Avast Free Antivirus Review

Once you’re ready to try the Avast Free Antivirus on your system, you need to get ready for the installation procedure. We performed a thorough analysis of the application and present our detailed review in this article.

Installation Process

Avast download page
It is easy to install the Avast Free Antivirus on your PC. The speed of installation is a bit slow, in comparison to other antivirus software. Our Score: 8/10.

Visit the official website of Avast Antivirus and click on Download Free Antivirus button to begin the download of the installer file. Once you’re done with the download, double-click the .exe installer file to begin the installation.

Avast Free Antivirus Installer

You will be prompted to click on ‘Install’ button or customize the process. We recommend proceeding with the usual installation since this is the best way to get started with all essential features. The ‘Customize’ option provides an additional step of choosing the installation location.

Avast Free Antivirus Installation

The software would then take some time to finish the installation, during which you shouldn’t turn off your PC.

You will next be greeted with the welcome screen, which will pop up when the installation completes successfully.

Avast Free Antivirus Installation

We found that the software displays two windows simultaneously upon completion of the installation. The software would prompt you to turn on active protection. The application, by default, launches in the Passive Mode’. We recommend clicking on Yesto turn on active protection since this is necessary for the software to continuously monitor and scan the system for potential threats.

The next screen warrants attention. Many antivirus software allows the user to choose, at the time of installation, if they’d like to share information about themselves and their system usage. However, Avast takes a different approach and enables this option by default. However, users can disable information sharing by unchecking the option ‘participate in data-sharing’ in the Settings menu.

User data sharing Avast Free Antivirus

We didn’t quite like the way Avast hides its other tools and standalone software that, often, require users to pay for them, under every nook and corner of the software. For instance, immediately after the installation, the user is prompted to install Avast on their smartphone too. This is a free software, however, and can be given a try if your phone lacks malware protection.

Avast Free Antivirus for Mobile

The user is finally faced with the home screen, where all controls and essential antivirus functionality is placed. We recommend clicking on the Run Smart Scanoption after the installation to scan your system for potential malware upfront.

The Avast Free Antivirus is exceptional as far as its user interface is concerned. The design is minimalistic in nature with near-zero redundancy, which implies all essential features are easily accessible and do not repeat throughout the software.

Click on the small bell-shaped icon on the top right side of the screen to open the ‘Notificationssection. This is a great place that combines all important alerts and notifications on one, single screen. This is a great feature that helps avoid visiting several different sections of the software for vital system statistics and alerts. Click on the ?icon on the top right side of the screen to bring up the Help menu.

Avast Free Antivirus help

This is another great feature we liked in the Avast Free Antivirus, which is commonly missing in other software. The Avast places all important, frequently asked questions under the ‘Help’ section, allowing users easy access and resolution to queries without ever leaving the software interface. A commendable effort indeed!

Clicking on the Settingsbutton on the bottom left of the interface brings up the settings screen, which is the go-to place for customization of the various software options. By default, the screen begins with the Generalsection, which is where you can set the interface language and customize sounds, alerts, notifications, and other such vital options.

This is where the blocked viruses and other malware are quarantined. A great feature provided is that you can add files you think are malware yourself here! These threats are safely locked up in a vault so your PC stays secure.

The Wi-Fi Inspector monitors your internet connection. It proactively scans routers to ensure they function without problems. What’s more, you’ll even be able to see if any unknown devices are connected to your network, thus helping you stay away from hackers or unwelcome users. We recommend clicking on Network Scanbutton once in a while to ensure your network is protected.

This is a very welcome feature, which is an often overlooked aspect of security design. The Software Updater will point out pending updates to the software installed on your PC. Most updates to software address security vulnerabilities and ensuring that your PC has all apps up-to-date is crucial to overall system security.
