There are many things you can do to prevent your account from being hacked.
1. Make a password that is somewhat complicated, but one that you can remember
also, you may want to change it every few months
2. Set recovery questions
3. Register your email (Thanks to Jackdekilla for adding this)
4. Make a pin* (super important)
Put all valuable items in the bank before logging out (Thanks to Jagex for adding this)
5. Don't log onto fake sites
6. You may want to run frequent virus checks
7. Never use your exact username and password combination on any other site
I may have missed several thing, but feel free to add on.
Happy Runescape playing
