What's this system tray icon?

I dont know but try right clicking on your taskbar, select properties and click on the customize button you might find it there

That's the second thing I tried after clicking and hovering failed me, but it doesn't show up anywhere on the list, reverse image search gives me no results either.

Do you have the antivirus software Avast?

Ha, I have exactly the same problem as this guy, the tray icon appears on my second monitor only, it's gotta be from Avast, but I have no idea how to disable it. I have another computer with virtually identical settings and softwares that also has Avast, but the icon doesn't show up there, weird.

Got it. It's Avast VPN. Just went into components and disabled the thing and now it's gone. Thanks >>287636
