Google Chrome Possible Malware/Virus

Good Day

I would just like to enquire if this “LightningNewTab” that has appeared on my google chrome is a virus or not as each time i open chrome now it completly rapes my CPU. I have tried to remove it and run a Check Disk but it still rapes my CPU…

I reckon it could be a virus or malware that is scanning my pc (Not so stealthly though)…

Please could someone with knowledge check it out and inform me what to do!?!?!?!?!?!?!?!?!?!?!?!

this one?
