Have any of those with this problem enabled the avast! Settings, Basic, Appearance, Use special graphics effects ?
As it says this is 'nicer, but may slow down performance on some systems.'

I don't see any way of disabling the graphs, but surely this wouldn't matter if the avastUI remains minimised or on one of the options that doesn't display a graph, e.g. Summary (not statistics), Scan Computer or Maintenance sections.

That seems to work! I saw 2-5% CPU for AvastUI.exe. I somehow missed that options in settings. Thanks. :)

You're welcome, though that setting is disabled by default I believe.

(special graphics effects turned off) Re: AvastUI.exe hogs CPU!

Good idea, I had the same thought and turning off "special graphics effects" was the 1st thing I tried to no avail. If anyone on the development side of Avast reads this thread, can you answer a couple of questions?

1. What does Avast use to render these graphs? DirectX, OpenGL, Windows GDI? or some form of ActiveX/Flash like another thread mentioned?
2. Can I somehow update this rendering platform? Like getting the latest .NET framework or something?

I would rather not have to uninstall Avast! and use something else.

Thanks...

The statistical graphs use flash, though I don't believe that is what is meant by the "special graphics effects" as the statistical graphs still work without that setting enabled I believe.

Is Flash from Flash v10 plugin or does it come with its own Flash player? I know regular Flash v10 web browser plugin do not run well on that PC. :( Yonatan's post #7 said it wasn't Flash so I am confused.

It uses flash if you have it installed, it doesn't come with its own flash player.
