Friends, I don't have time right this moment to explain and link, but I will post a more complete article later today.
WARNING: the IRS don't send no stinking emails to nobody!
DO NOT open any email, pretending to be from the IRS [dot] gov
This is a phishing scam. I got one yesterday. It talks of a refund, gives almost exact amount (HOW????), then says that dopey, ungeeky "click here" shit that no real web guy would use as link wording.
DO NOT "click here" in that email, which you must not open to begin with.
