Obviously the AnchorFree TAP is part of Bitdefender's VPN. I have the unlimited version of it.
Actually the few times I've used it, it's pretty good.
I've ranged anywhere for 3*mbps-5*maps download speeds and 5*maps upload speeds on Speedtest.net with it.
Without it I get 100-13*maps download and 10.*-11.*maps uploads.
Now, I know though, if I ever have to uninstall and re-install Bitdefender for any reason, uninstall the VPN first.
Bitdefender support told me try uninstalling and re-installing Bitdefender the other day, to see if it fixed the AutoPiloot issue. It did.
So far the only bug is Windows 10 1803's Privacy>Background Apps not remembering what you don't want always running in the background after you configure it and shutdown or restart your pc.
It's back to not wanting to scroll again, too.
Theirs more than what the screenshot shows.
