Why can't I play pogo game?

I play pogo games a lot, but today I can't. The only thing that happend to my computer is virus, however my bro has reinstall the computer. So the computer is as good as new. Anyway when I click on pogo's game, the web boot me out of the internet. I think this have something to do with JAVA, because when I go to JAVA website, and it do the same thing.
