My CPU usage spikes constantly from the under 10% range to over 70%
This has just started since the most recent update. I have ran a full system scan and there have been no security threats. I run live update multiple times a day with smart definitions off.
I still have 80GB free on my hard drive
My laptop was never slow before.
