Hi lather30,
in win7 and above I would suggest xperf logs as this is the best tool for CPU issues but XP doesnt support it :-( . 

In xp i know only about procdump from : https://docs.microsoft.com/en-us/sysinternals/downloads/procdump
Disable self defense
Please download this tool and create a set of dumps with command - cmd as admin : procdump -c 50 -s 5 -n 10 AvastUI.exe
zip them and upload them to avast ftp.

Thank you

OK, I downloaded, installed and ran ProcDump using the listed commands. For some reason, it was only able to get 9 dumps, as the 10th failed to write due to an error message about a device attached to the computer having failed or stopped working - although I can't see any evidence of a problem.

Zip file of the 9 dumps it did get uploaded to FTP with the filename AvastUI.exe_180807_152731.zip.

Any progress on solving this? It's now 11 days since I uploaded the requested dumps, and I've not heard anything more about it. Is it solvable, or have I got to start looking around for a different AV program to use? Hoping for an answer one way or the other soon, as I can't afford to have the computer sat around idle for much longer.

Reported let's see if that helps.

Apparently not, as I'm still awaiting a response - now 2 weeks since the dumps were uploaded.

On the off-chance that it may help solve the problem, I updated to the latest version (18.6.2349), but the problem still remains the same, with AvastUI.exe using 95% to 99% of the CPU all of the time.

Hi bob3160,
sorry for late response as async wrote I was on vacation with limited access to internet. 
I hoped that change in avast5.ini  should have disabled it but I can still see aswdatascan enumerating files :-( .

I tried rename aswdatascan but without this dll avast UI process doesnt star.
Sorry I dont have any ideas or workarounds how to disable it. I will try to ask aswdatascan developers to advice something better than changing settings in  avast5.ini.

I might know it would be a difficult one to fix - whenever I get any sort of problem, it's usually something really unusual and hard to solve!  ::)

If you want to fix the problem, tried to use old version of Avast AV.

Since informed many times about that issue in a long long time ago,
I think Avast Product Manager does not care about it.
just produces a bug and bulky products continuously.
Avast team seems so happy for doing that...............   :( :( :( :( :(

I've alerted Avast (kwiq) but this is the weekend. :)

Bonjour,
J'ai parcouru la totalité des messages de votre sujet afin de trouver une solution pour que AvastUI arrêté d'utiliser en permanence mon processeur a plus de 90%.
Mon problème est identique en tout points à celui que vous décrivez.
J'ai essayé de nombreuses manipulationsont pour y remédier,  mais rien à faire.
Tout rentre dans l'ordre quand je desinstalle Avast, mais cela recommence immédiatement après réinstallation.
J'ai comme vous un autre ordinateur avec la même configuration XP ou Avast fonctionne correctement.
Depuis, Avez vous résolu votre problème?
Cordialement
Bernie

He's also posting in a 2 year old thread. Time to start your own thread and explain your problem.
