If you experience any kind (CPU, disk, slowdowns) of performance issue on a computer running Avast  (Windows 8 and above), please try to follow this simple procedure and share the performance logs with us.

- download the configuration file from http://public.avast.com/~nix/users/wpr/avast-profile.wprp to some local folder (this step is not necessary on newest installation of Avast Antivirus)
- launch the elevated command line (cmd.exe as Administrator)
- go to the folder with downloaded file avast-profile.wprp
- start recording via command wpr.exe -start avast-profile.wprp (or with newest Avast Antivirus: wpr.exe -start "c:\ProgramData\Avast Software\Avast\profile.wprp")
- reproduce the performance issue (e.g. if this is happening at the very same time, please "just" wait about a minute or two)
- stop recording via command wpr -stop avast-log.etl
- ZIP the log file avast-log.etl and share it via some cloud storage (google-drive, dropbox, one-drive) or avast FTP sever
- provide a link to the zipped log file via avast forum

Thank you very much, this procedure won't collect any documents or personal information from you computer. It is just recording all process activities running on the PC so we can analyze what is happening during the recording period. If you are interested in the analysis yourself, your can use the tool "Windows Performance Analyzer" from "Windows Assessment Toolkit" (https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install).

note: if you are running older OS (e.g. Windows 7) you can install the older version of Windows Performance Toolkit (http://public.avast.com/~nix/users/xperf/xperf_x86.msi for 32-bit OS, or http://public.avast.com/~nix/users/xperf/xperf_x64.msi for 64-bit OS) and use different start ("xperf.exe -on DiagEasy+DISPATCHER+Profile -stackwalk profile+CSwitch+ReadyThread -start avast -f \avast.etl -on 1492D477-3272-5C0C-D91A-C156CC3CD206") and stop (xperf.exe -stop -stop avast -d avast-log.etl) commands in the procedure above.

  • Come on lad! You've only got 70 yards to go.
I have uploaded an avast-etl logfile in a zip file name to the Avast FTP server "manofkent1949@gmail.com.zip"

This has been sent because Avast Free 22.5 is slowing my Toshiba Satellite Pro laptop.  Asyn suggested I send it to you at ftp://ftp.avast.com/incoming/

Hi loungehake, thank you for your report. I have checked your logs and I don't see any CPU or disk consumption by Avast processes there. The disk is mostly idle and the CPU is consumed by the Firefox and Speedyfox processes. Could you please provide more details, what is slowed down (which task / operation), how much is it slowed and ideally please provide two performance logs, one for the situation with Avast installed and second one without Avast installed. Thank you.

Now that Avast have received your upload, you should modify your post to remove exposure to that email address as I have done in the quote.
