Premium scan is stuck in File system for 3 hrs

[cypro]

Actually i was using a Malware Bytes free version and malwares were found and were quarantined. After some days malware through a usb stick has entered into my system. 

Then i scanned my system using the Malwarebytes free version, but the scan took  very long time and also it didnt finish. So i uninstalled the malwarebytes. After that my friend suggested me to use malware bytes removal tool and i used that too. But windows defender while scanning found a malware and removed it. But scanning again and again the same malware is shown and still defender is removing it.

So to solve this is I downloaded Malwarebytes again but this time it was a Premium trial version. Now the scan is on process but not going forward in File system scan and the file is C:\WINDOWS\SYSTEM32\API-MS-WIN-CORE-BIPTCLTAPI-L1-1-0.DLL. Now its more than 4 hours and still not going forward. System got lagged now and hard to use. Please give me a solution. I am not able to open paint or snipping tool to give screenshots.
