How the Virus Computer Work

Viruses generally have a relatively common way of working that is:
1. The ability to obtain an information
2. The ability to check a file
3. The ability to replicate and transmit themselves
4. The ability to manipulate the
5. The ability to hide itself.
Virus in getting an update from the list of files in a directory. The virus then look for files that can be infected, when users open a program or file that is infected by a virus, the data needed by the virus created. Viruses usually perform data collection and store it in RAM, so if the computer is turned off the data will be lost. And the data will be created again when the computer is turned on, the data are usually stored as hidden files by viruses.
Virus infection before it checks the file to be host. It is not much different from the behavior of the virus in the human body.
In general, the virus would give a sign to the file or program that has infected so easily recognized by the virus. Like giving a byte or a unique creation date for each file that has been infected.
The multiplication process itself is done by the virus after giving a sign to the file followed by writing the object code of the virus on the files that have been checked. Multiplication process is generally done by removing or changing the host file and then creates a file that contains a virus program to use your real name or by riding on infected files. Manipulate a file that is infected can harm computer that can eventually damage a computer. As an example in 1998 CIH virus that causes damage that can only be solved by replacing / repairing hardware components. Manipulate activity in general has a goal to popularize the name sipembuat virus. Capabilities that are owned by a virus is the ability to hide itself. In this way the virus is stored in coded form and machines combined with other programs, put the program on a Boot Record or track on a disc. The program is made as short as possible so that infected files do not change size significantly.
Like most viruses in medicine, computer virus also has a life cycle is generally divided into 4 stages:
1. resting phase virus generally specify a date or time to
activate the virus on computer
2. deployment phase, generally virus to replicate itself with
reproduce itself on a course to a place in the media
storage (hard disk, RAM, Disk, etc..)
3. active phase, this phase will enable the virus itself
4. execution phase, this phase has been active virus began operating.
