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 a flash drive. For those who like videos, there is a fantastic commentated ‘Video Manual‘ 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

Locate 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. Your 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.

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 or not you want that product to be installed.

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 short – AVAST collects information from your computer and may share it with a third party; on the other hand, this 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 secondstep, you actually do not have to do anything. You can just sit and watch the progress bar show Avast being downloaded, creating a system restore point, and the Avast files being copied onto your computer. Also, you can read useful information about the new Avast 2015 features like Home Network Security.

    I want to install Avast Free on a second computer. Should I download as a new install or should I go into my account and download & install it from there. Or does both methods get the same results with them both linked to one account?

    It’s telling me that there was an error while completing setup process

      Hi Aniekan,

      It depends if you are using the online (around 5 MBs) or offline installer (around 150 MBs). The online does need an Internet connection as it downloads all the files during the installation process. Offline obviously doesn’t need an Internet connection.

    At the regular installation site I was told that there was not enough disk space on Drive C. This proved correct and so I installed an external Hard Drive. Avast will not download to this drive E. Any suggestions?

    A patron has an Asus laptop with windows 8. When I tried to download Avast 2015 it says, “unable to download please visit windows store.” I could only find the Avast guide in the windows store. Please advise!
