AvastUI.exe * 32 always uses 25% of cpu's resources.

Hi lanshark4972,
I found 'Dumps of avastui.zip' folder.
It looks like there was DataScan task running in background.
To conffirm it please disable avast self defense for a while and rename  aswDataScan.dll -> aswDataScan.dll.org (C:\Program Files\AVAST Software\Avast\aswDataScan.dll) than enable self defense
and restart Avast UI. 
Let us know if it helped you.
Thank you

You nailed it, kwiq; thanks! I did what you suggested, rebooted, and that rascal avastui is nowhere to be seen. Moving right along: is there any problem with aswDataScan.dll being disabled?

Today:

* AvastUI.exe now runs only 3 seconds or so, then quits with no errors, both at boot and when manually clicked.
* The Avast tray icon then remains but disappears upon mouseover so I have no way to see the UI--if it is running...
* Avastsvc.exe continues to run as a task, but Task Manager shows no cpu usage when I check it.
* AvLaunch.exe does nothing that I can see, and shows as v18.3.3860.0

Questions:

* Is Avast providing me active protection now?
* How do I get to my UI?

Hi lanshark4972,
you can always rename aswDataScan.dll back and see if AvastUI.exe runs.
 start  "c:\Program Files\AVAST Software\Avast\AvastUI.exe"  process.

It seems that AvastUI.exe depends on aswDataScan.dll :-(.
I will ask my workmate how to disable datascan and not break UI.
Thank you

Thank you, kwiq; remember that, in spite of the title of this thread, avastui uses just about 100% of my cpu
, so reenabling aswDataScan.dll doesn't seem like a good idea. Let's hope that your workmate is successful.

as am not using the PC for long time, i am going to remove avast, and will keep my computer use the built-in antivirus, (using windows 10) for 1 month and will reinstall again the avast after they fix this problem ( i hope )

Any news on this one? It is reported that latest Avast 18.5.2342 still has this issue.

I gave up because of Avast's slow responses and lack of a timely solution. I removed Avast and went looking for an antivirus solution that wouldn't eat up the cpu on my XP desktop. I tried and passed on several, including Avast's evil twin, AVG. In the end, I selected and am happy with a free cloud-based AV, whose name I won't divulge because, well, that wouldn't be right...

One of my systems is XP Pro SP3 and I have never experienced this excessive CPU usage.  Obviously I have no idea of your installation (what components, other security based applications, etc.) so I can't test it.  My installations are very minimal the basic security shields and no others.

Be careful of cloud AV protection, as in how does it cater for off-line useage.

Has there been a response to this regarding the aswDataScan.dll file?  I too am experiencing 100%CPU usage on a Windows XP SP3 laptop.

Thanks,

Hi LeifW,
there is an option Enable=1 in DataScan section file: C:\ProgramData\AVAST Software\Avast\avast5.ini
Try to disable self defense and override it to Enable=0
Thank you

I'm interested in why this might effect some XP systems but not others ?

Also, considering AvastUI.exe is meant to be for the control of the UI, why is it apparently (CPU % usage) now involved in a security related function/required file, e.g. the aswDataScan.dll ?
