Avast! Free Antivirus is one of the most well-known antivirus products.  It is a popular antivirus counting over 80 million users worldwide in 2009. Three years later had 165 million registered users in October 2011. It is one of the best antivirus products worldwide and it`s a winner of many awards like Virus Bulletin VB100 Award, Secure Computing Readers` Trust Award and many others. If you are here, you probably want to install Avast Antivirus on Window. If you will install this antivirus for the first time this article should help you. The purpose of this article as I said is to be your guide and to make the entire process as easy as possible. Keep in mind that we are using a ``custom`` installation type. Please uninstall any antivirus that runs on your PC and then download Avast Antivirus. It`s always recommended to download and install the latest version. It doesn`t matter what download web site ( reputable ) you are going to use since the antivirus files and virus database will be downloaded on your computer from a direct, safe source and the speed will be fast ( depending on your Internet Connection Speed ).  If you downloaded the antivirus, locate and open the setup file.

This is the first setup window. It says ``Welcome to avast!`` and you`re being notified that ``By installing or using the product, you agree to its User License Agreement``. Make sure that you read the license agreement. As you can see, I will choose ``Custom Install`` instead of ``Express Install``. I also chose NOT to install ``Google Chrome`` as it was already installed on my computer.

The second window will ask for the installation folder. Unless you have a good reason, leave the default installation folder and move on.

Destination directory where Avast Software will be installed

This is the configuration window and from here you can choose what to install. This is for advanced users. Unless you really know what you`re doing, leave everything as it is. Feel free to add or change the language but leave the other areas as they are.

Setup Configuration for Avast Free Antivirus

In this window you can double-check all the features, path and required space for the installation. If you need to make a change, use the ``Back`` button. Otherwise you can continue. I will reproduce the text from this window ( on your computer the configuration should be different )Setup will install the following components:

- Browser protection

Installation information in Avast Setup

The antivirus is installing, this window was not necessary but I wanted to show you the entire procedure. Be patient, depending on your computer speed it will take a couple of seconds or minutes. It took me approximately 4-5 minutes to finish. However my laptop is 4-5 years old.

Installing, please wait while Avast Antivirus is being installed

Congratulations. Setup finished, your antivirus has been installed. I strongly advise you to restart your computer, actually you are being advised the same – ``If you do not restart your computer, some components will not run correctly or may cause system failure.``

Setup Finished - Avast is now installed - Computer Restart is required

One more thing, if Avast! Free Antivirus was successfully installed on your computer you should see a similar window. Please note that it will work for a period of 30 days. Yes it`s free but you need to register your antivirus after 30 days. There is a small link - Register now. As far as I know the license should be valid for one year and then you need to register again. That`s the procedure with this antivirus.
