Title: Avast 5.0 conflict with video (youtube)
Post by: Falcon on January 23, 2010, 11:44:05 AM
Hi,

I installed Avast 5.0 and since this installation, problems viewing videos on youtube, Daily motion,.... The video was slow and I had problem with the sound. I deactivated Avast for 10 minutes and everything works well.

I am using Firefox 3.6 and Avast 5.0 with Windows 7.

I think the Web shield is not optimized and is consumming a lot of ressources.

Hope a mature version of Avast 5 will appear soon.

Regards

Surprisingly, it works fine in mine.

Did you update from avast! v.4 to v.5? If yes, then I suggest a clean install instead.

Good luck getting any help on this. I posted about a week ago in the beta forum and got no answer. I had to switch to a different AV until they resolve this issue.

I have the same problem with youtube,dailymotion,etc.It happens with firefox,expolorer,and opera.It is clearly caused by avast 5.I uninstalled 4.8 with revo uninsatller and did a fresh install of Avast 5.0.377.This video/audio choppy problem is my only issue so far but it's a pretty big one.i use ccleaner,then it's fine for a bit,but the problem comes back.I don't think making exclusions for site like youtube or dfailymotion makes any sense at all.Where's the protection then in the future?Please help me out here.I'm not the only one with this issue

I'm using Avast5 AV Free on Win7 64 bit, FX 3.6, HD monitor and am having absolutely no problems viewing videos on Youtube.  Have had no problems with Avast5 at all, in fact.  I uninstalled 4.8 in SAFE MODE, rebooted and ran aswclear.exe, rebooted and installed Avast5 in SAFE MODE (to be sure Comodo HIPS didn't prevent a clean install). Rebooted twice, just because I always do after installing a new program.  Only other realtime SW running in normal mode is Comodo FW with D+ enabled.

FWIW, I turned off the Windows Defender built into Win7 before installing Avast5.  Figured two antispywares running  concurrently would NOT be good.

I'm happy that you are not having this problem and I'm sure most do not,but that doesn't really help solve why the problem exists for those affected.It seems to be clearly caused by Avast 5.I never had this with 4.8.
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: buttoni on January 27, 2010, 08:37:21 PM
Did you install your Avast5 in SAFE mode?  That was my reason for posting at all.  If you install in normal mode, sometimes features of your firewall (like the HIPS in Comodo) prevent installers from writing to protected areas of the registry and the program doesn't get "fully" installed properly.  I never install a program without going out to SAFE mode because I KNOW Comodo has botched up some installs for me (specifically Avast 4.8 a couple years ago) for this very reason.

Any of you guys tried the pre-release version 5.0.394? It tries to address several issues concerning the performance during browsing.
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: bobbyboy on January 27, 2010, 11:02:08 PM
Does 5.0.394 solve this problem with youtube,etc.? I'm willing to install it if you think that would help.I have a number of files in my virus chest.What's the best way to handle that if I install  5.0.394.When I installed 5.0.377 I uninstalled 4.8 wih revo uninstaller,using advanced settings,then did a clean install of5.0.377.I did not go into safe mode on uninstall or install.Is that necessary now? It makes me feel that this is still beta testing and not ready for general use.
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: Vlk on January 27, 2010, 11:06:42 PM
- no guarantee the problem will go away, but there is a good chance it will
- in order to keep the files you have in the Virus Chest, don't uninstall the previous version. Just install on top of it
- build 394 is indeed unreleased yet, so it is, in a way, beta testing.

Generally, I don't think it's worth the hassle unless you really like hacking things.

I mean, it's likely the update will officially be release very soon so you can probably wait.

Thanks much
Vlk

Post by: bobbyboy on January 27, 2010, 11:25:29 PM
Thanks,I'll wait till it's officially released.When I do install it,should I do that in safe mode? Also,do I simply update from 5.0.377 or do I download the newer version and install over 5.0.377?
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: Mr.Agent on January 27, 2010, 11:26:43 PM

Is this new version will correct this problem ?

It is very boring to have such a bug. I am thinking about using another AV after more than 5 years with Avast. I have a lot of colleague in the same case and they are now using Antivir.

Please, resolve this bug.

Good luck.

Yes I am having issues with sound and video. Not just with youtube but other apps.

Do you have issues playing music in the background while surfing or doing other tasks?

Seems like it drives the CPU up a lot and it causes the issues.



I'm sure Avast devs will fix the issue, they have a priority in which things get resolved starting with BSODs.

I have noticed 5.0.396 pre-release is better with this. Give it a try.
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: Falcon on January 29, 2010, 09:19:03 PM
I update to 5.0.396 but the problem remains. I don't understand how Alpha and beta tests were conducted to have a so huge bug and not having yet a fix for it...

For me, it is unbelieveable !!!!

Nobody is answering about if the issue will be corrected or not or if the know how to solve it.

Avast 4 was wonderful, Avast 5 is going to decadence. I think we will have to go ahead and serach for another AV or coming back to Avast 4.8.

Very disappointed by this version which doesn't bring anything else usefull comparing to Avast 4.8.
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: 2nd base on January 29, 2010, 10:00:43 PM
no sense going back to 4.8 because it will be obsolete in a few months probably. Reaad the help file that comes with the program because that was actually the biggest help for me. I had the same issues as everyone else on this thread and it APPEARS to be ok now. Although, My computer is a little slower than usual. Cannot open more than three tabs without lag.

Hi,

What did you do to solve this issue ? For me, impossible to solve it. I have no problems with 4.8.

Hello Falcon...Vlk did state that there was going to be no guarantee that the problem with youtube would be going away. However, he also stated there's a good chance it will. I would think it's not at the top of things to correct in this new version at the present time. If there's a way for vlk and his crew to come up with a fix for this, then I trust it will be corrected at some point and time.

Don't run off just yet. He does read this forum, and is visible quite a bit. He's aware of what's happening. Stay close and keep watching.

Hi News,

If VLK said may be this problem will be corrected or may be it will not it means that they don't know how to resolve this issue. This is frightened me. So I imagine that nothing will happen soon.

I have a pentium 4 2.8 Ghz (it's about more than 5 years) but it has a clean install under windows 7 and is very fast ! So it is not a hardware problem. I think there is a memory leak because :

- When I start youtube, I have  a lot of lag
- I stop youtube, Lag is off
- I reactivate Avast, lag is not present immediately, it appears again after some minutes.

Thanks for your help, howver I think I will switch (after 6years) to Antivir or another suite.
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: Jeleal on January 30, 2010, 12:13:02 AM
Just wanted to weigh in here. The lag is also intermittent for me too. One minute all seems fast with a YouTube video running and more than one Firefox tab open, but then a sudden hesitation when clicking bookmarks or a lag when going from one Firefox tab to another.   
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: 2nd base on January 30, 2010, 11:25:40 AM
It's not youtube. Avast! just is not managing memory properly. Every time I think I have a good workaround, it just goes back to being slow.  Other than that, the program actually works. Just cannot watch a video of any kind. Once you attempt that then everything else starts bogging and stuttering. I'll wait and see if it gets addressed before I look elsewhere. It's not loke I spend the whole day watching video's , I just want them to run without fault when I do.

I was having the same problem using windows xp sp3/1gb ram memory/pentium 4 (3.2)/FF3.6/IE8
I update the avast to version 5.0.396 and the problem seems solved .
it's been 1 days my pc is connected and no problem with audio or video on youtube,no problem with interner browser with many tabs open.......... so far
the reputation of avast its falling with this serious problem .
nobody wants to listen music and video with this problems.
I hope they will launch a new version with the fix for this problem soonn,very,very,very,very soon.
I know several people who used avast end are using AVG now.
but I'm sure they will come back to avast when this unbelievable bug is fixed.
FIX THIS DAM BUG....FOR ALL PEOPLE.. PLEASE.. :)

Post by: 2nd base on January 30, 2010, 06:50:41 PM
It's just that it's when one plays a video or listens to music after a while of browsing the internet that the problem is most noticable.It's always there but it takes a while for it to actually do it's damage.Thats when it slows the pc drastically.That's when the bigger issue (which I don't think has truly been addressed ) is apparent.

Everyone keeps thinking the computer is running fine watching videos until an hour or so of browsing and then it begins to wreak havoc on the systems memory causing crappy scrolling, browsing, pages loading for almost a minute a piece, tabs cannot exceed two and a host of other issues that make browsing miserable.The thing still isn't placing notes into my clean email either. It wouldn't be so bad if we could at least get some small bit of information about how these issues are being addressed but that hasn't happened for any of mine yet. Good luck getting any information.

And it's only the browser slowing down, right? Everything else is ok.

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 5.0.396
after 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.

The problem(?) isn't apparent upon a reboot. In fact, at least for me, it doesn't appear until after a bit of browsing. Perhaps an hour or so. I reformatted one more time and downloaded the program from Cnet which was still offering 377 as of this morning and installed in safe mode without incident. The program notified me that a program update was available and it did it's thing. Avast! is actually running rather well as is windows explorer. It's just the browser that turns into a two stroke engine after a bit of browsing. Windows runs perfectly fine though as does Avast!

I don't know what's wrong with it. I  can't even cause a crash to figure it out.

So far disabling the behavior shield stoped the freezing / sound errors that i was getting while watching youtube videos.

Title: Re: Avast 5.0 conflict with video (youtube)
Post by: Jeleal on February 01, 2010, 01:07:38 AM
I thought I had .396 installed , but it was .377.  Since updating to .396 I haven't experienced any YouTube problems. I have a 6 year old Sony VAIO Desktop with Windows XP,  1 GB RAM, and  Pentium 4,  2.40 GHz. I run Avast Free 5.0 with OA++ and have Web Shields activated in both programs and Behavior Shield in Avast running. Every once in a while I see a slight lag when browsing with other tabs open and YouTube Video playing, but I would think this is normal with all shields running.

Title: Re: Avast 5.0 conflict with video (youtube)
Post by: SugarD-x on February 03, 2010, 03:16:32 AM
I can 100% confirm that this has to do with an issue with the shields. I tested this on two computers using the latest version of FireFox and the latest version of Avast 5. One had settings with every single option turned on, set to the highest setting, etc., and the other with default settings. My results are that in general, Avast 5 has issues with one of it's scanners/shields that is scanning the web browser. Both simple and complex pages lag heavily when being checked by Avast 5 before they can finish loading, and the same goes for media such as videos and sounds, as well. Despite the scanner doing it's job very well in the background, it is causing extreme lag and using up way too many resources. In Avast 4, the only issue I ever encountered in regards to a heavy memory usage was when the program was auto-updating in the background. In Avast 5, the previous issue no longer exists, but instead this one does. Avast 5 is an AMAZING program, but at this moment in time, it is filled with too many bugs. I hope the Avast Development Team continues to work around the clock to solve these issues quickly so that their wonderful program does not become a flop. I will continue using it in hopes that this happens, but I cannot vouch for every other user that may get mad and switch at this point, or the ones that will leave after trying it and hitting these issues. Good luck guys. Hope all is well soon. :)

Post by: HCEarwicker on February 04, 2010, 05:38:07 PM
Hi all -

Just a note to confirm what others have said. I've got 5.0.396, and with only 3 tabs open in firefox there's lagging/mouse-sticking as every new page loads. All and any video and sounds also stick horribly - but the problem occurs only when the behaviour shield is on; turn it off and all is as smooth as a baby's bum.

So I have a simple, newbie-style question: If I "permanently" disable the behaviour shield, can I restart it simply by clicking "start" on the behaviour shield control page - at any time? And: how dangerous is it to disable the b. shield for any length of time?

Looking forward to the fix...
Title: Re: Avast 5.0 conflict with video (youtube)
Post by: Vlk on February 04, 2010, 05:47:56 PM
Is this happening also with the latest defs, AND after you reboot the system?
We did quite some changes to the Behavior Shield yesterday evening, hoping it would fix these problems.

Thanks

Hi Vlk,

I'd last rebooted a day or two ago...presumably before you all fixed things.

Having just now rebooted, I'm now delighted to report all's just fine and dandy. Very impressed with the speedy response. Thanks.
