Downadup virus exposes millions of PCs to hijack

This looks very nasty virus that is going around the internet. It has spread to more than eight million computers. The Downadup or Conficker worm exploits a bug in Microsoft Windows to infect mainly corporate networks, where it potentially exposes infected PCs to a hijack.

A computer that is connected to your corporate network will immediately scan the network looking for machines to infect. These will be machines that have not installed a patch from Microsoft known as MS08-067. The worm will also scan company networks trying to guess your password, trying hundreds and hundreds of common words. If it gets in, even if you are not at your machine, it will infect and begin spreading to other servers. A third method of spreading is via USB data sticks.

To prevent this from happening you need to download the patch called MS08-067 from Microsoft. You can use uncommon long passwords. If you have a way to send out patches through SMS or WSUS then you should be doing this.
