I installed and used Adguard but I found it was not what I was looking for. Unfortunately, there does not seem to be an uninstaller. I checked out adguard.com, its KB articles and FAQ. There's information to uninstall it on Windows but not OS X.
There seems to be kexts installed with the app, that I'd like to remove cleanly.
Hey, I just found an easy way to uninstall Adguard. I had tried the normal ways of uninstalling apps, like sending the app to Trash, but an error message said that it couldn't because the app was open, even though I had Safari closed.
So you open Safari, from the top menu bar under "Safari", select from the dropdown list, "Preferences". A new mini window will open up with tab menu items with icons on the top. Select "Extensions" from the menu and then you should see the Adguard icon, click on it, then you should see in the main window a button that says "uninstall". Click on it, then Adguard will be safely uninstalled!
