Avast Possibly using a lot of Internet Bandwidth

Recently I have been experiencing a little tricky internet speed so I have installed an bandwidth monitoring freeware called NetWorx http://www.softperfect.com/products/networx/manual/?lang=English

I Installed the app on Tuesday, ‎July ‎9, ‎2013, ‏‎7:22:08 PM, so take it as the start point

Avast Internet Bandwidth usage According to NetWorx
Period 9 July 2013 TO 29 July 2013 (21 Days)
Total: 4,28 GB
Download: 4,22 GB
Upload: 55,3 MB
That makes like 200+ MB per day.

Period 9 July 2013 TO 1 August 2013 10:40 AM(24 Days, if count today as a full day)
Total: 6,41 GB
Download: 6,32 GB
Upload: 89,6 MB
That makes like 270+ MB per day.

Is This Normal?
Personally, I don’t think so…

avast! acts as a local proxy, so all traffic runs trough avastsvc.exe, that’s normal.

I wanted to believe it so but I wonder why Chrome and some other applications have far more data usage than Avast.
I mean if Avast is acting as local proxy or such and all the traffic is passing through avast, then it should be more like

Chrome: 10 GB
Firefox: 4 GB
ABCD: 2 GB
GHJKL: 2 GB

Avast: 18 GB

In fact I just forgot to mention that I have configured Nerworx to ignore Local traffic, as is shown in following page:
http://www.softperfect.com/products/networx/manual/options_main.htm

at the bottom of the dialog box screenshot shown at this page, it says Ignore local traffic within the LAN, I have it checked. Hence it doesn’t counts if transfer files within my LAN or I use Windows RDP client etc.

Say, Avast is acting as proxy, I think, all data should be attributed to Avast, since avast is sending/ receiving all the data from internet and my all applications are just using the data from a local proxy, which shouldn’t count.

It is confusing

Sorry, can’t help you with NetWorx. I don’t use it.
For an in depth analysis you could try Wireshark.

Vielen Dank für Ihr Antwort überhaupt.

It seems to me that Avast does act as local proxy server but perhaps when files are larger than a specific size, it let them come/ go directly, I don’t know, I am just saying.

Like for example

  • when I watch a video on youtube, it lets the streaming go direct.
  • when file is larger than 5 MB*, it lets it go directly
  • for certain fiile type, it lets them go directly
  • It monitors some specific ports but not all
  • 5 MB is just an example

Having said all that, I want to hear what some geeks says, and yes I am concerned about Avast’s this much data consumption.

Bitteschön.
