We live in a digital world today. We use our computers to store photos of our kids, school papers, bank transactions and thousands of other critical pieces of data. All this data is stored on a hard drive inside the computer. Hard drives don't live forever.

Santa Clause brought the kids a wireless network this year. You opened all the boxes, plugged everything in and ran the setup software. Every computer in the house shares your high speed Internet connection now. Works like a charm....right? Not so fast.

It seems like everyone with a computer has high speed internet access. Both cable and DSL offer speeds that make dialup connections obsolete.

There is a security problem with these connections though. As fast and easy is it is to get to the internet now, it is just as fast and easy for other computers on the internet to get to you! That's why computer worms like Blaster have been able to spread so easily.
