With the advance in technology, more affordable prices on computer equipment, and the availability that the internet provides to common daily tasks such as bank on line, purchasing items on the internet, email or chating with your friends online, checking for a book or a show time on a movie in your neighborhood theater, more people are buying more than one computer for their personal use. This common usage of the Internet has opened doors for cyber crimes. Computers are the targets from different types of crimes, including:

• Viruses that infect files deleting their contents or wiping out the whole hard drive
• Remote attack that steal user’s identity or user’s information
• Spywares that monitor users browsing activity to collect information on the user and redirect their web browsing activity or interfere with the user control on the computer
