Hello Malwarebytes forum! My computer has been running very slow and the CPU usage is constantly at 90 to 100%. When I try to type something online, I have to type very slowly, otherwise the letters will not show up properly (I have to wait for each letter to show up before typing the next one). I have searched around the web but cannot find a solution. There are 4 processes that take up the most CPU. These are: - dllhost.exe (COM Surrogate 32bit) - TiWorker.exe (Windows Module Installer Worker) - upnpcont.exe (UPNP Device Host Container 32bit) - dvdupgrd.exe (DVDUpgrd 32bit) I ran a Malwarebytes scan but nothing showed up, and no folders or files were quarantined. I'm a novice with computers, so I need some help fixing up my PC. Thank you!
