Whenever I'm playing games, Chinese symbols appear on the screen, I can see the text box, and when I hover over the green arrow you can see in the picture, it says "print string", so I'm not sure if it's some sort of SDK, I've done virus scans and malware scans, and the games and OS I'm using are all legitimate copies, just wondering if there's anyone who knows what it is, and how to remove it.

click here in advance.

Thanks
