Emsisoft + ESET scanner is actually a good option.Emsisoft appears to be the better option based on the comments, it also comes with a powerful Behavioural Blocker.
You can still use ESET detections' capabilities, but on-demand only with their ESET Online Scanner software, which installs to your PC and requires an Internet connection prior to use. However, it should not interfere with Emsisoft or vice-versa.
With ESET Online Scanner alongside your other on-demand scanning tools.
I completely forgot that ESET provides an on-demand scanner.
Thank you for your suggestion.
