It's important to understand the reasons why protecting your computer from viruses is so important. Being a victim of a virus is not the only threat. Viruses can use your computer as a way to infect other computers and spread the damage that they can cause all over the world. It's very important to have your computer protected by anti-virus software before you ever even go on the Internet. If you don't, your computer will get a virus within 2 hours of being online and then possibly send it on to all the contacts in your address book.

There is an economic argument towards being protected as well. If you buy an antivirus program from a reputable company, it might cost you $50. However this would be small money in comparison to the cost of your computer becoming infected. Home users and small businesses should think of the cost that your computer systems cost you initially. You must also factor in your monthly outgoings like Internet connection etc. A virus could destroy your whole system and cost you a lot to set up your computer again.

Now think of all the personal details you have stored on your computer, financial records, pictures and other private data. That anti-virus program is a small price to pay in comparison. If you don't protect your computer, you are leaving a door open for any virus or Trojan that may wish to enter your computer. These malicious programs are designed to find computers that are not protected against them.

Once a virus takes your information, it might not just corrupt and delete it. Much more malicious things can be done with your information, such as identity theft. One of the main benefits of antivirus software is that it's regularly updated. Anti-virus companies keep track of the new threats that are created daily. Malicious programmers are continuously evolving their code. Anti-virus software takes the stress off the computer user; your safety is being dealt with automatically. Also, It's important to note that if your computer is used as a way for a hacker to attack other computers that you may be held legally responsible.

If you are still unsure about buying anti-virus software it's important to note the famous Melissa worm. The worm was created by a David L. Smith. Once caught, he was fined $5,000 and was imprisoned for 20 months in New Jersey. However the worm that he had created has an estimated value of damage amounting to more than 55 million dollars.
