Looking at your post history, you seem to fall easily for scams, and you seem to have difficulties keeping your computer malware-free.
Please educate yourself about the safe handling of bitcoins, and don't buy any more unless you know how to keep them secure. Nobody here can get them back to you if you lose them.
In this case, it's most likely a scam, and it's good that you asked before you invested something there (at least I hope you didn't invest anything yet?)
