New Avast version 2017 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:

Quick Summary

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 Open your Avast and go to ‘Settings‘ » ‘Update.‘ In the tab ‘PROGRAM,‘ you can check if your Avast is outdated or not – if so, you will see a message ‘A new version of the program is available!’.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.

2. Select 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.

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. Older Avast version are still receiving the virus definitions updates, same as the latest one.

Here are the free download links for the popular older versions which are still working

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.

Additional Notes

    I just installed my license for the paid version with internet security and clean up. I now cannot access my school website, or even the gmail website. I get an error stating “connection timed out.” I’ve tried adding the school site as an exception, but no change. When I temporarily disable Avast, I can access everything fine. Please help! I’m an online student and need access to these things, but don’t want to have wasted nearly $50 on protection for it.

    Thank you!

      Hi Jared,

      Sounds like you are having issues with the HTTPS scanning. First try to update your Avast to the latest version. If it won’t help go to settings » Active Protection » Web Shield » Customize and uncheck ‘Enable HTTPS scanning’ » OK.

        I cannot see the option “uncheck ‘Enable HTTPS scanning’ » OK”

    My avast antivirus as completely blocked me from the internet ……I don’t know what to do

    Ran the free avast program for years, and I installed an avast update on 10/13. Immediately it identified several programs I need as “threats” and prevented them from running. Shut down avast, removed it from the computer and spent time uninstalling and reinstalling several programs. Google chrome doesn’t freeze as much with avast gone but that could be unrelated. Currently using AVG trial, when that expires undecided. Not sure if I would try avast again.

    Avast says I don’t have any Internet connection when trying to update the application. But, here I am typing away so obviously I have Internetconnection. There is no Firewall blocking the traffic and there used to be no problem before. Something has suddenly changed.

    I just upgraded to Pro after many years of using the free version. After the required reboot, I could not type my Windows 8.1 password (or anything) into the opening screen password box! Startled the dickens out of me. After some clicking around on this I discovered the Ease of Access selection which enabled me to open the on-screen keyboard. Using this I succeeded in getting the system to accept my password. Searching this problem using Chrome I found similar complaints dating back several years.

    I’m afraid that if I have to reboot I will experience the same problem – being locked out of my system would be a disaster.

    Any suggestions will be appreciated.

    I have upgraded my free avast to the new version to get rid of the “Avast Web Shield has blocked a harmful webpage or file” 3″ x 3″ block it still pops up every second, its annoying and in the way. Why do I need to know that it blocked something? It also is making it hard to open files as it says my “security setting” won’t allow it. I have changed it numerous times to no avail. I think it is the pop up. How do I get this off? I’ve looked into numerous ways listed online but nothing is working. Help!
    Thanks
