Avast Free Antivirus - The best free antivirus

Avast Free is an antivirus created by the company Avast Software (formerly Alwil Software) founded in 1988.
Currently, 230 million users trust Avast and the latest version of Avast (2016) is also compatible with Windows 10.

The advantage with Avast is that the paid features tend to become free over time.

1. Installation

At the beginning of the installation, Avast offer to install the web browser "Google Chrome" (at bottom of the window).
Uncheck the 2 boxes at the bottom if you don't want to install Google Chrome, then click "Customize" below the "Install" button.

As you can see, Avast comes with lots of features :

  • File Shield : to scan files on your computer and detect viruses through real-time protection.
  • Web Shield : real-time protection against malicious sites. Can also block a virus when you download a virus on Internet.
  • Mail Shield : real-time protection to block viruses received or sent through an email client (eg Outlook, Thunderbird, ...)
  • Browser protection : an extension that is installed in your web browsers (Mozilla Firefox, Google Chrome and Internet Explorer) to protect you against malicious sites and tracking.
  • Software Updater : keeps known programs and plugins up to date. You are notified when an update is available for your programs.
  • Remote assistance : allows you to help a person, having Avast also through a remote control solution as Teamviewer.
  • SecureLine : paid option (requires subscription) that allows you to secure your connection. Useful if you often connect on open wifi or public wifi.
  • Cleanup (formerly : GrimeFighter) : paid option (requires subscription) allowing you to optimize your system. Similar to CCleaner.
  • Rescue Disk : lets you create a bootable CD Avast to perform an antivirus scan on a PC that will not boot.
  • Browser Cleanup : allows you to analyze your installed extensions in different web browsers (Firefox, Chrome, ...) to detect any malicious extensions.
  • Desktop agent : Displays the status of the antivirus on the desktop.
  • Home Network Security : allows you to analyze your local network to detect security problems.
  • Passwords : secure password manager. We recommend using "KeePass" which has the advantage of being multi-platforms and protects you from being tied to a specific antivirus.

In summary, given that some features are not free, uncheck the following features :

  • SecureLine
  • Cleanup

These options are useless :

  • Desktop agent
  • Passwords

Avast is installed.

It is possible that avast offers his free antivirus "Mobile Security & Antivirus" for Android smartphones and tablets.
If you don't have an antivirus installed on your smartphone or tablet, install it. It's free.

Otherwise, click on the link "No, I don't want to protect my Android phone".

Avast Free is displayed.

2. Register

As you can see at the top of the program, there is a button "REGISTER".
To use Avast Free for one year for free, you have to register for free.
Click this button and select the standard protection (or essential or free, depending on what is proposed).

Enter your e-mail address and click on "Register".
Note : as shown in the image below, you can renew your free license as many times as you want. This means that every year, Avast will warn you that your version of Avast is about to expire and you will only need to renew it for free.

Avast invites you to switch to the paid version, but there is always a button or a link to stay with the basic protection (or standard, essential, free, ...)
Here, click "No thank you. Keep my basic protection".

Now, Avast is registered and will work for one year.
After this period, you will need to renew it for free.
