Greetings, I have recently noticed that I believe that there may be a virus on my PC. How do I know? Well, I was playing an online game and I noticed I wasn't getting my usual FPS which is 75. Instead, It has been changing between 40-50. SO I decide to open task manager and I see the CPU is around 90%+. It then drops straight after. I look on my browser and I see that the game is running at 75 FPS. When I close the task manager the game goes back to around 40 FPS. At 1st I thought it was Malwarebytes Ant-Virus as it seemed like it was causing it with high CPU Usage. I proceeded to uninstall it and it seems like it wasn't. I run AdwCleaner, says no elements found. I run my Anti-Virus, no threats found. So I'm confused as to what to do.
All help appreciated.
