The last time you installed a large software, let us say a photo program, you just executed one command, for instance INSTALL or SETUP. After that the installation program took control, creating and deleting files. A few minutes later you have a lot of new code and data installed.
You had really no idea of what you had received. Hopefully all you received was good and may be it was. But think for a minute of all the millions of byte that were transferred and all the modifications that were made to the existing files. And all this was going on without your consent or knowledge.
A malicious code can do anything other program can. It can write a message on the computer screen, erase a stored file or stop a running program. Malicious codes can do different things every time. They can also do nothing most of the time and then suddenly act in a very dramatic way.
What is a malicious code? How is it possible that it can take control of a system? How can you recognize a malicious code? Is it possible to stop it? Let me try to give you some answers.
A malicious code is an undesired effect in a program or in a part of a program, caused by an agent intent on damage.

Then the virus destroys the other program or it exists with it. Also the good program can be modified. It then acts like a virus and starts to infect other programs. A transient virus acts when the attached program runs and terminates when the attached program stops. A resident virus locates itself in the memory of the computer and can remain active even if the attached program stops.

While you may not be held responsible for their antics, the aggravation and recurring pain you will go through in restoring your good name can be intense. Let’s take a look at some ways you can stop identity theft now.
Protect your social security number. There are very few people in life who really need to know your social security number. Besides government entities and certain creditors, no one should be asking you for that information. If they do, politely refuse or instruct them to mail their request to you in writing.
Block telemarketers. Make certain that your phone number is registered on “do not call” registries to keep telemarketers at bay. You control your phone; get caller i.d. to avoid those who slip through the loopholes in the law.
Chop it up. Important documents you no longer need should not be tossed in the trash without going through a shredder first. Purchase a unit that shreds your paper into small diamonds to ensure that no thief will piece back together important information and make you an easy victim of identity theft.
