This step-by-step manual explains how to install avast! Free Antivirus 2014 (version 9). 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 default set of componenets (including SecureLine VPN, GrimeFigther, and Software Updater)
  • Custom installation (for advanced users) – You can select which components, shields, and languages you want to install

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 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 third step you actually do not have to do anything. You can just sit and watch the progress bar how avast! is creating system restore point and how the avast! files are being copied onto your computer. Also you can read useful information about avast! features.

    My wife wants to use Avast for free antivirus protection. Does she have to give credit card information?

    • Reply

      Hi David,

      Not at all! Just download and install it. After 30 days she just have to register (via Facebook or e-mail). No billing details are needed.

    Is it normal that avast has been downloading for about 16 hours now and I am unable to access ANY websites at all whatsoever while it’s downloading? My system did the Windows 8.1 update, removed avast, advised me that windows defender needed to scan my PC (I didn’t acknowledge this suggestion). I came straight here and started the download process for avast. After several hours, I just rebooted my PC thinking something was wrong. When I brought it back up, it then resumed the download on its on as soon as I opened an internet session. 16 hours ago. If I dare try to access another website either via Firefox or Explorer, I get a constant wait, then a message that the page can’t be displayed. I have other devices that run off of my wireless internet and they are working fine. It’s just this laptop – after the Windows 8.1 update (which had I been given a choice, I would have declined).

    I am trying install Avast free in an older computer and the continue button is off the screen. I can’t change the screen resolution or the size of the Avast picture that is displayed on set up

      Hi Billy, Have you tried to hit ‘Enter’ on your keyboard to make the installation process continue?

    For those of you with windows 8 that are getting the 00000005 error, or having problems installing avast in general,you need to download the uninstaller from the McAfee website and run it to completely remove McAfee. The uninstall tool in your computer settings is not enough to completely remove it and avast will not install with it still on there. I learned the hard way. Jim

    I have been seeing/reading blogs/posts on how to install Avast 2014 which is the newest version solving the Windows 8.1 upgrading issue.

    It says if I have windows 8.0, I need to update Avast first before upgrading to Windows 8.1

    What if I already upgraded to Windows 8.1 without Avast and wanted to install Avast 2014 now that it’s in Windows 8.1? Or do I need to do or get anything else before doing so?

    Well, it sounds like a silly question, and it’s telling me it’s OK to do so but I want to be completely sure because I don’t want to end up in the forums complaining and asking how to undo or solve problem with this regard.

    Many thanks in advance…

    especially that there has been tons of posts regarding compatibility issues on Windows 8.1 and Avast

    I was just billed for avast and I did not authorize this charge. I want it credited to my bank account because I did not authorize it.

    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.

    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?
