Step 3: Temporarily Disable Firewall & Antivirus

Your security suite may be mistakenly flagging the activation as a threat.

  • Windows Defender: Go to Settings > Privacy & Security > Windows Security > Virus & threat protection > Manage settings and turn off Real-time protection (temporarily).
  • Third-party AV (Norton, McAfee, Kaspersky): Right-click the icon in your system tray and select "Disable" or "Pause Protection" for 15 minutes.
