Avast Free keep wanting me to restart and is hogging CPU

Hi there I am new here. I tried searching for related posts but they are old and I didn’t find answers. I have used Avast for years no problem but for a while now it has been using a bunch of CPU and I am getting messages saying it needs me to restart the computer. Any idea how to fix this? I feel like deleting the program maybe trying a different antivirus?
