Infected by Katuna, after much cleaning, still many CPU cyc. when idle

I got infected by the Katuna virus this past week. I have performed a half-dozen different varieties of cleaning using different softwares, and still have a high consumption of CPU when computer is idle. How do I resolve this, if somebody would be so kind as to help me, please?

Thanks in advance,

What antivirus do you have? download malwarebytes (as it will not hinder an antivirus already installed on your computer) and see what it says.

Never (besides malwarebytes) have two antiviruses installed at the same time. Also, never uninstall an antivirus without using an antivirus removal tool. I can further help you out after you let me know about your AV setup. waiting to hear back
