Windows 10: CPU keeps going to 100%, something intervene anti-malware installation

My laptop keeps going on 100% CPU, but it's going down to around 10-20% when task manager is opened. I suspect my laptop got a malware and already tried to scan and remove using Windows Defender, but the issues keep going. I tried to find a solution but when i tried to install another anti-malware from other sources, something kept interrupting the process and force it to close. Anyone knows what happened? Please kindly help me to find a solution. Thanks

:)

 

McAffee and Emsisoft Anti Malware

I personally use Emsisoft Anti-Malware and IMO it is far better than McAfee...

If you decide to use Emsisoft, please make sure to fully uninstall McAfee with the help of their specific removal tool from this List
of anti-malware product removal tools before you install Emsisoft.

Suggestion to read:

  software?

FYI:

I've asked a moderator to remove the best buy link in your post. If you want to buy Emsisoft Anti Malware then it's best to go directly to their site: emsisoft.com
