My wife's computer, running XP Home, seems to be sending pulses of between five and fifteen KB of data out to the internet every second. (You see a sawtooth curve on the Task Manager.) I suspect some malware, but none of my malware detection programs have found anything. Is there some utility that I can use to find the destination of these packets of data and/or what is sending them?
