Random crap is being added like welds,touch interest how would I prevent this?

So Like whenever I do things crazy things like weird things I dont need like touch interest welds keep being added by roblox and idk why bruh

any way to fix this?

From what little information provided it sounds like a virus script you have in your game. These scripts originate from the toolbox. I would recommend that you look through all the scripts that came in a model and see if they contain anything that looks devious and remove them.
