Help! Facebook Hacker!?

[Kiera]

I just went onto my facebook account and I tried to log in and it rejected my password more than once. I had my password reset so I could log into my account only to find that "i" had posted things like :check out this cool advertisement or I love this article you should read it, on at least 20 people's walls. I was wondering if anyone knows how to prevent this hacking and if changing/reseting my password should prevent from further hacking.
thanks!

â–ºMake your account private.
â–ºDon't tell anyone your password.
â–ºNever make such easy password (such as 123 abc (lol!)).
â–ºNever give strangers your private informations, including people you really hate.

Along with what the first person up there said, you should NEVER NEVER follow links that are sent your email inbox that claim to be from Facebook or friends on facebook. Type in facebook's homepage url to log in and go from there. Some links look authentic, but there are minor differences between real ones and fake ones.
