You probably already know that Avast Free Antivirus 2018 is totally free and you don’t have to pay a cent to be protected. At least if you’re using it in your household for non-commercial activities.

However, there is one thing you have to do within the first 30 days and each year after. Even though you will get the license only for 1 year, you can get a new one when it expires. So you can basically keep using Avast for free forever.

It’s called activation for a license key (activation code) or serial key, and it’s very simple.  It also works in any older version like Avast 2017, 2016, 2015, 2014, 8, 7, 6, 5 or v4.8. In the past, Avast was also using license files which were generated for a specific e-mail address. License files are luckily not used anymore and the only thing you need is a simple 28-character long unique code.

WARNING We strongly do not recommend using any keygen or crack you may find on the Internet. Most of them are full of malware.

If you like videos, there is a fantastic commented video manual on this page, which explains the whole activation process in a few seconds. And don’t worry if you are not able to retrieve your own license key, we have got one for you at the end of this tutorial.

Activate Your Avast and Get Your Free License Key (Activation Code)

Step 1 (out of 4) – Open Avast and Start the Activation

Start by opening your Avast user interface. You can do this in many ways:

  • Find Avast icon on your desktop
  • Find Avast program in your Start menu
  • Find Avast icon in the Windows system tray (bottom-right corner). It is usually hidden, so you need to click on the top arrow

When Avast user interface is opened you can activate it by clicking on the ‘ACTIVATE‘ button at the bottom left corner of the main window, ‘Activate‘ link in the status area, or by going to settings (bottom left corner) » ‘Subscription‘.

    Avast they are the Best I recall version 4.6 and I was living around some hackers which gave them a hard task,I was very well protected at the time it was around 2006-2007 and things were different here in australia online with mostly us websites and very limited australian websites etc I was all over the world looking at all the available Virus security and Avast was always up there on the top. Well done AVAST thanks for all the protection

    My dad has a free version and an old browser. When I click “select” nothing happens. How can I get a free key (like I have in past years)?

    I have been trying to update my avast free antivirus which expired on April the first but to no avail. I get the “The online content is unavailable, please check your internet connection” which is strange becouse my internet connection works perfectly, what am I supposed to do now?

      before you setup Avast change the pc date to let say 01-01-2030, than setup the program, it will ask you if you want to install an old version, press the positive key. after the avast is installed change to the correct date, your license will end 90 days after the above date. have good luck
