I heard that some bad guys use packet analysis tools to monitor data sent out from my computer. How can I be protected from this?
This is quite a generic question. Maybe you could tell us if you are using a public/private computer, and public/private network... Anyways, you can't be protected from this... anybody in the position to see your traffic will be able to see it... You can make it encrypted using an anonymizer (possibily supporting OpenVPN). Search threads in this subforum and you will find million of topics about this.
