Computer that we buy usually is just a Starter Kit.
It includes a set of CPU unit, monitor keyboard, mouse, and a set of speaker (optional).

For some people that is probably just doesn’t matter. But, for other people that is not enough specially with the latest technology update. They need more than standard package.

Recently, computer with a full multimedia capabilities, good graphic tools, and able to accommodate various portable are needed by users.
The only way to get those extras is by accessorizing, because the extras are not included in a standard package computer.

I’m going to use a pizza as an analogy.
A brand new computer is a plain pizza, we need to flavor and bake it to turn it into something useful
To make this plain pizza turn into a delicious pizza, we need to “accessorize” this pizza with an onion, cheese, chicken, beef, and everything else depends on your favorite.

Just like a plain pizza, this new package of computer is standard (plain). It requires to be accessorized.
Accessorizing a standard computer doesn’t have to be so expensive, but it depends on what you need to use the computer for. If you need the computer for children, you can spend less expensive for an extra software and hardware.

If you use the new computer that you buy for working purpose, that requires a high quality result, than it would be more expensive.
And if you need more peripherals such as microphones, video cameras, digital cameras, scanners, PDA’s and more, that is going to be a lot more expensive.

Accessorizing computer sometimes can become another important thing to consider besides cost. The best time to buy is when you buy a brand new package of computer.

You probably wonder why can that be another important thing to consider.
Because technologies are growing rapidly, manufacturers develop new technology continuously. If you decide to buy accessories later, by that time a newer technology have been released and probably you computer can’t accommodate the new peripherals.

That kind of problems are usually experienced by users who are attempting to use hardware that were designed for Windows Vista on Windows XP or Windows 2000 machine.

Virus is a computer program that able to spread from one computer to another computer.
They are designed specifically to gain access into parts of your computer system and they have the ability to duplicate and infecting another computer.

Below is some of the most common methods for a computer virus to spread.

Boot Information

Every disk (hard disk, floppy disk, CD, DVD) contains a boot sector even if it is a bootable disk or not.
When you turn on your computer, then it will search for boot information.
If the computer finds a disk containing boot information, it reads the boot information and uses it to start the computer in normal procedure.
For an example if you accidentally boot your computer from a bootable CD that contains a computer virus, that way the computer virus are being triggered and it is possible to be transferred into the computer’s hard drive.

After the boot information on the hard drive has been infected with the virus, it will be loaded into your computer’s memory every time you start your computer. From that memory (RAM) the computer virus infecting every disk that attached with your computer. This is how the infection spreads.

Most boot viruses could stay on a computer system for a long time without generating problems, it was designed only to stay there and spread themselves.
Such computer viruses are designed to activate their bad behaviour on a specific date depends on the creator.
But there are some nasty boot viruses that can destroy the boot information or forcing a complete format of a hard drive right after they are transferred into a computer.

Application Infections

When a computer program that has been infected with a virus is running, the virus is loaded into the RAM.
While the virus is in the RAM, if you are running another application that application can become infected.
It means that more applications on your system are possible to be infected.
Multiple infections are very common and it will definitely generate system problems.

For some time the program files may operates normally without any problems but eventually they will have problems or the infections causes the whole computer system down.

Generally, when an application is infected with a virus, the first sign of an infection is when you are saving files it is saved without a proper names or the data that you save is incomplete.
This type of viruses are often designed to search for a programs that are used to share information between users/computers such as email applications, screen savers, office document Macros, and self-extracting compressed files.

E-Mail Attachments

Most of dangerous viruses are spreading through an e-mail attachments.
In such cases, the user does not realize that they are attaching infected file/s to an email message and send it to a friend/s or colleague/s.
By the time that email is received, the virus is triggered when the attachment file is opened then infecting a new computer.

These days mass mailing email contains worms or viruses are being released.
These kind of attacks AUTOMATICALLY scans your computer’s files and search for any email address it can find and uses your email application to AUTOMATICALLY send infected messages to every email address that it has found in your computer.

It is very important to be aware over the emails that you open. Make sure that it does not contain dangerous viruses.
Even if that email comes from your family or friends, it may contain a virus.
This is the moment where an anti-virus program would be really helpful to detect your incoming messages and to make sure that the messages you receive does not contain a virus.
