New to the forum and I have a question

Everytime I try to go to yahoo.com com I get this Welcome to nginx! Message and I was wondering could anyone help me with this. Thanks Andy

Do you think this is after a recent malware infection?

HI
I have an eMac computer someone gave me. It has an os x operating system but it does not
have adope flash. I am trying to find snow leopard software so I can download it for free. I want
to play facebook games with this eMac computer. Is this computer to old to use to play games
that need adope flash.
Please let me know.
Thank You!
