How do i get rid of this facebook virus?

[Green...L]

Somehow on my facebook page even when i'm offline it is posting links to people on my chat saying that they should check out this link of my cousin dancing or i got a gucci bag or just a bunch of random stuff. I'm not doing this and i don't know how to stop it because it just posts it to random people. Is there anyway to stop or get rid of this?! Please help

Change your password. That's worked for me twice.

Change your password and that will pretty much take care of it. If that doesn't work I recommend disabling that account and get a new one.

Just ignored about it or if this keep on bothering and worrying you just change your password surely it will work.

Install an anti-virus software & have it scan your computer for virus'. Theres a possibility that some could had hacked into your computer, so I would recommend you to re-change your password.
