No, Neither Roblox of Facebook have viruses. People on Facebook do sometimes post links to viruses, and there are scams that exist on Facebook, but there are no viruses on Facebook itself. Roblox does not have viruses either. It does have virus scripts within the game, but those cannot actually harm your computer.
No. Unless you go on links from facebook, but they would have to be really complex viruses.
Facebook in itself cannot give you viruses. However, clicking on the advertisements, or using applications not developed by Facebook or a trusted company potentially can.
No, I scanned it many times and there is no viruses...

yes
Twitter doesn't give any viruses as long as you're careful, facebook is awesome and it doesn't, but Myspace and Bebo gives viruses so becareful.
Yes facebook does have viruses just like most other websites. My computer got a virus that was caused from both facebook and myspace and I had to get a whole new computer.
You can only play Facebook games if you have a Facebook account. :)
No, it is 100% free. Hope this helped!
Facebook itself does not produce games. However, Facebook hosts 'applications', many of which are games.
