Self-copying computer pest - what is it and what is its mechanism of action? How are they created and who creates them? What species exist and what does a particular species do? Now you will learn what a self-copying computer pest is. The answer is divided into 6 parts. Considered not only the classification, but also ways to get rid of and safety precautions, so that you never learn about them in practice.
Self-replicating computer pest - what is it?
Initially, you need to decide on the terminology. A self-replicating computer pest is the full name of a computer virus. These are programs that independently increase their numbers, reducing the amount of memory space available to the user and at the same time conducting sabotage activities. Sabotage can be either relatively harmless (taking part of the RAM for copying) or have significant consequences (up to the computer crashing).
One of their features is that they can not only spontaneously copy themselves, but also embed their code into othersprograms. True, in view of the fact that a fairly large piece of code is required for the full functioning of viruses, the target programs must also be rather big. They got their name "viruses" due to their similarity with biological viruses. Additionally, over the past few years, models have gained the ability to carry out self-adaptation, which further increases the similarity. Self-copying computer pest is the answer to many computer problems and will continue to occur until the virus is removed.
The history of viruses
The first Brain virus to carry out a massive attack was developed in 1986. And already in 1987-1988 there were peaks of his popularity. There were viruses before him, including in the Soviet Union, but their actions did not acquire such a scale. Since then, the number of viruses has steadily increased, and today there are over 7 million of them.
What types of viruses are there?
Many viruses have been developed by different people and are classified based on their actions. There are 3 types:
- Worm. Pretty harmless program that just deals with self-copying and using RAM. But with a significant infection, it can create significant inconvenience when using a computer. This is especially true for those that do not have enough RAM,so that the worm develops for a long time.
- Zombie virus. These viruses are used for remote access by a computer. The usage aspect includes a wide range of actions, from participating in a spam attack on a site to being infected with a mailing list program that will send emails on the Internet. Moreover, everything is done so masterfully that the user does not even notice that his computer is in the clutches of intruders.
- A program that blocks access. It is a banner that blocks the window and requires you to send money somewhere. As you might guess - after sending the money does not disappear. You can uninstall such a program in safe computer mode.
- Programs that harm your computer. Software that destroys system files, disabling he althy machines and turning them into piles of iron and plastic.
Is there a difference between a virus and malware?
Very often, the words "virus" and "malicious program" are put with an equal sign. Is it really so? No. The fact is that in addition to viruses, trojans and spyware fall under the concept of malware. And the very concept of "malicious programs" is broader - so, they are all software that is used to gain unauthorized access to a computer with criminal intent. In addition, a self-copying computer pest is software that can be embedded in other programs, while Trojans and spyware are deprived of such an opportunity.
How to removevirus?
The easiest and most popular way is to resort to the help of an antivirus (and an antispyware to guarantee the destruction of the spy). But there are separate programs that register themselves in the registers of the operating system, and only professionals can handle them. If you decide that you should take your computer in for repair, then this is premature: on large computer forums there are help departments for computer problems, contact them for help and you will be advised on how to find a virus and how to remove it.
How not to catch a computer virus?
The best problem is the one that doesn't arise. And for this you need to be careful:
- Download files only from resources after which you don't notice something "new" on your computer.
- If the downloaded file has an.exe extension but an archive icon, don't open it (it may be a self-extracting archive, but they are hardly used, and most likely you have a virus in front of you).
- Estimate the approximate size of the file you need and downloaded. So, if you need a program for a couple of kilobytes or a couple of gigabytes, and you are offered a file for 500 kilobytes, this is a virus or other malicious program.
Now that you know that there is such a program as a self-copying computer pest, what it promises with a frivolous attitude, you can be more careful and careful. This reduces your chances of meeting them and learning for yourself.experience what they are.
