Since you have limited RAM (I only have 4gb, so I can relate) I would consider giving Windows Defender a trail run.
I recommend this because you said you've not faced a recent attack, indicating to me you are a knowledgeable user.
*And remember in 1703 you can adjust settings to allow apps from Windows store only. Essentially acting as a anti .exe for you.
However if you wish to continue with ESET it is certainly a excellent AV by any standard.
