No quasars are thought to be massive black holes that formed in the center of protogalaxies that give off energy as they assimilate gas clouds around them.

Quasars are the extremely bright and active centres of galaxies extremely far away. They're so bright that in many cases the quasar is all we can see - the rest of the host galaxy is so faint we don't see it (or only see a small blur in some very sensitive instruments).
Binary star systems are much smaller and closer to home - they are 2 stars orbiting a common centre of gravity and are thought to be fairly common (of the 59 stars in our "neighbourhood" over half are part of multiple star systems).
