History and Background

The virus was one of the first ever threats to computer security. It brought a whole new fear upon computer users. Bugs and glitches could cause damage unintentionally, but a virus created havoc intentionally, and therefore often caused much more damage then just glitches in software. Technically a virus must be in a host file and spread manually by people, versus a worm which spreads by an automated process and doesn't require a host file, but we will include worms as part of the term virus. Therefore, the threat of viruses quickly multiplied expotentially. One computer infected by a virus is manageable, but a virus spreading uncontrollably and automatically can cause damage to sometimes entire populations. And with the introduction of the Internet, billions of computers worldwide could be accessed with a click of a button. These abilities are what made the virus probably the greatest security to personal computers in the 21st Century.

What kind of damage will it inflict?

Since up to 100 new viruses are discovered every minute by anti-virus industries worldwide, the damage they inflict varies considerably. Some will display an annoying popup. Some will swap your mouse buttons. Some will uninstall Internet Explorer. Some will delete all your personal files. And some, though rare, will slow down your computer fan to the point that your computer processor starts smoking. All have 1 thing in common - they reduce your productivity in some way and they inhibit you from comfortably using your PC. Therefore you must take several precautions to insure you do not to become infected with viruses. With just a few simple security measures, the chances of getting infected with a virus can be cut down by over 90%.
