Owning a computer is a relatively large responsibility, especially when one observes the amount of maintenance and cleaning involved in keeping your computer in as best a condition as possible. Through excessive use a computer can become quite crowded with useless information, which takes up space on your hard drive and consequently slows down the speed at which your computer operates. Much of this information comes in the form of what is called "cookies" and is obtained via accessing the Internet. These cookies are generally harmless other than the slowing effect they have and can easily be wiped from your hard drive. However, sometimes access to the Internet may result in your computer acquiring a virus.

Basically a virus is a piece of software that seeps into your computers system and attaches itself to files on your hard drive. Every time that these virus-ridden files are executed, the virus has a chance to reproduce or duplicate. The magnitude of the damage a virus can cause through a single period of magnification is enormous and can have detrimental effects on your computer. In some instances the virus can go so far as to render your computer completely useless. Viruses can travel from user to user incredibly fast as well. Some have been know to infect millions of computers in a number of days.

If your computer somehow contracts a virus, the process of removing it may be quite rigorous and likely result in the loss of the information on your hard drive. You may be lucky enough for the virus to not have progressed far into the inner workings of your system though and in such a case it may be removed without extreme difficulty. To lessen your computer's chances to obtaining a virus you should invest in protective software as this can help you defend against infection without as much concern.
