This is not a joke, a Swine Flu Virus hit Japan. However, the casualties are computers.
Apparently, someone made a computer virus by the name of Swine Flu and it has been infecting computers with email originating from @yahoo.co.jp. It has a subject title about “Swine Flu”. See excerpt of the report from Straits Times.
Japan’s National Institute of Infectious Diseases (NIID) said on its website that a suspicious Japanese-language email message with an attached file called ‘information on swine flu’ had been circulating in cyberspace.
‘The institute has received reports that the email message falsely identifying itself as coming from the NIID is circulating,’ it said.
‘The email is carrying a file titled ‘information on swine flu’, which has been recognised as an illegal programme by the institute’s virus-checking software,’ the NIID statement said.
What is the harm done, I am not sure. But when someone send you something about Swine Flu, be careful. Anyway, you can read about this Swine Flu virus on Symantec website.
