New Avast version 2015 R4 has been released, and you may be wondering how to update your Avast Antivirus. Luckily, you can do the program update completely for free. With some other vendors, you would need to actually pay for the update, but not with Avast.
You can perform the update process using one of these two options:
- Run the in-product update, which is pretty straightforward and it only takes five simple steps which are explained below.
- Alternatively you can download the latest Avast 2015 version and run the installer at the top of your current version.
1. Begin the Program Update Process
If your version is out-dated, or if you aren’t sure, you can easily check to see if there is a newer one available. Open your Avast and go to ‘Settings‘ » ‘Update.‘ In the tab ‘PROGRAM,‘ you can check if your Avast is outdated or not – if so, you will see a message ‘A new version of the program is available!’. To begin the actual update process, simply click on the ‘Update‘ button.

You can also perform the program update via the system tray. There, you will find the orange Avast icon, right-click on it, select ‘Update,‘ and then ‘Program.‘

Sometimes, Avast will display a yellow pop-up message informing you about the new program version, and a direct ‘Update now‘ button.

2. Select the Update Type
Before the update process starts, you may get asked to select the type of the program update:
- Essential update – Standard update of the Avast Free Antivirus with no product change
- Essential update + Internet Security – Update which switches you to Avast Internet Security which you may try free for 20 days
It’s totally up to you which update you pick. However, it may be useful to checkout all the advanced features for secure shopping in Avast Internet Security, for free.

3. Confirm the EULA
Usually, with a new version, the End User License Agreement (EULA) is also updated. You may read it in full PDF version, but in short – Avast collects information from your computer and may share it with a third party; on the other hand, that information can’t be used for targeting or identifying your person. If you agree and accept the new EULA, just click on the blue button ‘Continue‘.

4. Finish the Update Process and Restart Your Computer
Wait until program finishes the update, and after that just restart your computer. You can do it by yourself or by clicking on the button ‘Yes‘ after the program update is downloaded. Do not try to use Avast before you restart your computer.

5. Enjoy Peace of Mind with the Latest Version
That’s it, now you should be running on the latest version. You can check that by going to ‘Settings‘ » ‘Update,‘ where you shouldn’t see any message about new versions available, though you will always see the ‘Update‘ button.

Free Download of Previous/Older Version of Avast
If for any reason you would like to go back to your previous version, you need to uninstall the program, get the installer for the previous version, and install Avast again. Getting the installer for your previous version may be quite hard as Avast officially offers only the latest version for download.
However, you can still find older versions on some servers like FileHippo (see right column called “Old Versions”). Older Avast version are still receiving the virus definitions updates, same as the latest one.

Avast Program Update Release History
Cover every Avast program update which has been released would take many pages. But if you want to check it, you can find it on the official Avast forum. You will find there release dates and changes from 2012 (version 7) to the actual one.
The Difference Between Update and Upgrade Explained
Some users are confused with the terms update vs. upgrade. So here is the difference:
- Update – Means actualization to the latest version of the same product. In the case of Avast products, it’s completely free.
- Upgrade – Means migration to a better product from the same vendor. Obviously, upgrades are paid.
Although we have used Avast Free Antivirus 2017 screenshots in this article, these steps are also applicable for all Avast Antivirus solutions (i.e. also for Avast Pro Antivirus, Avast Internet Security, or Avast Premier) running the latest version available.
Steps are relevant for all Windows versions – Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10 (including Anniversary Update).
