Should my PC be sending and receiving data onto/from the internet on its own?

I think I might have some sort of mal-ware on my computer. The reason
for this is that my anti-virus software (AVG free 7) has recently
found and deleted (I think) some viruses all of which had 'Trojan
horse downloader' in part of their name and since then my MSIE6
browser has been slightly odd, for example when I click on its icon to
launch MSIE6 and my computer connects to the internet over its dial-up
connection the MSIE browser window takes a lot longer to appear then
it used to.

But my real concern and question is that I have noticed, when I look
at my Internet connection status dialogue box, that data is being sent
even though I have only one web-page up and it has long since finished
downloading, is this a sign of mal-ware that is sending info and or
files from my computer to another computer over my internet connection
or could it be some innocent process going on in the background?

Any help very much appreciated.

There's your problem. As a user you shouldn't be able to run MSIE at all.

It depends on how many sites it's connected to and what the sites are.
When you access a web page, you are not just accessing that server, but
any servers that provide information to that page.  For example, you may
be on, but there are other servers that are providing
images, advertisements, etc.  One example is  If you look
at your connections, you are not only accessing, but also,,, and others. In turn, you will show
multiple connections to all of these servers, no matter which browser
you are using.  At the same time, you might want to run some Whois
checks on the sites shown to make sure who is is you are connected to,
especially if there is data being sent back and forth.  I would also
suggest doing some scans with some other products (such as
Superantispyware, online Kaspersky scan, online Panda scan, etc) to see
if they find any malware on your system.  Also, if the IP's are in the
following ranges, you might have reason for concern:, - - many of these are
hacker/crack/spam sites and could be a sign of a compromised system.

Would you like to explain what brilliant observation that's supposed to
be?  I'm guessing you're bashing APNIC (Asia Pacific region, from
Afghanistan East about to Pitcairn Island, excluding the former Soviet
Union). If that's the case, your list is wildly inaccurate. APNIC has
allocated IP addresses in the following ranges:

[compton ~]$ zcat APNIC.gz | cut -d' ' -f2 | cut -d'.' -f1 | sort -un |
58      123     131     140     149     156     163     170     211
59      124     132     141     150     157     164     192     218
60      125     134     143     151     158     165     196     219
61      126     136     144     152     159     166     198     220
116     128     137     146     153     160     167     202     221
121     129     138     147     154     161     168     203     222
122     130     139     148     155     162     169     210
[compton ~]$

That's the first digit of the IP quad, but before you go blocking those
you should realize that IP addresses are not arranged in neat lines of
order for your convenience. For example, - is
allocated to the following countries:

[compton ~]$ zgrep -h ' 128.' [ALR]* | cut -d' ' -f1 | sort -u | column
AU      CA      DE      EU      FR      GR      KR      PR      US
BE      CH      DK      FI      GB      IT      NL      SI      ZA
[compton ~]$
