Constant CPU usage 30-50% on laptop (not during scans)

Badge +3
Hi! On my job laptop i'm constantly getting high CPU usage, somewhat crippling the machine and keeping the fans busy. This goes on for 24/7 no matter if I restart.

Any idea how to fix it?

Hello @kpax

Welcome top the Webroot Community,

Would you please do an uninstall/reinstall of Webroot following instructions below and see if this high CPU issues is fixed?

  • Make sure you have a copy of your 20 Character Alphanumeric Keycode! Example: SA69-AAAA-A783-DE78-XXXX

  • Download a Copy Here (Best Buy Geek Squad Subscription PC users click HERE) Let us know if it is the Mac version you need
  • Uninstall WSA and Reboot
  • Install with the new installer, enter your Keycode and DO NOT import any old settings as you can set it up as you like once it's done

I have to go through the company support to do this as it is controlled by them. Why are you suggesting reinstall? A sensitive part of a system like this should be essential to find the cause no matter what it is. Just "ignoring" it would work for regular consumer products but not a antivirus. It is bad bad practice in my opinion as a software developer.

Do you know which version you're running by chance?
