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.
