It is possible that you may see a window appear after starting up your Mac that looks like the image below.
This is Apple's Gatekeeper software verifying VirusBarrier's permission to work on your Mac. This is normal and expected behavior and is not malicious in any way. These processes (AntiviralLibZ.framework and WindowsAScanner-184.108.40.206.framework) are associated with VirusBarrier. These processes will resolve and the windows will disappear once the verification is complete. No action is required from the user.
