Incorrect Answers:
A: A computer virus is a program or piece of code that is loaded onto your computer without your
knowledge and runs against your wishes. Viruses can also replicate themselves. All computer viruses are
man-made. A simple virus that can make a copy of itself over and over again is relatively easy to produce.
Even such a simple virus is dangerous because it will quickly use all available memory and bring the
system to a halt. An even more dangerous type of virus is one capable of transmitting itself across
networks and bypassing security systems.
Some people distinguish between general viruses and worms. A worm is a special type of virus that can
replicate itself and use memory, but cannot attach itself to other programs. A virus is not what is
described in this question.
B: A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious
function when specified conditions are met. For example, a programmer may hide a piece of code that
starts deleting files should they ever be terminated from the company. A logic bomb is not what is
described in this question.
D: Adware is free software that is supported by advertisements. Common adware programs are toolbars
that sit on your desktop or work in conjunction with your Web browser. They include features like
advanced searching of the Web or your hard drive and better organization of your bookmarks and
shortcuts. Adware can also be more advanced programs such as games or utilities. They are free to use,
but require you to watch advertisements as long as the programs are open. Since the ads often allow you
to click to a Web site, adware typically requires an active Internet connection to run.Most adware is safe to use, but some can serve as spyware, gathering information about you from your
hard drive, the Web sites you visit, or your keystrokes. Spyware programs can then send the information
over the Internet to another computer. So be careful what adware you install on your computer. Make
sure it is from a reputable company and read the privacy agreement that comes with it. Adware is not
what is described in this question.http://en.wikipedia.org/wiki/Spyware
