A computer virus is a computer program that has the ability to infect a computer without the user’s permission, or even knowledge. There are more than a few similarities between computer viruses and human viruses.
Biological viruses enter the body through some kind of direct contact with the body and attach themselves to a host cell. The virus spreads, and the resulting damage can include pain, suffering, or even death. Similarly, computer viruses enter a host file in your computer when you open an infected email attachment. This virus then spreads, resulting in damage that can include deletion of files, a slowing down of the system. The hard drive of the computer may fatally damaged.
If these viruses are so damaging, why do people allow them to infiltrate their computers? Because people are tricked into it. Viruses are sent attached to email messages. These emails use a variety of tricks to fool the reader into opening up the attachment. For example, some of these emails are designed to appeal to people’s emotions. The “I LOVE YOU” virus included an attachment titled “Love-Letter-For-You.text.vbs.”Users, thinking they had been sent a love letter, opened the file, instantly releasing a virus and infecting their computer. Another common virus disguised as a personal message is “Koob.” “Koob” is spread through messages sent through social networking sites. The emails have subject line like, “you look so amazing and fanny on our new video.” When users try to download the “Video” , what they really get is a virus.
Do all you can to avoid exposing your computer to a virus. Think of the precautions you take against catching biological infections. You wash your hand and avoid contact with sick people. Extend the same care to your computer. Consider investing in anti-virus software. And whatever you do, avoid opening emails with potentially infected files. You may just save your computer from contracting a nasty illness, and yourself from suffering a terrible
