investigation of weird virus thing in my gmod

this thing first showed up around august of 2007, idk how it got here. its making my game unplayable when i go near it, ive crashed on multible occasions. i dont think its power is limited to gm_construct, ive seen it in big city when ever i try making the barney show episode 3. i just want to get this thing out of my game

images of this virus thing:

theories:

• its some sort of malware/virus
• it comes with gmod (doubt it)
• its all in my head
