On my computer with AMD Sempron 1.8 ghz 2g RAM XPsp3 32bit I get 30 mb internet speed with Webshield turned off.
About half that with WS on.
Checked with http://www.speakeasy.net/speedtest/
With my AMD Turion TL60 dual core 2ghz 4g RAM Win 7 64bit I don't experience any slow down.
Connected to same D-Link router, wired connection.
I hope this what you want.

What does the CPU usage chart show when you max out the bandwidth with WebShield enabled? (I mean on the Sempron box). Do you see any peaks in the AvastSvc.exe process?
I realize the Turion has much greater processing power and that's the reason for the difference, but not everyone has computers with the power to compensate for WS's drag on their systems.
Also, if you are experiencing the issues, does it make any difference if you open the avast UI, navigate to Real-time Shields, Web Shield and uncheck the "Scan web (HTTP) traffic" box?

I'm not sure if the speed test thing is really much use :I'm having the same results with 5.5 Mbs in download and 748 Mbs upload (and that differs somewhat from what I had yesterday night at 4.6/748 Mbs) with a A quality line. I think AILWIL should "think" protecting as well old and poor performing computers as well as performant ones. ;)
with "Scan web traffic" disabled my speeds almost double using http://www.speakeasy.net/speedtest/
then almost no difference at all (either disabled or enabled) using http://www.speedtest.net/
then better results with "Scan web traffic" enabled using http://whatismyip.com/speedtest/index.asp than when disabled !!!
Obviously a lot depends on which servers are used and where they are situated geographically but even so imho these tests don't seem to help much with the present question.
@ rhawley1960
avast will not ask you to upgrade in the manner you have said - you must be mean update
If you were asked to reboot then likely the update was a Program update - you will also see that on the page
- you should have program version 5.0.418 (unless you have downloaded Beta which is 5.0. 454)
Edit - sorry screenshot attached now
Please could you provide details of your updated details so forum can help you sort yr problem
Mine are --
engine and defs = 100308-1
program = 5.0.418 (as above)

I still have the same problems browsing and getting mail. I have to stop the Web Sheild to be able to browse after loading a few pages, and I can't use my mail client unless I stop the Mail Sheild.
My connection speed actually went down with WS off but its compromised by having a shared connection through a router.
Forget it, those sites aren't reliable. When you test servers distant from you you can get very different and funny results that more or less make sense. It put doubts on the fundamentals of the thread!!! 8)No lol its about 60 kb for downloads and about 13 kb for uploads also :)
I do notice performance degradation from web shield, but I think it's due to one of my firefox addons - Speed dial. I'm pretty sure that web shield is scanning every page on my speed dial, which is a total of 48 pages. The reason I say that is I sometimes notice upwards of 500 connections in my firewall when I have only 2 tabs open, and sometimes it causes a lag. So i'm thinking it's more a Speed Dial issue than a web shield issue, right?
There is huge difference when talking about SLOWING DOWN WEB SURFING compared to DOWNLOADING DATA FILES.
Web surfing speed is ok.
Your question is badly formulated.
I have Pro AV installed. It goes to all files, when downloading larger than one megabyte files. Of course you have to rule out dial-up connections. You have to have "fast" enough connection when this problem kicks in. Disabling webshield corrects the situation. No problems with other AV's.
gdiloren and others who also have the problem, are you also running uTorrent on your system?Sorry for being late. No, I never used u Torrent or any other P2P. As stated, I find the same slowdown in surfing with WebGuard of Avira than WebShield of AVAST 5. I'm confused as AVIRA works fine on my PC whereas AVAST 5 I was forced to uninstall rapidly for strange behavior (I always use MAXIMUM protection, though!). I'm even more confused when I read reports by others that your software is among the best and works fine ON THEIR computer. ??? It's sure frustrating for me as I used AVAST since ever (1997). I will try to install it again when ever I get more time. Sorry... Hope I could help more. Thank you! ;)
Hi. I upgraded from v4.8 to 5.0 yesterday and was virtually unable to connect to the internet afterwards. I disabled the Web Shield this morning and browsing is back to normal. Unchecking the "Scan web (HTTP) traffic" box did NOT fix the problem.

Most likely, a firewall is blocking AvastSvc.exe process from accessing the Internet then...
@ bobobo
Ask yourself why am I having a problem and many others are not.
Could be your ISP connection type as in DSL vs cable.
Maybe your system specifications would help as well.
How did you do the upgrade from 4.8 to 5.0? There have been some reports in the past of needing to do it in two phases, in spite of it usually working with just the 5.0 installer. Suggest you try the following:
Uninstall current avast! version with add/remove programs
reboot
run the avast! uninstaller in the sticky on this forum
reboot
reinstall 5.0.462
BTW, I also use OA along with Avast! 5, with Avast! excluded in OA, and that seems to work fine. Did you exclude the whole avast! 5 folder and subfolders?
Thank you for the suggestion. I will try that tomorrow (it's nearly midnight here) and let you know how I get on. Appreciated!
I don't think so. I'm using Online Armor firewall and I have Alwil software excluded.Hi. I upgraded from v4.8 to 5.0 yesterday and was virtually unable to connect to the internet afterwards.

Sorry - I think I mis-understood the tone of your message & over-reacted. Please accept my apologies. :-[
I have however noticed a BIG decrease in download speed from my newsgroup server. I would say that newsgroups have very consistent speeds and can be used to test connection speeds.
Anyhow, I noticed that my speeds have gone from 1-1.5 MB (yes, megaBYTES) per second to about half that. I have tried changing settings so that NNTP traffic wouldn't be scanned as vigorously (as I was able to do in 4.8). I was not able to fix the problem. I saw this forum and tried playing with the webshield. I tried turning webshield off, and didn't see any immediate effect (so I turned it back on). I then tried disabling the "Scan http traffic" option. No immediate effect, but in less than 5 min, my newsgroup download speed has returned to normal levels.
Hi tovento, NNTP traffic does not go via HTTP protocol (and so it does not exercise WebShield at all), it uses NNTP instead. This is checked by Mail Shield (Mail and News). Does the speed change when disabling Mail Shield?

Hi Vlk :)
Like I've Said Before...
My speeds do NOT seem to be affected by the Avast 5 webshield 8)
I've never really kept check of my Upload Speed as much as I have my Download Speed :-\
However!
100% Sure... My Download Speed Is The Same As It's Always Been :D
I'm Using...
Broadband
Up To 8Mbps
Netgear - Wirelesss Modem/Router
(http://www.speedtest.net/result/741202112.png) (http://www.speedtest.net)
But I Do Have One Problem :'(
Avast seems to cause my Internet to have minor cut outs at random times ::)
What I Mean...
My little Internet Globe Icon ( Showing Net Connection ) keeps disappearing from the Taskbar.
Opening a browser or web page always brings the Globe Icon and my Internet straight back again.
But It Does get Annoying! >:(
Note: Some days the problem is worse than others ( Almost Seems Like... Definition updates can have a positive or negative effect )
Note: I had exactly the same problem with - Avast 4.8
Note: I know that it's Avast causing the problem.
Because it doesn't happen when Avast is uninstalled :(
Threads where I've talked about this problem...

Thanks! ;)
PS.
A couple of other people have also said they have the same problem as me.
HallyAvast 5 - Rocks! 8)Baby Boy :D Congratulations! ;)
Hi Halley, I think probably better that you see people who provide Internet Globe function as this must be part of an additional feature that would appear to be using much resources if avast updates are causing conflicts when you surfing at 6.45 Mbps. What is the Internet Globe function, and who is it by?

Hally should see guys from Microsoft? Maybe...
Internet Globe is icon for network connections. Hally is using Vista.
:P
Using both at the same time? Silly you :-)
Tried anonther browser? (e.g. Opera)
@Hally:But I'm NOT using both Avast 4.8 & Avast 5 at the same time.
Same with me! It only happens when I use Avast both 4.8 and 5.0! This is the only program on my computer that causes this to happen! I emailed Vlk about this but never got a reply.
Were you able to actually create a profile and log in? That's where the hang occurs. Sorry, I should've been more specific. I know this sounds like a sales pitch but seriously, we're just getting started: the site is totally free and you won't get any junk mail.
Sorry folks, apparently the server was acting up earlier and it was impossible to sign in even if everything was okey-dokey!
I just tried it again: No sign in with shields on, can sign in with shields off. David: I totally understand. You'll just have to take my word for it: Avast is blocking my access, even when the site is in the "exclusions". I saw something out there on the web that mentioned that other Smartfox users have reported problems with the Avast 'Web Shield'.
OK I just went to your site and indeed it hangs on connecting... nothing tells me that it's Avast related, and sorry but I'm not ready to stop the shields to test the behavior of that site.

Nice attitude. ;D
.
Richpowell , to be able to connect you need to enter the global settings>troubleshooting> redirect settings and to delete at HTTP section the use of port 80
could you please respond to my problem please
What is your firewall ?my firewall is windows xp standard firewall
Does it allow avastSvc.exe internet access ?
- If it does delete the entry for it and reconnect to the internet, this should force the firewall to ask permission again.
Hi,
I am a French user.
I used MSE but I had doubts on its reliability.
So, there is only a few days I returned to Avast by installing the free version 5 .
I meet three problems:
- a very clear slowing down of Web surfing although I have no tool to measure it
- 41 false alarms (worm, trj...) resulting of a scan personalized on memory, rootkits
- impossible to select the lines of the report and the button "apply" ineffective
Except for these blocking problems, I find new Avast clear and easy to use, good job.
Best regards
We are on page 11...yep, I noticed the size of this thread was increasing every day :D
Please make sure you have the Update Rollup 1 installed (it's required for avast! 5):

I can see where could get that scjr - but I'm not expert on avast Settings
- there may be conflict in channel, perhaps MS background intelligent Service
and same situation with Redfan, not necessarily will there be conflict - can still be smooth running
btw are you on cable scjr?
Thanks again......but I’d rather go e out web shield since it slows both download & upload by approx 200-300 megabits.
Hi there,
I have been affected by this problem for a very long time (at least since I upgraded to 5) but I have only just recently identified that Avast is causing the problem. When browsing sometimes my web pages take a long time (if ever) to load. I'm not sure if the page content matters or not. Quite often I load up Google, search for something, click on the link (open in new tab) and the browser attempts to connect to the site. Quite often its just sits there spinning its loading graphic displaying "Waiting for [site address]" and displays a blank page (ive experienced this via IE,Chrome and Firefox).
Web speed is fine, if I go to a speed test site, it shows that I have up to 20Mbits. Its just that the pages stall while loading.
A simple test I used to diagnose this:
1. Go to Google and search for some random topic.
2. Open up the first 10 hits in new tabs (middle mouse click)
3. Wait for them to load.
4. Clear the browsing data and cache, change my config and start again.
I found a post saying that adding avast to my firewall exceptions should help. But it didn't. The only thing I have found to help is to turn off the web shield and the network shield.
By the way, I also got a BSOD (PAGE_FAULT_IN_NONPAGED_AREA) on win32k.sys while re enabling the network shield once while testing, I have never seen that before, but it could have been a coincidence.
Without the web and network shields, all pages load completely and quickly.
I don't monitor these forums, but I though't I'd let you know.
I'm using version 5.0.545 on Windows XP Pro.
Also I would like to ask, does WS do some *in the cloud* scan to possibly take advantage of new signatures that may have not yet been released as update ?No. All scannings are local.
