I don't know if your Portuguese is any better than mine - it would be difficult for it to be worse - but these two posts suggest that it is some form of malware. I don't think it has anything to do with the doubtless totally innocent Mrs Diebold, a physiotherapist of Warsaw, NY, USA. You seem to have dodged the bullet on this one
However keep an eye on your situation, and if you have cause to believe you may be suffering a malware infection start a topic in the 'Am I infected' section of BC.
