Detailed Analysis

According to this message, Internet users should watch out for an email that contains little red shoes dancing to a cheerful song. Supposedly, the email offers the recipient one thousand free songs via a link in the email or an attached file. The message claims that downloading the file will launch the Kleneus66 virus, which will wipe all files from the infected computer and completely destroy its hard drive.

However, the claims in the message are untrue. There is not, nor has there ever been, a virus like the one described in this email. In fact, the message is a hoax that has been circulating in various forms since 2003. The hoax originally circulated in Portuguese but was apparently later translated to English. Earlier versions of the hoax referred to the supposed virus as "Kleneu66" rather than "Kleneus66".

While some viruses may be able to delete or damage files, there is no virus, worm or malware that can physically destroy the hard drive on an infected computer. Such false claims have been featured in a number of similar virus hoaxes, including the Virtual Card For You Virus Hoax and several of its later variants.

Internet users should certainly be cautious of opening attachments or following links in unsolicited emails that promise free music, videos or information. Such ruses are commonly used to distribute worms and malware. However, forwarding false warning such as this will help nobody. Before sending on a virus warning it is important to check that the warning is accurate and describes a real and current threat.

If you receive this hoax virus warning, please do not send it on to others. And please help to stop its further distribution by informing the sender that the message is a hoax.
