Why is an unremovable Policy for "QuicAllowed" making Google Chrome tell me it's managed by my organisation?

Question

Why is a registry key appearing in HKLM:\Software\Policies\Google\Chrome!QuicAllowed? It reappears on reboot if I delete it. Its presence is causing Google Chrome to tell me that the browser is managed by my organisation, but I have no organisation managing things.

It is not the result of an extension as opening an incognito window causes the data to still show.
I am using Bullguard Antivirus.

Solution

This is caused by Bullguard Antivirus' Safe Browsing feature.

Hey, thank you for getting back to us. Please note this is required for our Safe Browsing, to display the green checkmarks, but if this inconvenient for you please open BullGuard, click Settings from the top > Advanced > Antivirus > Safe Browsing and disable Google from there. Alternatively, try disabling all the ticks from there and see if you still have an issue.
