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
Microsoft Defender firewall on

Done Full scan = clean

Would you trust, that the laptop / system is clean?

Thank you

Yes. I trust it, but maybe you don’t.

Apart from what a fellow mod already said, if you don’t think it’s clean, get a damp cloth and wipe it down. That will help.

In all seriousness, it sounds like you took the appropriate precautions. Worst case, format the SDD/HDD and restore to factory settings. Make sure you have some type of file backup/cloud storage.

Same answer despite new info?

Done Full scan = clean
I did that after the laptop went online

And according to:

Malware Protection Test March 2024

The offline detection rate is mediocre

But the Real-time protection was on when the laptop was online, and still on after the laptop went offline.

Would you still trust, that the laptop / system is clean?

I did not clarify in my original post, if it was online or offline manual scan.

And according to:

The online / cloud scan, is way better than the offline scan.
The offline scan is mediocre.

But the Real-time protection was on when the laptop was online, and still on after the laptop went offline.

1.
So you would trust, that the Real-time proctection would instantly stop anything malicous?

2.
Because the Real-time proction scan uses the cloud / online scan?

3.
Or what other arguments do you have, that you trust that the laptop / system is clean?

Thank you

It’s clean because it’s yours. Given your interest in security I don’t expect any device used by you to be not clean.
