Consider the following:
An advanced adversary is targeting you. He has the ability to watch most if not all of your network connections and the ones in the neighbourhood. He is sitting on numerous zero days. He can also follow you physically to whereever he wants and knows generally a lot about you and your habits.
You could of course try to buy new hardware, install some IDS but why? Since you're possibly surveilled all the time it is hard to securely bootstrap a system. You maybe can lower the risk here and there a bit but ultimately you wont approach the security level you like to have. (At least I don't). It would also be hard to get a baseline of what would be considered normal network traffic or application behaviour. In contrast, you would risk even more compromise, waste resources, ...
Is their any point in changing your behaviour? Since they already hacked your system(s) it does not really matter if they do so again. So, what to do? Read a book, get some games to play (offline), join the Foreign Legion?
