I have Avast Internet Security 19.2.2364 (build 19.2.4186.437) and I started noticing that every 20 - 30 min. (sometimes even shorter) Avast suddenly take so much computing power that my mouse become erratic and any thing that I'm running or interacting with get interrupted. This feels like something that happened years ago, but has now resurfaced. It's becomming extrememly distracting. I have trouble playing simple games or watching videos.
