Since some people remembered about it only after the harm received from the activity of malware or viruses. But just thinking about it is not enough. You need to be able to make the right choice among the many proposed options, and then also figure out how to install the antivirus on your computer.
general information
The speed of development of modern digital technologies has a significant impact on human life. More and more computers come into our lives, which make it much easier for us to perform various tasks. Now it’s impossible to imagine how they used to do without all this. A lot of different information is stored in a PC, and every day it becomes more and more, and part of it is confidential. In this regard, there is a task to preserve it in integrity and safety.
Especially now, when computers are used to carry out banking operations, and pay for goods / services, and transfer important documents. The further you go, the harder it becomes. The number of people who want to use user devices and the global network for their own selfish purposes is growing. Security is especially important for active travelers on the Internet. Protected by specialized software, part of which are antiviruses, both paid and free. This is the issue we are going to do now.
Install a free antivirus
After making sure that viruses, trojans, rootkits and similar malware do not disappear anywhere, we proceed to the choice of protection. In principle, it is well known that there are a lot of antiviruses and they all differ from each other in their purpose and capabilities. Some of them, in addition to the paid version, can offer a full free. Which of them are the most famous? These are Kaspersky, Nod 32, Avast, AVG, Panda, Dr. Web, Avira and some others. But, according to testing by AV Comparatives, only Avast has a decent free version for use on a home computer.
If you decide to install a free antivirus on your computer and it will be Avast, you can stop worrying about its security. This program is built on the principle of modules, each of which works in real time completely autonomously and provides continuous protection against its specific type of threats. For example, there are such screen modules as the file system, web space, mail, Internet chats, P2P clients, heuristic screens for behavior and scripts. This amount is the most optimal and is calculated on the basis of possible threats.
How Avast antivirus is installed and works
If you chose this program, then with Avast you will not have a question how to install an antivirus on a computer. Download from the official site, run the executable file, and then your device together with the installation program will do it all yourself.

Install “Basic Protection” and closely monitor the process, as a paid version will be constantly offered. This antivirus monitors in real time all running programs and provides protection against rootkits and spyware.
You will also be warned about visiting dangerous sites and decide for yourself whether to visit them or not. Malicious scripts will be blocked in this case. If in doubt about any application, run it, for starters, in a sandbox, a completely isolated environment. You do not need to worry about such an important business as updating the virus databases. The program itself, using the Internet connection, will do all this. Therefore, if you want to install a free antivirus on your computer and sleep “calmly”, pay attention to “Avast”. It has only two drawbacks: the obsession of individual functions; sometimes makes inadequate decisions.
Another serious protection is Doctor Web antivirus.
An equally popular program used by many users is Doctor Web. Antivirus on a computer from this manufacturer is characterized by the fact that to evaluate its performance, a 30-day free full version of the product is offered. Having experienced it during this time, you will be faced with a choice - to remove or acquire a commercial license. Let's talk a little about this application. Recently, its interface has been significantly updated. And not only this.
