The attached image shows a strange bug caused by ESET Smart Security (8.0.319.1) on Windows 10 x64. When I'm using Microsoft Edge and there are several tabs open and I drag a tab from the top bar to the left to move it near another tab this exact warning shows up. Nothing else happens when I click on the warning. The bug reappears every time I move a tab to another position, which is very odd.
Can someone reproduce and confirm this bug?
