avast acts (by design) as a local proxy.

my bandwith has always been around 700MB a day, and now it is 3400MB
so today I find out that avast is uploading heavy, and that since june10th
so why is this happening now.

Avast is not the cause of this.


Can you give me your applied internet speed?
Download and upload?


I have problems with netlimiter pro. I dont trust that software.



You can test your connection using speedtest.net

Disable avast and test speedtest clicking the server location of your applied internet connection.

If the result of speedtest.net is not really the speed result of the applied connections of you paid then their is a problem with your internet subscriber.

windows firewall

windows xp sp3

XP FW is quite weak, I suggest to use another one.

speed is normal
upload 1.44 mbs
download 28 mbs

someone on another forum told me that it could be virus hiding in avast, so it can't be noticed when scanning

strange thing is, when I disable avast, my bandwith is not rising

Did you try using speedtest.net website?

Is that the result?

If so..

Then try again enabling avast and use speedtest.net

See if the upload and download is the same.

The problem is in Netlimiter which wrong result.

Actually in my experience using Netlimiter i have also plenty of wrong result upload and downloads.

Dont trust that software result.

it is not solved, since my bandwith is still growing fast, and right now the only problem I see is avast.

Did you try calling your internet subscriber?

Also try remove netlimiter.

Which version of avast are you using..??
Where did you download it..??
You can test your avastSvc.exe at VT. (virustotal.com)
Also consider Genesis' last reply.

Wait is this connection stand alone?
Title: Re: avast uploading like crazy, using all my bandwith
Post by: olifant on June 19, 2011, 03:30:42 PM
think so

just found out that when I close my browser "msn-explorer", avast isn't uploading anymore
could it be that the problem is in msn-explorer

If data is uploaded there, yes.

"msn explorer" combines a browser with "Live" features (hotmail, live messanger...). This means that there "must" be some bandwith constantly used, even if you are not directly using it (you are not currently chatting, but the system needs to be active anyway).

Avast "may" be checking the data being transferred, but Avast itself is not generating the transfer.

BTW, to test your bandwith with speedtest.net, you should "exit" any "live" service, any chat method, any social communications, any browser, any FTP, any "toolbar"... The only active connection should be one simple plain web browser window with the speedtest.net site on one only tab. Please note that "exit" is not the same as "minimize" nor "close".

think I found it.  I deleted avast and now all upload is going on msn-explorer.  so something or someone is gone into msn-explorer.  I deleted the program and installed it again, but the upload keep going on

so I may have to stop using msn-explorer

so a big sorry to avast for thinking that the problem was in avast

Does the msn explorer with all that 'live stuff' include an online backup/sync?

I don't think this person is complaining about speed. They are complaining that something is using all bandwidth. It looks like avast to them. Since avast is the local proxy, then there might be a malware infection using all that bandwidth.

Post by: olifant on June 19, 2011, 10:20:08 PM
that is right, it is not the speed but the banduse
well, I found out that it is comming from msn-explorer, I see all other ip's who are downloading
and because avast is checking all traffic I first tought it was avast, but it was avast tracking all the traffic from other people who somehow are using my bandwith with msn-explorer.
just don't know how thay are doing it, so I can't stop it.  only thing I can do is not open msn-explorer, and the traffic stops
