This step-by-step manual explains how to install Avast Free Antivirus 2015 (version 10). It assumes you have the software already downloaded and ready to install on your hard drive or external device like flash disk. For those who like videos there is a really great commented ‘Video Manual‘ down on this page.

Avast antivirus system requirements are nothing special and really everyone meets them these days, but if you’re not sure you can check them here.

1) Run the Setup File and Select Installation Type

Locale the file called ‘avast_free_antivirus_setup.exe‘ or ‘avast_free_antivirus_setup_online.exe‘ on your computer and start the three-step installation. If the install wizard is not in your language you can change it in the top-right corner. Selected language will also be the one in which you will have the Avast user interface. Though you can change the language anytime later in the program settings.

On the first screen you have to choose the type of installation

  • Regular installation (recommended) – Avast will be installed with the default set of components (including SecureLine VPN, GrimeFighter, and Software Updater)
  • Custom installation (for advanced users) – You can select which components, shields, and languages you want to install. This is useful when you don’t want to install SecureLine VPN or GrimeFighter for example

Unless you are an advanced user, we recommend to go with the regular installation.

At the bottom of the first step Avast usually offers some additional products like Google Chrome, Dropbox, or Avast EasyPass. So be sure to check this option as well and decide whether you want that product to be installed or not.

2) Read and Accept End User License Agreement (EULA)

In the second part of the first step you have to accept the Avast End User License Agreement (so called ‘EULA’). You may read it in the full PDF version but in a short – AVAST collects information from your computer and may share them with the third party; on the other hand those information can’t be used for targeting or identifying your person. So really no big deal. If you agree and accept the new EULA, just click on the blue button ‘Continue’.

3) Actual Installation Process

During the second step you actually do not have to do anything. You can just sit and watch the progress bar how Avast is being downloaded, creating system restore point, and how the Avast files are being copied onto your computer. Also you can read useful information about the new Avast 2015 features like Home Network Security.

    I updated Avast Free Edition on my wife’s laptop via FileHippo – she is running Windows 8.1. Now Avast is blocking her access to Paypal! What’s going on and how do I tell Avast that Paypal is OK?

    I’ve been trying to download and install the 2014 Free Avast for days now. Downloading the software seems to go ok as does as the first part of the installation. However the process takes a very long time and after about 10+ hours of “installing” Avast, the program stops. At this point I then receive a note that says “Installation unsuccessful” instead of getting the “Thank you for installing Avast” as pictured above. I am using an older computer with windows xp on a dial up connection. I have tried deleting and then downloading and installing the product several times now all with the same results.
