Talking Trojan taunts victims
Malware authors have developed a talking Trojan capable of taunting its victims even as it goes about its work trashing their PCs.

The BotVoice-A Trojan (http://www.pandasoftware.com/com/virus_info/encyclopedia/overview.aspx?idvirus=166596&sitepanda=empresas) informs victims that their Windows PCs have been infected as it deletes files. The malware uses Windows text reader to play the following message:

You has been infected I repeat You has been infected and your system files has been deletes. Sorry. Have a Nice Day and bye bye.
