In this modern Information Age, computers are necessities in life. Whether we use them for simple functions such as typing our homework and business reports, up to more important acts like online business meetings and transactions, one cannot deny that computers are a big part in our daily lives. Using a computer, particularly the Internet, is one task that even a ten year old can do at this particular period in time. With the growing increase of popularity and reliance on computers, as well as the demand for it, security risks have also gone up, which is a reality that cannot be ignored. With the billions of information bits being spread across the World Wide Web, hackers and computer intruders (criminals) see the value in focusing their attention to computers and the Internet. The information they would retrieve here is (more often than not) more useful than when doing it the old-fashioned way. As such, these intruders have devised methods to get information out of computer users, with or without these people knowing that they�ve been hacked. As is the case in real life, there are some computer programs that are disguised to be innocent, but actually act as spies, providing information to the intruders. These malicious programs, which are security threats, are called computer viruses. Computer viruses should not be taken lightly. They work in many different ways; one of them may be to provide data to the one who planted the virus.
