I have an Asus laptop and have been having this for about 2-3 years now. Everything was perfect; Games was running well until i downloaded a file that contained a virus. I did a full scan and also rebooted my laptop and deleted every single file i have. I re-installed my games and FPS is still dropping and I can't find the reason why. My cousin told me i could still have a malware infection, although my scan says i don't. I don't believe that it can be my fan or any other reasons because before i downloaded that file, it just messed up my FPS rate. I have Kaspersky. Here are my specs:
Asus k501ux Intel core i7-6500U 2.50GHz 2.59GHz
NVIDIA GEFORCE GTX 950m, Windows 10 64 bit 8 GB
