So, insert a disk with an antivirus program into a computer optical drive. Wait for the disk auto.launch to work. After that, a window should appear with a program for installing programs.

How to install an antivirus program

The first computer virus was born almost simultaneously with the first computers at the dawn of the 70s of the last century. The first antivirus program was called “The Reper” and served the same goals that are also served by its heiresses. Only now she had to fight against a single and well-known virus, but what a modern antivirus can provide today’s computer to reliable protection from those dozens and hundreds of thousands of viruses, ready to collapse on your computer every second, and whether at least one of them can cope with such a difficult task.

The fact that no computer can be released today without a reliable anti-Octivirus watchman, everyone knows. But you can get infected without going to the Internet. Any local information medium. flash drive, disk, memory card. can become a carrier of the virus. programs introduced without the knowledge of the user into a computer capable of causing failures in work of various nature. And most importantly. The virus knows how to copy and multiply itself, methodically striking all the computer resources that he managed to penetrate. Antivirus program will help to resist infection. What kind of antivirus do you want to install on your computer, you decide. All of them more or less cope with their direct function. Here is a small list of leading companies engaged in antivirus development: DR. Web, Eset Nod, Symantec, Avira, Kaspersky Laboratory.

The virus that struck the computer can in every way prevent the installation of antivirus, in this case you will need Live-CD. Antivirus will turn on from such a disk at the time of the start of the computer and even before the launch of the system will find and neutralize all viruses. But such a maneuver can be needed only if you did not initially worry about security and allowed the infection of your computer system. In order to never face such a situation, develop an indisputable rule. the first program that you install on the computer before you start working with it will definitely be antivirus.

It doesn’t matter in favor of what antivirus program you will make your choice, they are installed all about the same. Run the antivirus installation file. Most of them will ask at the same time if you already want to turn on the protection mode in the process of installation. If you have an absolutely fresh system, the computer is not connected to the Internet, and you did not insert any extraneous information carriers into it, then you can safely click on “no”. But if you suspect that any virus could already penetrate the computer, then it is better to agree. Perhaps in the process of installation you will need to enter the serial antivirus number in a given field. You will find the number either on a disk box, or in the application to the installation file. Following the prompts of the program, you can easily and quickly install it. Do not be alarmed if immediately after starting the antivirus begins to issue alarming warnings. Most likely, he will inform you of outdated databases. For a successful struggle with new viruses, the antivirus will have to download information about new viruses from the server almost daily, otherwise it will not be able to resist them in any way. So let him calmly upgrade him.

Carefully read all the warnings that the program will give you. Perhaps she will need your help in recognizing some suspicious files or letters. Sometimes pop-ups or warnings can act on nerves, but you should not disconnect the computer protection because of this. The consequences of infection with the virus will cause you many times more troubles, and maybe they will generally lead to the destruction of the entire system. Therefore, install antivirus, it will not give you an absolute guarantee, but in 99.99% of cases it will protect from possible troubles.

Search for antivirus installed on a computer

Active user needs an antivirus, because independently it is not always possible to keep track of the processes that occur in the system. And they can be different, since even having downloaded only one malicious file by accident, you can seriously “infect” the computer. Malicious programs can have many goals, but first of all, they pursue the user system and fulfill their malicious code.

Information about the established antivirus can be useful in different cases. For example, when a person buys a computer or laptop, he can use the services of setting up and installing the system in other people. Arriving home, he may be wondering what his defense is installed. Situations are different, but there is a simple and effective way to find out the established antivirus.

We are looking for the established protection

One of the most effective ways that does not imply an endless search among the installed software of the same program is viewing through the “control panel”. Windows has the opportunity to find out the protection installed on the computer, therefore, use it more efficiently. The exclusion is incorrectly installed applications, since they may not be displayed in the list.

This example is shown on the Windows 10 system, so some steps may not match the OS of other versions.

You can make it easier by looking at the list of programs in the tray. When you point the mouse cursor to the icons, you will be shown the name of the advanced program.

This search is not suitable for little.known antiviruses or for users who do not know the main antivirus programs. And besides, the protection may not glow in the tria, so the method of viewing through the “control panel” is the most reliable.

Well, if there was no antivirus, then you can download anyone to your taste.

Operating systems most susceptible to malicious
