Have a look at this map developed by a Security company called Norse (http://norse-corp.com/about.html). They created this live map showing less than 1% of the attacks on their systems at anytime. Anyone whose been in my classes now how I feel about viruses etc. This shows just how much they are out there. Rememeber this is less than 1% of one company
Click the blue box headers to make them smaller and see the map, or click on the black/map area to get taken to the original site and see it properly.
Enjoy the summer, and update your antivirus :)
