Hello, recently, I've noticed that upon opening specific games (downloaded from Steam) on my computer, the rundll32.exe program begins to use around 60% of my CPU, as well as other programs like chrome and NVidia Share shooting from less than 1% to around 20%. At the same time, many games from Steam simply don't open at all, and many work perfectly fine. With malwarebytes open, the CPU usage caps at around 60%, but the moment it's closed, it shoots back up to 100%. Any idea on how this could be solved?
