too many connections

[stemy]

After browsing the internet for a while, my computer starts downloading and uploading tons of data without any internet progran open (for sure). I installed norton internet security and noticed that while it doesn't happen I have about 20 connections and when it does I have something like 350 (!!!).
I tried blocking each and every connected ip sepperatly but it seems futile.
plus, it totally paralyzes my internet connection and when I think I disconnected norton still shows me 350 active (and working hard) connections.
Does anybody have any ideas ??

The reason for this activity, may be trivial such as self uptdating some programs or even very dangerous because of a Trojan horse is working or something like that. I can not really tell you something about the true reason from here.

But what i can tell you: Surfing without a firewall and Virusscanner is like playing russian roulette.

go to grc.com an use the probe my ports to see what open ports you have.

use spybot

http://security.kolla.de/

to check for trojans

and do

http://security.symantec.com/

there's an online virus scanner.
