Using the trial version downloaded just now please note that the download size of Kamo is 135MB.
As far as I can see Kamo is a rename/variation of Trackoff which Avast purchased last year.
At the moment the uninstaller is not signed so you may have issues with your AV when you uninstall it.
Only Internet Explorer and Legacy Edge are supported it seems.
By default Kamo is set to run when you boot your machine.
Default whitelisted cookies are ccleaner, Piriform, Avast and AVG.
If you highlight a cookie from the suggested whitelist you can click add
