Heroic Launcher Is Now AUR: Is It Safe To Remove?

I noticed today that heroic-games-launcher is in the Cachy-Update tray icon in an AUR menu. It is also one of two packages listed when I run "sudo pacman -Qm" (the other being jack). I have never used Shelly or paru, only pacman, and even before the attack I decided to avoid AUR completely. Nor have I used Cachy-Update, only pacman -Syu. So, I'm not sure why either of those are there. Is there a way to safely remove them? Or is it even necessary?

​

​

I have only used Steam but I read elsewhere that Heroic is a dependency. Maybe I could replace Heroic with a non-AUR version somehow? I have already run the script and found no known infected packages.

​

I would appreciate any support, thanks!
