I got Windows 7 Ultimate 64bit installed everything was going great, I was playing Dying Light and it was buttery smooth. Then I accidentally got malware and everything hit rock bottom. I tried to clean up everything with Avast, Malwarebytes and CCleaner but i am still experiencing horrible performance. What can I do to fix this? Help is much appreciated!!! Thank you!
