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 hoaxthat 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.

Importance Notice

After considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.

These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.

Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.

And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.

When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.

I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.

A Big Thank You

I would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.

I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.

Closing Date

Hoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.

Thank you, one and all!
