I am using the tool "Internet Traffic Agent" to monitor my in- and outbound traffic. It shows me clearly that over a period of approx. an hour, some process on my machine is uploading data, about 200–250MB. This seems to me very suspicious.
I have noticed that a data is constantly sent to 255.255.255.255. Is that OK?
In general, how can identify all processes that are sending some kind of data over Internet on Windows 7?
