Recently, massive virus attacks on computers have become more frequent, which is why even the most skeptical users think about installing anti-virus protection. In our article today, we want to talk about how to install an antivirus on a computer for free.
The procedure consists of two stages: choosing the right product and downloading it, as well as directly installing it on the computer. Consider also possible problems and methods for their elimination.
Stage 1: Choosing an antivirus
There are dozens of solutions on the market from many companies - both from large players and from newcomers to the industry. Our site contains reviews of the most common security packages, including both paid and free software.
If protection needs to be installed on a low-power PC or laptop, we have prepared an overview of solutions that are not resource-demanding, which we also recommend reading.
We also have a detailed comparison of some free protection options like Avast Free Antivirus, Avira and Kaspersky Free Antivirus, so if you are choosing between these programs, our articles will come in handy.
Stage 2: Installation
Before starting the procedure, make sure that there are no other antiviruses on the computer: such programs very often conflict with each other, and this leads to various kinds of failures.
If a security application is already installed on your PC or laptop, use the instructions below to uninstall it.
Installing antivirus software is not much different from installing any other program. The main difference is that you cannot choose the location of resources, since such applications must be located on the system drive in order to be fully functional. The second caveat is that the installers of most antiviruses are not standalone, and download the necessary data in the process, so they need a stable Internet connection. We will show an example procedure based on Avira Free Antivirus.
- When downloading from the official site, available as a separate Avira Free Antivirus, and Free Security Suite. For users who only need general protection, the first option is fine, while those who want additional features like VPN or secure web browsing should choose the second one.
- Run the installer when the download is complete. Before starting the installation, be sure to read the license agreement and privacy policy available at the links marked in the screenshot.
To start the procedure, click on the button "Accept and Install". - Wait while the installer prepares the necessary files.
During the installation process, Avira Free Antivirus will offer to add some additional components to it. If you don't need them, click "Skip Review" top right. - Click "Start Avira Free Antivirus" upon completion of the procedure.
- Done - security software installed.
OS Windows 7 are a favorite target for viruses. The use of antivirus software is essential to protect against viruses, spyware, and other malicious code.
Exists many antiviruses available for download. AVG Antivirus is the most popular antivirus software, it works perfectly with Windows 7 and provides complete antivirus protection for your computer. Another popular antivirus package, Avast, is able to protect against all types of viruses, is easy to install and use, as it has a nice interface. Scanning occurs many times less, which is rare for free antiviruses.
Kaspersky Anti-Virus combines the best virus and spyware detection rates with new technologies to ensure effective protection against malware. It can be easily downloaded, installed and configured. Kaspersky Anti-Virus offers a wide range of universal settings for fine-tuning the program.
How to choose an antivirus?
It is best to use well-known antiviruses, among them there are also free versions, they are not so effective, but antivirus databases will always be on top.
First of all, you need to decide how well you need to protect information on your computer. The best antiviruses and firewalls that can protect your computer from hacker attacks, most require you to pay a monthly fee, and free antiviruses generally provide only superficial protection against well-known viruses. Whether you are ready to pay extra for the safety of savings in toys, or vice versa, you are ready to risk the safety of the company's accounting records using a free antivirus - it's up to you. If the information is not of particular value, it is worth installing the simplest free antivirus.
With the value of information - everything is simple. Think about how important the information is on your PC, and how important it is to keep it secret, how useful it will be to your competitors, if any. If only the safety of information is important, then you can simply make backups (backup copies, for example, to flash memory), and save on antivirus fees using free versions.
If you keep information on your computer (business plans, any important reports) - you should not save on antivirus. It doesn't matter which risk group you belong to or which sites you visit. There is an opinion that there are a lot of viruses on sites with "doubtful content", but this is not true. Attackers try to disguise viruses, disguise them as quite decent content, and most often a virus can be picked up on social networks, on thematic forums dedicated to profitable businesses, and even on official websites of tax services, the protection of which does not always cope with attacks by intruders.

A new version of a Kaspersky Lab product called Kaspersky Free has joined the ranks of free antiviruses with real-time protection.

So we got our hands on the free Comodo Internet Security. This is a set of tools to protect your computer, which includes a firewall, antivirus and a proactive protection module. I will not describe all the features of Comodo Internet Security, because, in my opinion, they are standard and are present in most similar programs. The main difference between this program and the rest is its free and amazing reliability. When properly configured, the program allows you to secure your computer to the maximum. The other day I reviewed several comparative tests that various companies conducted, and the results of these tests quite surprised me. As an example, I will give the results of one of these tests.

Today I will talk about another free antivirus Avira Free Antivirus, which recently settled on one of my computers. The situation with it is special, since this antivirus is not a simple scanner, it does not need to be downloaded every time you need to check the system. This antivirus hangs in memory and does everything on its own. It downloads and installs updates on its own, independently checks the files accessed by the operating system and various applications.
A massive attack by the WannaCry ransomware (WannaCryptor, WanaDecryptor) has infected tens of thousands of computers in organizations and public institutions around the world. The malware exploits a known vulnerability described in security bulletin MS17-010 and a combination of EternalBlue / DoublePulsar exploits that can attack other vulnerable Windows systems on the same network. As a result, infection of one computer can lead to compromise of the entire corporate network in the organization.
After being introduced to a computer due to the successful exploitation of a vulnerability, the WannaCry ransomware encrypts all files and documents of certain formats by executing remote commands sent via the SMB protocol and spreading to other Windows computers on the network.
Perhaps you are too trusting, and therefore did not install an antivirus on your PC, or the license for your antivirus has already expired, or the antivirus you have installed does not provide maximum protection, and ... maybe your PC is infected!

For the vast majority of home users of Windows 7 and Windows 10, Microsoft's regular antivirus product is fine. In the Windows 10 operating system, it is already built into the system called Windows Defender and does not need to be additionally downloaded and installed. But for Windows 7 you will have to install by downloading the Microsoft Security Essentials distribution from the Microsoft website. In fact, this is the same product, but with different names for different systems.

Dr.Web CureIt! - an antivirus that is noticeably different from the usual programs for everyone. This utility does not work all the time, preventing malware from appearing on the computer. It allows you to cure an already infected PC from viruses, Trojan horses, rootkits, etc. This feature of Dr.Web CureIt! defines the scope of the product. It can be used periodically to check the reliability of the antivirus installed on the computer, as well as in cases where, based on indirect signs, infection of the PC can be suspected. In general, Dr.Web CureIt! hard to overestimate.

Continuing the popular theme of free antivirus, I want to mention another development that I met relatively recently and which I have not had time to write about yet. In theory, it would be possible to add this information to the original message, but I decided to put everything in the form of a separate note. So, today we will talk about a free antivirus from Kaspersky Lab called Kaspersky Virus Removal Tool.

An interesting free antivirus program is released by Microsoft Corporation. The utility is called Malicious Software Removal Tool (Malicious Software Removal Tool for Microsoft® Windows® OS). This tool automatically scans your computer for a range of malware and removes them immediately when it is found. The tool is not a replacement for a regular anti-virus utility, it only allows you to conduct an express analysis for common viruses.
