3 ways to install antivirus

Malware and viruses are programs designed to damage your computer or steal your personal information. Antivirus programs are programs designed to fight viruses and malware in order to eradicate them from your machine. If you use Windows and if you connect to the Internet, it is essential to have a good antivirus. You may also find it useful to install one if you are working with a Mac or Linux although these systems are less affected by viruses.


Method 1 of 3: In Windows

Install an Antivirus Step 1

Step 1. Understand the importance of an antivirus

Of the three major operating systems, Windows is the most vulnerable to viruses and malware because it is the least protected system and the one with the most users. An antivirus program defends your computer against viruses and malware that can install themselves on your machine from websites, USB drives, emails and downloads.

Step 2. Purchase an antivirus

Some popular free antiviruses are particularly good at protecting your computer against viruses and malware. They offer constant updates to protect you against the latest viruses and malware. Avira is free and very good, there are others that are free and effective.

  • If you visit risky websites or frequently download files that are susceptible to infection, it is best to install a paid antivirus. These programs are more powerful and they will protect you more effectively. Some can be purchased and others are available for an initial subscription and an annual fee.
  • When you download an antivirus, do it from the official website of the program and choose a recognized program, whether free or paid. Some programs that are supposed to be anti-virus software install malware on your computer themselves. Visit websites and magazines with serious information about the most reputable antiviruses to download software that has been on the market for some time.
  • On Windows 8 and 10, there is Windows Defender, a free antimalware provided by Microsoft.

Step 3. Install your antivirus

You must be connected to the internet to download and install the program and recent updates. Before installing your antivirus on your computer, close all programs that are running.

Some free antiviruses that you download offer the option of installing a toolbar in your search engine. This can sometimes give you better protection, but it can also alter your preferences and if you have a somewhat old machine it can cause you problems. During the installation of the antivirus, you have the possibility to accept or not. Carefully read the messages appearing in the installation window before clicking "continue" or "install"

Step 4. Update the antivirus

After installing your antivirus, you need to install the latest updates. The antivirus usually does not contain the latest updates. If it does not do this automatically, the program usually suggests that you install recent updates, accept or click on the "update" option to connect to the program's server. Most antiviruses have an icon in the taskbar (bottom right of the screen) that you can right-click to open a small menu offering you different possible actions, including the update.

Antivirus programs usually have the “automatic update” option pre-selected. Check if this is the case by going to the "options" menu of your antivirus. If you do not want to enable automatic updating, update manually at least once a week

Step 5. Scan your computer

After installing the antivirus, scan your computer for viruses that may be hiding there. This process can be fast or last several hours depending on the type of analysis selected (surface, depth, euristic, etc.) and the quantity of files on your hard drive.

Step 6. Schedule automatic scans

It is best to schedule the antivirus to automatically scan your computer. Look for the option "configure antivirus" and schedule the software to perform automatic scans at a time of day or night when you are not using the computer. Weekly analysis is sufficient for normal use. If you download a lot of files and programs or go to risky websites, schedule more frequent scans.

Step 7. Download Windows updates regularly

Windows offers constant security updates. Some of these updates are intended to strengthen the security of your system by correcting exploitable vulnerabilities in the program. If you update Windows regularly, your computer is better protected.

Method 2 of 3: With macOS

Install an Antivirus Step 8

Step 1. Understand what an antivirus is useful for on a Mac

macOS is much better protected than Windows. This stems from the way the operating system itself was designed. Mac is less popular than PC, which is also a reason why there are fewer viruses created for Mac. In recent years, the number of Mac users has increased dramatically, but it is still a much safer operating system than Windows, the vast majority of viruses are created for the latter.

The primary use of an antivirus with a Mac is to prevent the proliferation of malware and viruses. Even if your Mac isn't infected with viruses, it can pass them on to other computers that aren't fortunate enough to have the same protection. Malware and viruses are easily transmitted through email

Step 2. Choose an antivirus

Since you have very little chance of getting infected with a virus from a Mac, it is not really necessary to purchase an antivirus to protect your machine. You can download a good free antivirus designed for macOS from an official site.

Step 4. Download updates for Mac

Regularly download updates for macOS to ensure that your system is protected as effectively as possible. Apple issues frequent security updates to address vulnerabilities in the program.

Method 3 of 3: With Linux

Install an Antivirus Step 12

Step 1. Understand the usefulness of an antivirus with Linux

Of the three main ones, Linux is the operating system best protected against viruses and malware. This is due to the design of the software itself and the fact that there are far fewer users. With Linux, you install the programs from a download center, the software is all checked and comes from the official site, making the proliferation of viruses very unlikely.

With a Linux operating system, the main use of an antivirus is to prevent the proliferation of viruses and malware by transmitting them to other computers. Even if your machine is not contaminated, you can transmit infections to computers that are less protected than yours. Malware and viruses are easily spread through e-mail

Install an Antivirus Step 13

Step 2. Download an antivirus

Most Linux antiviruses are freeware. Consult your download center to select from the library available software that suits you. The programs in the library are all verified by members of the Linux community and use very little of your system resources.

By updating your version of Linux regularly, you are also updating your programs and you have the best possible protection by fixing any system vulnerabilities that may exist. Check that the update options for your version of Linux are configured correctly and that they are performing correctly.
