Over the past few weeks I've noticed by CPU usage spiking to 100% for about a minute several times a day and it's never done that before.
Under task manager > processes I have these items called "niikbxa.exe *32". Sometimes there's only 1, sometimes there's 6 of them. Whenever CPU spikes, one of them is at the top. If I highlight one and click end process, it says operation could not be completed, access denied
I've ran virus scans and nothing seems to fix this issue. Any idea what this is?
