Hello everyone,

Can anyone tell the reason Avast Service uses 50% of my CPU usage and 1000MB of RAM consistently?

It's really slowing down my computer and I would love to get help, Screenshot is attached.

Thanks and have a great week!

I did what you suggested and it solve the problem.

Now the CPU usage is low (Going from 0% to 40% but mostly it's down, and RAM usage is 350MB.

Thank you so much!

A quick update:

It goes back up to 30% CPU and 500MB RAM consistent.

Is this behavior is usual?
There is a way to lower this percentage of usage by unchecking/turning off certain Settings?

Thanks once again!

It depends... If the system is idle, no.
