My FB keeps sending out spam?!?

[Kenneth]

This has happened once before, and it was my fault for clicking on it. It sent out spam to all my friends. After about a week or two, it stopped. It's been a month now, and I've made sure not to click on spam, and barely go on FB at all. But now, it just randomly started posting spam. Not even regular spam, it posted a picture of spam, and tagged all my friends in it. Why is this happening? I didn't click on anything. Did I get hacked by some sort of spam program or something? Because when I went on, I had to log in again, which is strange because it's set to automatic log in. Please help,

It sounds like a virus. You must delete it:

Also, change your password.

change your password straightaway to something unique, I usually mix numbers, letters and characters such as $ and * (star), never have facebook set to automatic login and don't let anyone else know your password, please don't use easy passwords such as pets names.

Log in to facebook and go to the gear located at the top right of your facebook page, go to Account Settings, and on the left side at the top click on Security. At the bottom you will see Active Sessions, if it says logged in from current session and 1 other, click on the the other open session and click Close.

you should only be logged in from one location at a time, if the spam still continues, notify facebook by clicking on the drop down icon next to the spam post.

disable all of your apps to see if that helps

another possibility is that you installed a browser extension that is doing it with your open facebook cookie
