Kaspersky Total Security Using 25%+ of my CPU

Hi all,

For the past few months I’ve had tons of issues with my CPU usage and it’s only gotten worse.

Whenever I’m using my computer for longer than 20 minutes my fans start running immediately. As a student who has to attend hour long classes per day it’s not great. I started checking task manager and it consistently shows that Kaspersky is taking up at least 20% if not more than 25% of my CPU and my CPU in total is always around the 70%-90% use range.

Something called System and Service Host: SysMain takes up a large portion of my CPU too while Kaspersky is running. Is there any way to stop or fix this? It’s getting to the point where I just want to uninstall it.
