How to Work Computers Virus

Computer Viruses: A computer code that can "breed by itself" which put some or all of the code in the file or application, and cause your computer to do things you do not want.

Computer viruses is a common disease in the world of modern technology. They can spread rapidly through open computer networks like the Internet, and resulted in losses up to billions of dollars in a short time. Five years ago, chances for infected by a virus within a period of 12 months is equal in 1000; now the ratio has risen dramatically to a proportional 10. Vital statistics of the virus:

• viruses into your system via e-mail, downloads, infected floppy disk, or (sometimes) by hacking.
• From the definition, a virus must be able to perform "self breeding" (aka make a clone or a copy of itself) to be spread.
• We have thousands of types of viruses, but few are found "in the wilderness" (wander, undetected, within the network) because most of the known viruses is born from a lab, which is a variant of the virus "wild" which is widely available in world.
• Effect of virus generated varies, ranging from annoying to very destructive, but even the simplest virus has a tendency to damage because of the bug on their computer code (because the virus programmers do have a very careless or malicious intent).
• antivirus software on the market today can detect almost all types of viruses exist, but should be updated regularly to maintain effectiveness.

A virus is simply a computer program. Like other computer programs, in which there is instruction that can tell the computer to perform certain tasks. But with different application programs, a computer virus is usually ordered you to do the things that really do not want, and usually can spread itself to existing files on your computer - and sometimes into other people's computers as well.

If you're lucky, a virus is at best only cause the computer to act weird, such as causing your computer speakers reads "blip-blip-blip" at random. The most feared is the malignant virus that can cause all data on your hard drive is missing (with a computer command to format the hard drive), even some viruses that can damage your computer hardware, such as the CIH virus damage to your computer motherboard BIOS.
