    Avast using 15-30% CPU in idle


    I installed Avast anti-virus free on my new Windows 10 install, and now I'm noticing the CPU constantly fluctuating around 15-30%, when the computer is just sitting idle. Task Manager shows it is Avast.

    What component of Avast is constantly running my CPU so high, and can it be disabled?

    Hi.
    I'm not sure what component is causing that - there used to be something called NG that I found to be problematic, but I think they call it something else now (related to VMs). At any rate, when I install Avast on a system, here's what I select:

    You can go into Installed Programs through Control Panel and select Avast, then select Change and uninstall the other components that way.

    In uninstalled all but the 3 shields and software updater, and the CPU is now hovering around 0. I wonder which component was causing the high CPU? I had Rescue disk, Browser Protection, SafeZone browser, SecureLine, Cleanup, and Browser Cleanup installed.

    How is Browser Protection different from Web shield?

    Good to hear.

    I'm not sure. Probably a quick Google search will answer that.

    EDIT: Please mark the thread as solved, if you are satisfied. Cheers!

    I've run Avast for some time using only the 3 real-time protection shields, Repair Disk, [on-demand] Network scanner. I do not recommend using Software Updater, as far as I remember, end-user has no control over what is updated and what is not updated. Somebody correct if I'm incorrect, thanks!

    Software updater only updates if you ask it to, in the free version. Not sure how it functions in the paid version (never used that). I find it useful to see what needs updating, and then go perform the updates myself.

    I found Avast Free beginning to eat resource & stopped installing it on my family & friends' laptops. Avira free is my current selection

    I thought AVAST was light on resources, at least some time ago. It seems it isn't true nowadays. I've heard good things about AVIRA, but I am quite satisfied with WD so far.

    Thanks for the kind correction! My assumption based on the first appearing board misled me, I stand corrected.

    I don't know - you could be right about the paid version. And if it did do that, it would bother me a lot!
