Post-Malware /CPU running at 100% until task manager is opened

[MariaFAR]

Hello, 

About 2 weeks ago (May 23rd) I downloaded a link for some software from Utorrent and some malware was installed on my laptop. 

I ran disc clean up on the system files while in safe boot and ran malwarebytes and it quarantined the infected files. I ran a scan again and it did not detect anything. 

After that, I installed Kaspersky total security and ran a scan with nothing detected.

Ever since then, however, the laptop has been very slow to start up, and the fan is always running at its maximum speed and laptop overheats a lot. 

CPU is at 100% unless I open task manager, then it goes down to very low, normal ranges around 5%... 

I have read a lot of posts about this and it seems there might still be some malware or infected files on my laptop which the software cannot detect. 

I don't know how to tell which processes are the ones causing this high CPU usage and I do not want to end any tasks so as not to mess up the system. 

Can you please help me fix this issue? 

Thank you

NOTES:

I can help you to check this Windows pc for malware.

I would like to know what ( if any ) third-party (non-Microsoft) antivirus was ever installed on this pc.

NOTE:

Other than Task Manager, what are you looking at to judge the "CPU busy" % ?

Can you perhaps try to get a screen-snapshot-grab image of what you are seeing  about CPU usage?

Thank you.
