When I installed 6.0.1091 on my other laptop with 512mb, Win XP Pro, Intel Pent 3, 698mhz, My internet speed goes from my 18.0 to 8 to 9.0 When I disabled the 'Web Shield' my speed went up to 18.0
1. What could be the problem.
2. Can I use Avast with 'Web Shield' off?
Thanks in advance.

first thing you have not mentioned avast version in your signature.
2nd-----> It is not advisable to turn off web shield as it eliminates all web threats before your browser even sees them. So its a very important part
-
Important question to ask is how are you coming to this conclusion of your original bandwidth speed and the subsequent decrease?

I went to a speedtest site. When I have 'Web Shield' enabled, my internet speed gets cut in half. I have done multiple tests. When I disable 'Web Shield' my speed goes back to normal.

Ok, thats been talked about here before, and was stated that Avast! is more likely fudging the accuracy of the speed test itself than slowing down your bandwidth. Recommendation for a more accurate result was downloading a large (and safe) file with WebShield on, then try the same DL with WebShield off.
-
Yeah sometimes, the speed goes down. If u have any other secondary antimalware utility running in background..... Check if u r running only avast....

Just make sure File System Shield and Auto SandBox are enabled and you are protected.
Turning Web Shield off, only blocks web protection. Because web malware is effective only when downloaded offline, as long as File System Shield is on, Auto SandBox is enabled and virus definitions are up-to-date, you are protected.
As of network attacks, they do not need to be downloaded offline and a hacker can remotely hack. To stay protected from network attacks, make sure Avast! Network Shield is turned on.
What I did was I kept 'Web Shield' On, but I unchecked 'Scan web (HTTP)traffic' from the 'Web Shield' and now my speed is back to around 18.0 Will that still protect me from the web?

Try not to make that a first recommendation, that should be a last resort only.

No, you more or less turned it off by doing this. Try what I told you....or don't, I guess ::) ;D

I agree.
Download e.g. the AIS installer file from my signature (click on the blue AIS) and take the time the download took.
Turn of WebShield and do the same again.
Any significant time-difference?

weird on your connection, but normal on connections above 50Mb/s, the issue is known. I got it here. Workaround is to use an external download manager that doesn't get the web shield in its way ;)

At this moment, I don't have a large file to download. I also notice it on my web pages, they load slower when 'Web Shield' is on. So, then why does it still say the 'Web Shield' is running even though I unchecked 'Scan web (HTTP) traffic'

What is a external download manager?
-
@RB123 read my post above ::) >>> I'm adding, "normal" browsing cannot be affected obviously, as that doesn't require high bandwidth.
On a side note, I'm still getting 25/30Mb/s with the webshield on while using an integrated download manager, while I get twice as that and above with no web shield, and again, like I said already, use an external download manager >>> the web shield won't interfere with it.

What is a external download manager?
example: Free Download Manager http://www.freedownloadmanager.org/

Yeah, I'm roughly around his advertised speed at 14 Mb, and I lose nowhere near half my bandwidth. ~1 or 2 Mbs is my noticeable impact on a large download.

With 'Web Shield' on, it was about 56sec
With 'Web Shield' off, it was about 1min 40sec
But my web pages still load slower with 'Web Shield' on
-
Ehhh, a little better than the speed test result in terms of loss but still a decent chunk. What kind of page load time differences? Changed any WebShield settings? How long have you had the problem, like would it coincide with any recent updates?
-
doesn't affect video streaming either, as first, the frames are either downloaded as you see them, either cached progressively. And second, the web shield doesn't scan videos (by default) anyway so...
-
Yeah, changed any settings at all?

I had this problem when Avast started with 6.0 actually. No problem with recent updates. After I tried Avast 6.0 and had this problem, I tried Panda Cloud on this laptop with this problem and I didn't have any problems with my speed. But, I like Avast better.
-
Well, bottom line is it should not have noticeable impact on things you are mentioning. Might be you should try a clean re-install if this happened when you updated to ver. 6.
edit; Where's Safesurf, we need one of those fancy canned re-install instructions ;D

It has happened with other 6.0 versions. Like other people have said here, looks like it's a known issue. It's very simple actually, with 'Web Shield' off no problem, with 'Web Shield' on, problem.

Oh, its far too late/early for me to debate this with you ;D
Just know, if you turn it off, its at your own risk. Avast!'s parts are meant to work together, so turning off the WebShield might be akin to making it try to run the
Anti-malware Marathon with its hands tied behind its back. ;)

@Gargamel360 the web shield is a major and quite advanced feature, but it's not the main resident component in Avast. The core resident protection is the file shield, and having just it activated still protects your system pretty well, i.e. the FS doesn't need the web shield to run well ;)

Oh, I don't mean to say he is naked without it. Just shirtless. ;D
Just seems the too easy solution for a problem that shouldn't even be there, plus it isn't the safest option, so I hesitate to recommend it.
-
I don't recommend it, I'm just saying that a system still benefits from the main resident protection in Avast when the web shield is off ;)
-
I forgot to mention, another option that may help to speed up things while downloading (using a browser native downloader), is to deactivate "stream scanning" from the web shield advanced settings. This will prevent the shield from scanning just downloads, while these will still be scanned at disk level by the file shield.

I can vouch that this works, no slow down that I can see, FYI.
That's "intelligent" stream scanning I untick.

So, If i disable 'Web Shield' and visit websites with malware, will Avast still block them? Like I said before, I want to keep Avast, cuz I like it. :)

So, if I go to a bad website, the file shield will still notify me with a pop-up, saying it was blocked?

yes, when it intercepts the threat at disk level (while the web shield intercepts earlier, in memory).

Almost identical speeds for On or Off for me.
You could try and guess which is which, but it wouldn't matter to much.
But for those who want to know.
The top part of the image is wit the web shield on and the bottom with it off.

the issue affects mostly connections above 50Mb/s >>>> see my screen shots again ;)

I thought that Vlk or Igor said at speeds above 100Mbps.
Since the OP's speeds are way lower than even the 50Mbps if that is the limit at which it kicks in. Then there has to be something else in the mix.
When I installed 6.0.1091 on my other laptop with 512mb, Win XP Pro, Intel Pent 3, 698mhz, My internet speed goes from my 18.0 to 8 to 9.0 When I disabled the 'Web Shield' my speed went up to 18.0
I did a test not just on speedtest.net but using the link in Zyndstoff's signature for AIS ( 77,589KB) for a more real world test and downloaded it using Pale Moons internal download function.
I only timed it using the second hand of my desktop clock:
First, with the web shield enabled and it took 10 seconds, I was surprised.
Second, with the web shield disabled and it took 18 seconds, I was even more surprised to find it almost took twice as long.
All of that without resorting to disabling the Use intelligent stream scanning, weird.
-
Apparently Avast! Ubertechnicals get a special prototype Webshield that is also a Web Accelerator? ;D
-
I can't explain it, must be having to suffer for years and years and years of dial-up and average of 52000 Bps before broadband came to the sticks where I live seven months ago.
Three months later I managed to get Fibre to the Cabinet connection (last part copper wire) and a max download of 40Mpps, so very close to its max. So I consider myself very fortunate right now and don't forget my dial-up days.

40 Mb/s is already pretty fast, and yeah, I know where you're coming from ;) ... about the web shield issue, that I can reproduce anytime, I started a thread about it several months ago. Vlk confirmed it like I said for connections above 50Mb/s...and it's been confirmed by other users so... On a side note, I'd like to see Zyndstoff screen shots... ;D
ps: @zyndtoff aka etc..., genuine web shield off and on pics ;) ... and please, in Mb/s, not in MB, probably a typo :)

If I uncheck 'Scan web (HTTP) traffic' and leave the 'Web Shield' running, will it block urls only?

No, it won't do anything...
Net Shield will continue active.

Ok, Thanks.
Also, What happens if i uncheck 'use intelligent stream scanning'
-
If I uncheck 'Scan web (HTTP) traffic' and leave the 'Web Shield' running, will it block urls only?
Well the blocking of URLs by the web shield is only for URLs that you specify. What that option is doing is stopping all scanning for http traffic. However, web shield site blocking, redirects to a local page and is displayed in the browser by the web shield, which should work as you haven't disabled the web shield (and its http redirect, it just isn't scanning http traffic). But I haven't tested that.
So not really sure what you mean by blocking URLs, if that is blocking malicious content in URLs then that would be no.
The network shield blocks known malicious sites.
-
<snip>
Also, What happens if i uncheck 'use intelligent stream scanning'
Basically it works but isn't scanning at a lower level, e.g packet http traffic, instead it would wait until that particular element/page/image/script, etc. is completely received.
This is the lesser of two evils.

Thank you David for your help, on both of my questions above.
-
what's the point of asking the same questions and getting the same answers twice?
-
Well a bit surprising for me... as many people has already reported that their internet speed has decreased while using Web Shield but I tried it on my friend's pc and guess what I got 150% speed when Web shield on and when web shield off its a bit slow... Sorry I forgot to take the screen capture but rather I did the test at least 10 times and every time result was same.......
I know many of you will not agree to this...
Thanks
