Ever since about a month the ESET console keeps stealing the focus from Firefox. That is, the console is never visible, but my keyboard hits never reach the window I am looking at. I figured out it was ESET through a simple CLI tool called focus.exe and verified by Microsoft's procexp64.exe:
4960:C:\Program Files\Mozilla Firefox\firefox.exe | Tue Apr 09 16:28:53 2019
4308:C:\Program Files\ESET\ESET Security\egui.exe | Tue Apr 09 16:29:16 2019
Apparently this happens whenever a URL is loaded that contains certain content that ESET feels it must analyze. Especially annoying when the tab is supposed to load in the background.
To reproduce load https://what-if.xkcd.com/155/ and load the " well-equipped fire department" link near the bottom in a new tab.
Any clues how to stop this behaviour?
