Guys (especially Falcon), the fact that you're experiencing the problem doesn't necessarily mean that others are experiencing it as well (or what is the prevalence of the issue).
Now, I'd suggest disabling the Behavior Shield and checking if it makes any difference. Ideally, disable it (choose "stop permanently"), reboot, and test. Does the problem go away?
The problem is, we're not quite able to simulate the problem (even on low-end systems).
Thanks

i really recommend The free version of avast 5.0.396after several hours testing this version I dont have any more problem with video or audio using youtube or not,
its fixed for me.
I open several tabs at once (more than 12 tabs) as I listened to music and everything was great..
using FF3.6 end IE8,no slowdowns..
I think who are having problems may have slow processors.
this means: avast need a few more adjustments.
Vlk, thanks...
Falcon.disable all modules and see if the problem stop.
if stop,avast need more adjustments
which programs do you have on your computer ?
avast may conflict with some software.
can be with browsers or drivers.
I think
this is the best antivirus in the world.not exchange avast for another AV,this problem will be fixed soon.
i hope.
