I think I may have a virus on my MacBook?

[Carla]

I can't play any games on Facebook, I can't watch any videos online (Facebook, Youtube, etc.) and I am starting to think that there is a virus on my laptop, I really need the resolution soon.... Can any suggest anything to help?
I have the adobe flash player downloaded... and they are still not working... :/
I have it installed as well.

You don't have the Flash player installed or it's corrupted.
Just so you don't know. Flash player is what plays those Facebook games and the videos online.

also look into getting the appropriate version of Java script (Google)

None of what you have said is a symptom for virus infection.

You need to install (not just download) the latest Flash Player...

There are no MacBook viruses, you can't have one. The few Mac malware items out there have to be downloaded and installed with your admin password. I assume you didn't give some Nigerian Prince your MacBook info?
Try a different browser like Chrome or Firefox. You must have something like Java disabled on your MacBook.
