This configuration is a solid configuration in my opinion. But ESET still does not cover what VoodooShield covers. VS is an anti exe which also queries Virustotal whenever an unknown file is executed. Is VS absolutely necessary when using ESET? Not at all. But VS complements ESET very well since ESET does not have a Trusted Application Mode like Kaspersky. If one uses KIS I find VS redundant.
The free version is good enough, as long as you have a standard system. With the pro, you can do things like move your downloads folder somewhere else but still have full protection for it, you can have different settings for different users, you can tweak this and that... but the basic protection is the same
If your download folder is located outside of your user profile, for instance, you put it on a different partition, then VS at default settings will not monitor it, when VS toggles to OFF. The sign of this state is when the icon turns red (ON is blue). In this state, only high-risk areas are monitored.
That's what Dan has said in the past. When VS is toggled OFF, the protection is relaxed so that the system might be able to run a task that was blocked when the more aggressive protection of ON was applied. For this reason, in smart mode -- which is the recommended mode -- VS will automatically toggle OFF after X minutes of user inactivity.
Like @shmu26 said, the Free version is good to go if you don't need tweaking. Set it to Always On and you're good to go. I have a promotional license for VS Pro and so I'm using it. Once it expires I'll stick to the Free version. Protection wise they should be the same.
He is not on this forum.
With Comodo Internet Security, the rest are redundant. Configure CIS properly and you're good to go. Just toss an adblocker and syshardener.
