If you don’t have the latest security updates, you could be in danger of being attacked by a worm that spreads through low security networks, PCs and even memory sticks. The malicious piece of software has been infecting under several different names including Conficker, Downadup, and Kido.

First discovered in October 2008, this worm is posing an increasing threat on Windows’ users. To combat this, Microsoft have released a patch, however the worm has already infected over 3 million machines.

According to experts, this figure could potentially be far higher. It is advised that users should have up-to-date anti-virus software and install Microsoft’s MS08-067 patch to protect themselves against this dangerous worm.
