CPU usage high until i open task manager

[zieg01]

Hello,

I built a new pc a month ago and it's been doing great until a few days ago that I noticed my cpu at 50% plus when idle/browsing with no heavy programs running. Everytime I run the task manager or similar programs I downloaded online, the CPU usage will always go down to around 1-5%. I ran a total scan using avast and I dont see any malicious file. I can't see what process/program is the culprit because everytime I check it on the task manager, the usage will suddenly drop and I can no longer see which one is using all the cpu. I've seen similar posts online and here, and tried to resolve it but I dont see any suspicious file and I really don't know which process is the malware.

My Setup is:

i7 8700k Processor, GTX 1060 6gb, 8GB Ram, Windows 10.

I hope you can help me find some solution or better yet pinpoint the cause.

Forgive my english.

Thanks a lot=)

Hello,

 

Thank you so much for the swift response. I ran Malwarebytes several times and it finally found this "Trojan.BitCoinMiner.BatBitRst". After monitoring my computer overnight, the issue is resolved! I don't see the cpu rising more than 5% on idle/browsing anymore. I also downloaded AdwCleaner and it found something on my chrome folder. I opted to clean it just to make sure. You're a great help=)
