Why is Facebook liking pages on its own?

[Jess]

I don't use any of the apps on Facebook, I don't click on the ad links from the side, and I've changed my password and privacy settings a couple of times. Does anyone have any idea why it's doing this or how to stop it?

when you first got facebook you may of been overwhelmed and clicked an app and now not remember it if you log onto facebook and on the left side there should be an area named apps and you can delete those

its not likeing pages on its own somebody is hacking your account since you tried privacy settings and as well as changed your password i would advise you to check your app list make sure you dont have any unathorized apps on your account if you have any remove them if you dont have any of those than contact facebook at the help center http://www.facebook.com/help
