Hi Dawid47,
we would like to ask you to capture xperf logs and upload it to analysis.

  1. Download xperf or wpa package it is win dependent so if you have win 10 download xperf for win 10 !
    Here is a link https://go.microsoft.com/fwlink/?linkid=2086042 and in “Select the featires you want to install” dialog keep checked only Windows Performance Toolkit !!

  2. Start cmd as admin and type to start profiling:
    xperf.exe -on DiagEasy+DISPATCHER+Profile -stackwalk profile+CSwitch+ReadyThread -start user -on 72AA3505-D4D6-4527-A088-92534DA1082C

  3. Induce the issue !

  4. Stop profiling
    xperf.exe -stop user -stop -d _merged.etl

  5. Zip _merged.etl file as Dawid47_5_2019.zip and upload it to ftp://ftp.avast.com/incoming

Thank you for report.

I can’t transfer zip file on FTP, says “Could not create a file”

FTP. https://support.avast.com/en-eu/article/FTP-file-upload

Thats not working either
I can send _merged.etl but won’t allow me to send .zip file

Ok upload it as .etl file

Done. File name “Dawid47_5_2019_merged.etl”

Thank you for uploading
cpu is used by datascan task forwarded to dev team !

Any news about it? still eating cpu like crazy

Do Repair Avast:

  1. Avast GUI → Settings → Troubleshooting
  2. Click on ‘REPAIR APP’.
  3. Follow instructions.
  4. Reboot.

Done it many times, no results

You could try the latest beta: https://forum.avast.com/index.php?board=15

:frowning:

Bad news, please wait for kwiq…

Hi,
here is what we know avastui.exe got stuck in offfiltx.dll (2006.1200.4518) which is a system dll. Other versions of offfiltx.dll seem to work properly.

Deleted corrupted one and replaced with newer, cpu at 0% load! Thank You!
