Guys, I have ubuntu 10.10 in my pc. Recently when I connected to internet (via my phone) i saw a LOT of traffic going out and also coming to my computer(i have a third party app to monitor the traffic). It starts instantly when i connected and i didn't open any application (not even updates). The worst thing is that this traffic is not monitored in some apps(i can say them trustworthy apps like google desktop gadgets). The most interesting thing is when i tried to identify the app doing this by stopping each processes in process monitor one by one. I saw that when i stopped pulseaudio, the traffic stopped slowly after a while. Now i usually stop it before connecting to the internet. But it causes problems with audio and video. I doubt this is a virus or a rootkit(oh god, dont be so). So i need help with this. Can anyone help me guys? (I am not an expert in linux but,kinda of a newbie.)
