Remember the Panda joss-stick virus case? Now that those guys have been arrested, another new virus has appeared and experts say this one is much more vicious. The Hao virus attaches itself to all the .exe files on your computer, making them appear with the Chinese character 浩. If you've already been attacked by this virus, good luck. Not even professional data recovery guys are likely to be able to help you recover your files. So, boys and girls, be good and remember to update your anti-virus programmes and back up your files.
