My friend and I have been searching our game for things that may be causing lag and I found this:

It's a model, with a module script for EVERY script in the game. Is this supposed to be in every ROBLOX game - is it just supposed to be hidden? I need to know so I can figure out whether I can and should delete it or if it's a virus etc...

Here's some code from one of them, it's literally just "return" and then a multi line comment of everything in the script:

return [[local destroyBlur = 0

local function fade()
	for i = 1,100 do
		script.Parent.TextTransparency = script.Parent.TextTransparency - 0.01
		script.Parent.TextStrokeTransparency = script.Parent.TextStrokeTransparency - 0.01
		wait(.01)
	end
	wait(1)
	for i = 1,100 do
		script.Parent.TextTransparency = script.Parent.TextTransparency + 0.01
		script.Parent.TextStrokeTransparency = script.Parent.TextStrokeTransparency + 0.01
		wait(.01)
	end
end]]

I don't see how this could possibly be useful to any other script in the game, since it's just a comment.
