Firefox virus?

Good day, I need help.
Recently I bought the entire Tomb Raider collection on steam, and with that, I tried to look for some software that would emulate the keyboard inputs on my controller. Needles to say, I think I downloaded a virus by an accident.

Whenever I start up my PC, a program with a Firefox icon also starts up and then disappears. I don't use Firefox on my PC, so it's even weirder. I have no idea how to dispose of it, I scanned my PC using Windows Defender (scanned twice) and Bitdefender.

Windows defender indeed detected something, I let it do it's thing to remove it. I scanned 2nd time, apparently the virus was gone. Used bitdefender to scan once again, nothing detected, and yet it still pops up. Here's how it looks like.

Note: when I was making this screenshot, my background changed from red to black, and when I turned off rainmeter and tried to click on the black background, start menu would pop up. Please help.

UPDATE: I went in and checked task manager if it's still there, since I didn't kill its proces this time. It was. I checked the details and it seemed like a legit firefox thingy. The name of this exe file was "update", with a firefox icon, although it wasn't in a Firefox folder ('casue... I don't have firefox installed) but it was in a folder called "HorizonPC" in C:\Program Files(86x)\Common files
