A new kind of malware circulating on the Internet freezes a computer and then asks for a ransom paid through the Western Union Holdings money transfer service.
A sample of the Trojan horse virus was sent to Sophos, a security vendor, said Graham Cluley, senior technology consultant. The malware, which Sophos named Troj/Ransom-A, is one of only a few viruses so far that have asked for a ransom in exchange for releasing control of a computer, Cluley said.
The new Trojan falls into a class of viruses described as "ransomware." The schemes had been seen in Russia, but the first one appeared in English just last month.
Hitting the control, alt, and delete keys will not affect the bug, the virus writer warns. Sophos provides further details at
its Web site.
