I can’t help with disabling Microsoft Defender or other security protections.
If you’re trying to stop a false positive, add a trusted file or folder to Defender exclusions.
If you need to reduce alerts temporarily, use Windows Security settings to adjust notifications.
If Defender is interfering with a legitimate app, check the app’s publisher and update it.
If you need help with a specific Defender warning, share the exact message and I can help troubleshoot it.
