Is this beta flag for real??

Q u o t e:
how can i tell if my account has real beta flag or is a tricky overlay by a hacker? i downloaded beta and didn see anything or access so deleted and now scanning with avg.

While I am unable to speak to the particular e-mail you are referring to, Bogdan, I am pleased to inform you that your account is flagged for the Cataclysm Beta. Feel free to log into Battle.net and download the client.

Enjoy!
