The BotVoice.A Trojan uses the Microsoft Windows text reader to play the following: “You have been infected; I repeat you have been infected and your system files have been deleted. Sorry. Have a nice day and bye bye,” according to anti-virus researchers at PandaLabs.
The computer repeats the words, while the malware deletes the content of the computer hard drive.
Even when the Trojan is unable to wipe all files, it may still remove Windows files, which could stop all the programs installed on the machine functioning, PandaLabs warned.
“This is a very peculiar Trojan,” said Luis Corrons, technical director of PandaLabs. “Not only does it delete computer files, it does everything necessary to make it impossible to stop its actions. In cases like this, it is important to prevent the infection, which makes proactive protection techniques, capable of detecting unknown threats, a necessity.”
Researchers said the malware is spreading via a variety of methods, including physical storage devices, such as USB sticks, floppy discs and CD-ROMs, and through visiting websites hosting malicious code and downloads performed by other viruses.
