C-Media CMI8738/C3DX audio driver install fail

Guys please help me! ASAP.

So my problem is all about my cmi8738/c3dx onboard audio chip.
The problem just show up after I remove those trojans that I found on my PC using Malwarebytes. After removing those trojans, I restarted my PC then after restarting, I just notice that no sound are coming out in our speaker. I check whether the speaker is broken or not, and it is not. Then I check if the icon of the mixer is there, it's there. But when I check it on the control panel, it shows that there are no installed audio driver.
So I un-install the cmi8738 audio driver on my PC. But when I tried to install a new driver, the setup stops at the ksuser.dll file then the setup fails to install the driver.
Also, at the end of the setup, which fails to install the driver, it always says this words: "the I/o operation has been aborted because of either a thread exit or an application request".

What should I do? Please help me.
I'm waiting for your reply. Thanks in advance.

EDIT: I managed to fix it now, I just use the Microsoft recovery console to fix this problem.
