About 3-4 weeks ago my computer overheated, after that the internet was very slow i tried finding solutions to fixing the problem but nothing has worked, i tried using malwarebytes antimalware, superanti spyware, AVG free 8.0, CCleaner, ATF-cleaner, and smitfraud fix. malwarebytes, superanti, and AVG all found viruses and removed them. but that didnt fix anything. so i then used CCleaner and ATF cleaner and free'd up some space btu that still did not fix anything. how do i gain my internet speed back? please help
