Comprehensive Account Security
This is going to be a long read, so if you're not going to read it all and you're having trouble, look at the issue diagnosis post. This can be found here. If you want a rough overview, it might be a good idea to look at the index post here.
Your RuneScape account is hunted by hijackers, day in day out. They use all sorts to try and gain access, ranging from giveaways to downloads to finding personal information.
If you've been hijacked it is more than likely either due to being phished, either by email, another website, or private message - or if you've downloaded a program which steals information or grants the hijacker access to your computer.
Something people do way too much is assume that their computer is clean, their email is safe, and that it must have been something else entirely. They believe that they've done absolutely nothing leading to their hijacking. I'm sorry to burst your bubble but that doesn't really happen. There's always a reason and a cause.
Targeted hijackings are VERY rare, so you should NEVER look at them as the most likely scenario, until you've reviewed all the other options in this thread. Doing so means you're ignoring the actual cause, which could be anything from malware to poor email security to a reused pass.word.
This covers everything, from phishing to malicious downloads, to targeted hijackings. It includes computer security, things to look out for, and how to diagnose the issue. More importantly, it will provide you with the information you should know, so you can keep your account secure.
