Roblox studio plugin infection, and can i fix it?

Alright so i got on roblox studio to build and junk, and when i went to go test it out, it kept giving me this "HD grapics" script that's hidden, and every time i do find a way to remove one because there is two scripts, it just comes back. It does this with all my places to, i know it's a plugin but i don't have the plugin (used to) i went through my plugins to and removed alot of them. And then there is my assumption that this is some sort of plugin infection of some sort. Please help
