Avast Software Analyzer / aswbISDAgent using high CPU

Since a few months i have high cpu usage on all cpu’s and my fans are running loudly. It really says very high energy consumption on all 8 processors. Cause is the aswbISDAgent. The why i don’t know. Sometime the usage goes down some even under 18%. Most times it is above 26% and higher and stays there.

Can someone tell me why this is and why this strange behaviour? I have the premium security and the cleanup premium. So not the free products.

None, just the Windows defender

  • Which AV(s) did you use before Avast…?

I use only Avast for a couple of years. On this system nothing.
This Windows is clean installed some time ago without the pre-installed software by myself.

  1. Download Avast Premium Security: https://files.avast.com/iavs9x/avast_premium_security_setup_offline.exe
  2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)
  3. Reinstall Avast with the downloaded installer from point 1.
  4. Reboot.

Okay i will try this.
I’ll let you know.

thanks.

You’re welcome.

After de-installation, restart and installation it works fine. It uses at this point like 2 to 3 % cpu resources. And that’s normal.

Thanks for the feedback.
