Dealing with Viruses and Other Security Problems

Computers provide connectivity with others, which is great, but this also brings with it some security issues that need to be handled. If you are connected to the Internet, if more than one person uses your computer, or if you share work (perhaps by bringing work home from the office or collaborating on a project and sharing files), you need to protect yourself.

Security has become a big issue, and you should take these risks seriously. While a computer is replaceable, you may find that the data you stored on it is not. For instance, suppose that you just finished writing the next great American novel, and you have only your disk files from the hard drive. If something happens to those files, poof, your entire novel and all your writing may be lost. Or, suppose that you store all of your financial records on your laptop, and the laptop is stolen.
