Net connection data transfer

Hi,

Here is a scenario:
I access a java ranch forum. Click on one of my posts and the coderanch page with my post thread loads completely.

Now, I am not accessing any other site at this time.
Even though the page has loaded completely after some time my net connection starts showing data transfer (i.e. upload and download) and it keeps on going.

This happens when I am accessing other sites too after their page has completely loaded.

What could be the reason for this?
Is there anything on windows to find out what is being sent and received during this datatransfer period? and
Is there anything to avoid this happening?
As this is leading to unnecessary bandwith usage, as I am paying for limited data access per month.

Turn off all the autoupdates you can find. Note that some software can't be used if you don't allow it to autoupdate. (I think Google Earth is one ... not too sure though)

Also invest your limited bandwidth in freshly updating your antivirus and do a full system scan.

Hi Darryl,
Thanks a lot for the for the reply.
I had earlier turned of windows updates and now will search for other software which try to autoupdate.
Also will get the system scanned.
Thanks again.

Also I am trying to reduce my bandwidth usage by disabling show pictures in IExplore and also in Google Chrome.
Will this too reduce my bandwith usage? Will it stop images coming from the websites?

Firefox has a feature where it will "prefetch" links on a page. I'm not sure if IE and Chrome have the same.

Thanks Joe,

So one should disable prefetching if using firefox.
Currently I am using google chrome and IE.
