If you are using the integrated Windows Security solution and Microsoft Defender antivirus, Microsoft Defender Antivirus Security intelligence updates are delivered through Windows Update. Additionally, you may want to temporarily disable real-time protection while you are performing live.
Click on the Start button, type in Virus & Threat protection and then click on the Virus & threat protection app:
Click on Manage settings:
Temporarily turn off your real-time protection and Cloud-delivered protection.
If you are using other antivirus software, check their documentation on how to temporarily disable their updates and real-time protection.
Be very careful with anti-virus products. Updates can cause serious unexpected behavior such as preventing applications (including Gig Performer) from working properly and even crashing.
