Title: [SOLVED] Internet Speed Degradation with avast 7
Post by: MayuraDeSilva on February 24, 2012, 06:51:45 PM
Hi Guys,

Does anyone experience internet speed degradation with avast IS 7? For me, it takes more time to load web sites than it was used to be with avast version 6. However avast 7 file real-time scanning is efficient than earlier one.

Cheers...

Well, difficult to say and to troubleshoot.
Hope someone more experienced in networking issues come here to help.

Hi Tech,

If you don't mind, can you tell me is there anyone you know who can help me on this? :) 'Cause problem still persisting. Or do you think I should change to version 6?

Cheers...

try closing web shield and then try again, tell us if the problem has been solved when web shield is off.
don't forget to run it back after you finish.

Not to generate any kind of problems.. but i had MSE and everything okay, downloaded the lastest version and my internet, at leasy Google Chrome, slowed a 50%

there's been browsing issues (slowness) with some builds during the beta phase, solved now... at least here I can tell that any network operation runs as fast as possible, ie just as fast as it would be if Avast wasn't installed at all. For those experiencing problems, either wait for an Avast dev to post here and troubleshoot the issue with you, or do a clean install of V7.

Thanks mate :) Tried 'em already. But it still happens.

Thanks mate :) But I love avast and with my experiences it beats all... (And I'm using avast IS...)

Please do, and report back if that has any effect on the network speed.I don't recall any new feature in v7 that could influence this in any way...

Thanks

Hi VLK,

I just installed AIS version 6 and checked browsing speed on my browser. Whoa... Unfortunately now it seems v6 have the same problem. I had v6 before installing v7 and it wasn't sluggy this much. But after installing and uninstalling v7, now v6 got the same effect on it.

Any suggestions?

Thanks...

Which programs are being running in the backgroud?
Can you check changing OpenDNS to Automatic in your network settings help?
Title: Re: Internet Speed Degradation with avast 7
Post by: MayuraDeSilva on February 28, 2012, 09:14:31 AM
Hi Tech,

I just changed to DNS settings to Automatic. But it doesn't seem resolve my problem mate.

I have these programs running on background (in addition to avast):

- Windows Firewall
- TeamViewer
- Networx
- OpenDNS
- Google Talk

And I think it's better to state this here. When avast 7 is in beta phase I have installed it on my PC and got this problem after installation. See ~ http://forum.avast.com/index.php?topic=93092.0. I hope it might give any clue.

Thanks...

Same troubel here. Upgraded my speed recently  from 25 to 50Mb.
Without Avast 7  50Mb, with Avast activated about 30Mb.

Was same with Avast 6.

Yey... SOLVED... Thanks AdrianH :) Many thanks to you... Your tip works perfect. I have set Windows Firewall settings to defaults and now avast rockz... I've installed avast version 7 and it works smart too.

Thanks for all who contributed here guys... :)

I wonder how "resetting Windows Firewall" would improve your internet bandwidth. I mean, either the firewall allows you to connect (according to its rules), or not, but it doesn't improve (or degrade) the speed.

I'm glad anyway you solve it.

Well I have a BT Infinity connection that is a theoretical maximum of 40Mbps download and 2.0Mbps upload (limitation for the account I have).

Given that this is a Fibre To The Cabinet, fibre optic cable to the local street cabinet and then copper cable for that last part (telephone connection) to the home. So some degradation happens for the copper cable from that theoretical maximum, plus the usual degradation as the number of hops in the connection.

I use speedtest.net to periodically check my speeds and in all of the time I have had broadband (only 15 months) I have found it close to my theoretical maximum. These tests run with and without the web shield enabled and in all honesty I find little difference between the two, in fact at times the connection/download speed is faster with the web shield enabled.

I have run a quick test with the web shield enabled and on three different servers and broadly the results are the same (see image), why two of them don't report the upload speed but they too have always be around 1.6-7Mbps.

@david yeah ... I still remember posting about huge differences on speedtest with web shield on and web shield off. This affects exclusively connections above 50Mb/s ... and the issue was confirmed by VLK ;)

Hi David,

(a bit OT) Wow! I remember for years you had dial-up.  What a jump in speed!

I'm aware of the speeds in excess of 50Mbps, but this is reported as 50Mbps connection by jan_e not exceeding 50Mbps.

Same troubel here. Upgraded my speed recently  from 25 to 50Mb.
Without Avast 7  50Mb, with Avast activated about 30Mb.

Was same with Avast 6.

My point is that I see no difference between avast6 and avast7 and as Vlk mentioned "I don't recall any new feature in v7 that could influence this in any way..."

@chocholo  ;D

 ... unfortunately I can't test that anymore, I had a 100Mb/s connection for a couple of years ... , not the case anymore temporarily. I remember that speeds on speedtest were maxing at 37/40 with the web shield on, while I was reaching 80/85 without the shield.

I had the same issue with one of the betas where the install was affected by Windows Firewall coming on. With v7 onboard I found the internet was very slow. Explorer and programs were also very slow to start. I turned off the Windows Firewall and the issues were gone.

I did post this previously, there is obviously some conflict with previous rules, the scond beta I saw the same thing and returned Win Firewall to defaults and the result was that the speed issues were gone.

I don't know exactly mate, but there wasn't any problem with my internet connection before upgrade into version 7. I mean, it takes more time to load web pages. Simply I have to wait 10 seconds or more to view Google homepage.  After installing avast 7, it started. I've reinstalled version 7 few times. Then I've reverted back to version 6 as I have no option left and VLK asked me to report it back. But the degradation was there even after reverting back. And @ last I've restored Windows FW settings to defaults as AdrianH asked me to. Since then I haven't experience any degradation @ all, even after installing version 7 again :) However version 7 has improvement in browsing speed over version 6 as I feel now. Further I see improvement in my startup/boot time too. I don't know the reason, but everything back to perfect after resetting Windows FW. It could be any misconfiguration or FW service problem, isn't it?

Cheers...

The conflict/issue /problem occured during the upgrade, chaging the Win Firewall settings back to default cleared the issue.

off topic: no need to worry too much, 4G is coming ;D ... for those aware of upcoming available bandwidth when and where 4G will be deployed, you won't even need a home connection anymore. You'll use - like you already can - your phone as a modem, and connect anything to it with crazy speeds.

nope, 4G will be cheaper than 3G to provide (for ISPs/mobile providers at least...) ... well from what I read.

You only need to look at existing UK prices for data packages and they aren't going to kill that cash cow any time soon.

The other issue is 4G is at least a year away in the UK (some limited trials ongoing) and longer before the infrastructure covers a high % of the country/users. There is meant to be a beefing up of 3.5G in the interim period. Where I live 3G isn't an option it still doesn't have good coverage.

We've had 4G here for two years now with vividwireless which i was using but in the new area that iv moved to it is still very patchy but there plan prices are outstanding, half the price of 3G. Telstra have also started up there 4G service but unless your within 5 km's of the city central you wont recieve it.

I am having difficulties locating the article, but any area can get fiber... thats real internet that is at the low end of its possible speeds.  The trick, as in my state (may vary in other countries), is to from a co-op innatative.  Get your neighborhood involved as well as participating in any township meeting concering this.  This is the age of the people and the internet is REALLY playing a key role in that.  If I can find the link to the article on forming a co-op to increase fiber/bandwitdh.  Ill Pm ya.  Its great knowledge... and knowledge is REAL power!

Gee I just tested at Speedtest and my best was 24.9 megs down and 3.1 up. That's real close to the max given by Charter Cable though. We have the lowest priced plan available which 5 years ago was only giving 384mb (that's megabytes and 48kb/s) down. They have increased speeds about 5 times now without changing the pricing. The first hike was to 1.5 megs down, then 3, then 5, then 15, and now 25 max.

 My best ping was 45 but the best speed was from Towerstream in New York City which is 300 miles away. When I play World of Warcraft, my latency hovers just over 100ms but the server I connect to is in California so that's not bad.

Oh yeah, web shield on or off makes no difference whatsoever.

Telstra owns all the underground telephone and internet lines here in australia, other companys such as Optus, Virgin, Vodafone pay to rent Telstras lines and being that Telstra has no lines in this area and there probably not going to do it either as there pushing for everyone who lives in these new areas to go wireless broadband so unless i can come up with millions of dollars then i dont think im getting a fixed line connection ;)
