Hey
@joker31 It’s not clear what you mean by "scan a page to my PC." Are you trying to scan a physical document using a scanner, or are you asking about scanning a downloaded file for malware?
If you’re talking about
scanning a document, you don’t need to change any firewall or Defender settings. Just make sure your scanner is connected and use
Windows Fax and Scan or the
Windows Scan app.
If you mean
scanning a file for malware, Windows Defender does this automatically in the background. You can also right-click the file and select
Scan with Microsoft Defender to run a manual scan. No firewall settings need to be changed for this.
