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 informs victims that their Windows PCs have been infected as it deletes files. The malware uses Windows text reader to play the following message:

The comments are continuously deleted as the Trojan attempts to delete the entire content of the computer's hard disk, according to an analysis of the malware by anti-virus firm Panda Software.

Even if BotVoice-A only deletes a portion of files it can still render Windows PCs unusable. Changes the malware makes to the Windows registry mean that installed programs will fail to run. BotVoice-A Trojan also disables Windows registry editor, making the process of undoing these changes doubly difficult.

The Trojan spreads via a variety of means, such as by exploiting vulnerabilities to infect visitors to infected websites and by posing on media files on P2P networks. ®
