For me, the only way to remove the ESS beta or the standalone EAV beta, was to use the Eset uninstaller tool listed above. I had then no problems with removing the AV, but sometimes I lost connectivity with the removal of the ESS.
Therefore I would recommend either a system restore or restoring a backup image before installing these products (the re-installation of the network adapter also worked when uninstalling ESS).
I would not blame Eset though as I have had uninstall problems on WIN 10 with nearly all the other AV's I have tried (more than 5).
