Lately I've had some spare time and have started playing an old FPS multiplayer game every now and then. I randomly checked the games folder in my C drive today and there was a jpeg added to the games main folder 3 weeks ago titled 'noob'. The screenshot is of me playing in game. I never added or took a screenshot (let alone named one). The servers I play in are modded. For this jpeg to get into my game file, does this mean I was hacked? I only noticed the file today and it was added 3 weeks ago. Nothing notable has happened in the past 3 weeks on my computer, other than computer occasionally crashing and internet sometimes being very slow. I was thinking maybe an admin was able to add screenshots to someones game rather than me actually being 'hacked', however I'm not sure. I've scanned with 2 AV (including malwarebites) and nothing has came up. I'm quite confused how a named random screenshot/jpeg could be added to my games folder.
Was I hacked and should I be concerned?
