How to remove an infection through a script?

So I was inserting a build kit into my place like I usually do. I guess it wasn't the same build kit because this one included an infection. I didn't realize till it's to late and it's making my game lag. I might be wrong but I'm pretty sure there is a script to remove it.

You don't need any plugin for this one
