ipblocker, peer guardian, none of that matters if you turn off sharing.
Firstly, you also need to turn off the 'function as a supernode'.

Also, simply turning file sharing off isn't good enough, you must also verify it stays off as there are multiple ways for it to get turned on without you doing so. For example - duster.b virus would automatically turn it on if you became infected.

Just as quick fyi,
