Weird notifications popping up on desktop. Maybe a virus?

Some weird notifications are popping up on my Ubuntu that I use just for college. For example:

Facebook 1 new private message

Now... I haven't used facebook for 4 years and I really don't know why I'd get this notification on my desktop. I'm afraid I've got some kind of "virus". How can I know what's that? And what should I do to get rid of it?
