The first computer virus was born almost simultaneously with the first computers at the dawn of the 70s of the last century. The first anti-virus program was called "The Reeper" and served the same purposes as its current heirs. Only now she had to fight against a single and well-known virus, but what modern antivirus can provide today's computer with reliable protection against those tens and hundreds of thousands of viruses that are ready to fall on your computer every second, and in general, will at least one of them cope with such a difficult task.
Instructions
Step 1
Everyone knows that no computer can be released online today without a reliable anti-virus watchdog. But you can get infected without going online. Any local storage medium - a USB flash drive, disk, memory card - can become a carrier of a virus - a program that is introduced into a computer without the user's knowledge and can cause malfunctions of various kinds. And most importantly, the virus is able to copy and multiply itself, methodically affecting all computer resources to which it managed to penetrate. Antivirus software will help to resist infection. What kind of antivirus you want to install on your computer is up to you. All of them more or less cope with their immediate function. Here is a small list of the leading antivirus companies: Dr. Web, Eset NOD, Symantec, Avira, Kaspersky Lab.
Step 2
A virus that has infected a computer can in every possible way prevent the installation of an antivirus, in which case you will need a Live-CD. From such a disk, the antivirus will turn on at the moment of starting the computer and, even before the system starts, it will find and neutralize all viruses. But such a maneuver may be necessary only if you were not initially concerned about security and allowed your computer system to become infected. To never face such a situation, develop an immutable rule for yourself - the first program that you install on your computer before you start working with it will definitely be antivirus.
Step 3
It doesn't matter which antivirus program you choose, they are all installed in about the same way. Run the antivirus installation file. Most of them will ask if you want to enable protection mode during the installation process. If you have a completely fresh system, your 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 a virus may have already entered your computer, then it is better to agree. Perhaps, during the installation process, you will need to enter the serial number of the antivirus in the specified field. You will find the number either on the box from under the disk, or in the attachment 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 starts to issue alarming warnings. Most likely, it will inform you about outdated databases. To successfully combat new viruses, the antivirus will have to download information about new viruses from the server almost every day, otherwise it will not be able to resist them in any way. So let it refresh calmly.
Step 4
Carefully read all the warnings that the program will give you. She may need your help in recognizing some suspicious files or letters. Sometimes pop-up tips or warnings can get on your nerves, but you shouldn't turn off computer protection because of this. The consequences of a virus infection will cause you much more trouble, and maybe even lead to the destruction of the entire system. Therefore, install an antivirus, it will not give you an absolute guarantee, but in 99, 99% of cases it will save you from possible troubles.
