on, most of the time the computer is setting idle - but this activity
just goes on and on. I am running WinXP with all updates, I have a
Local Area Network to also link my laptop to the network via a Linksys
4-Port Router which I have used for quite some time. As I said, this
activity just started in the last couple of days and I cannot figure
out what is causing it or how to fix it.

I have the latest version of Norton Antivirus 2012 running, but have
been using this antivirus program for a number of years without this
problem.


Measured where? At the router or at your computer?

If the activity is at your computer, have you tried to monitor what is
generating the traffic and to where it is going? SysInternals' TCPview
will show you what processes have connections. You can probably
configured it to hide unconnected endpoints (they have unbound yet).
Nirsoft has their SmartSniff and SocketSniff utilities to let you know
what network traffic is received or sent from your computer.
SocketSniff lets you monitor the network traffic for a selected process,
so use TCPview to see which processes have network connections to then
choose one, or more, to monitor with SocketSniff. SmartSniff is a
packet sniffer that lets you monitor all your network traffic. Another
popular packet sniffer is Wireshark. There are lots of network monitor
utilities available at the download sites (download.com, softpedia.com).

If your router has logging, you could turn it on to see to where all
your intranet hosts are connecting. Have you enabled the security
settings inside the router to make sure your neighbors or roaming
hackers aren't using your router? "Linksys 4-port router" tells no one
what you actually have. That doesn't specify a particular model for
anyone, including you, to go read its online manual to find out what
security features it provides.

Do you have UPnP service enabled (http://en.wikipedia.org/wiki/Upnp)?
Is SSDP (http://en.wikipedia.org/wiki/Simple_...overy_Protocol)
service disabled? If not, why not? What hosts or network nodes do you
have that actually support it? What hardware, if any, have you added in
the last few days?

How many wifi nodes, if any, are in your intranet? If none, did you
leave the Wireless Zero Configuration service enabled? For info, see
http://en.wikipedia.org/wiki/Wireles..._Configuration. Do you even
need it if you do have wireless nodes?


Ak, let me try to take a look at what you offered. The Linksys router
is the BEFSR41 model. I'll start by trying SysInternals' TCPview and
go from there.
