Facebook virus

Yesterday I received a message from a friend on FB. In this message this is a video named " you are the funny gal in the world". It is a video link. After clicking this video, an unknown software was installed on my PC. I realized that I got a virus. My brother downloaded Anvi Smart Defender to get rid of this virus. And he told me to not go to facebook again because it is facebook that got me this virus. But I really wanna stay with friends on facebook. Will I get virus if I don't click any video on facebook? Is it facebook virus?
