In order for this not to happen again do the following:
Stop using Windows and MacOSX.
Download and install Fedora F16.
When installing, encrypt the harddrive with a really hard to break password.
Install pidgin and off the record like this: 'yum install pidgin pidgin-otr'
Generate keys and verify them before communicating.
Be _very_ careful if who you usually talks to changes their key, they might have been arrested.
Never ever communicate in the clear.
Using this strategy you will not be immune, rubber-hose-cryptanalysis with still defeat this. Also you can be tracked so your oppresive government can see that you communicate, they will just not be able to read what you are saying. And not using major OSes will keep you away from the most common exploits and trojans.
Also, try to use TOR, HTTPS-everywhere and other good tools.
