No matter what operating system you are actually using your personal computer, you need to determine whether or not your computer is open to outside attacks from hackers and crackers.
Sometimes this vulnerability to your computer doesn't even exist within the operating system rather than network that the computer is connected to. This can mean that both the Macintosh and Windows operating system computers are susceptible to outside attacks.
Outside retailers will sometimes offer you the ability to purchase antivirus and anti-spyware computer software in an effort to help you protect your system.
While this software is sometimes effective often it is the case it is over sized and unusable to the normal computer user.
