// How to use Avast License Key files //
Latest Working Method:
- Open Avast product, and enter “Menu/My licenses“
- Click “Enter a valid activation code“
- Click “Use a license file“
- Open the corresponding license file (.avastlic)
- Select the type you’d like to use on your computer from multiple licenses
- Click ‘CONTINUE‘
- Restarting computer may be required
- Done
*** Every time you switch to or activate another license, do wait for its “Activating…” action to finish (i.e.: upgrading/downgrading the program files and title), and make a system restart to make it effective. Otherwise, the unmatched program title and license will confuse you a lot.

Last Working Method:
- Download and install Avast Free Antivirus, Pro Antivirus, Internet Security, or Premier from official site
- Run the “Host Blocker.bat” as administrator or add the following lines to your hosts file manually:
- 127.0.0.1 75.126.120.203
- 127.0.0.1 46.4.58.71
- 127.0.0.1 46.4.62.150
- 127.0.0.1 46.4.28.80
- 127.0.0.1 www.avast.com (may be removed by Avast)
- 127.0.0.1 www.ns2.avast.com (may be removed by Avast)
- 127.0.0.1 www.pns.avast.com (may be removed by Avast)
- Download and double click the license key file to import any license to your liking
- Done
Older Method:
- First of all, you must uninstall any previous installation of Avast product using the Avast official removal tool – Avast Uninstall Utility (AKA: Avast Antivirus Clear, Avast Uninstall Tool, Avast Clear for short)
- Download Avast Free/Pro Antivirus/Internet Security/Premier from official site, and install it as trial
- Download and double-click the license file (.avastlic) to import (give it seconds to minutes for initialization), until you can see the “Valid until:” field has a date value, click ‘Activate‘ button
- Done, enjoy (it maybe needs a restart to finish upgrade and license update)
// Prompts //
- These license keys for Avast are valid up to 2023… if expired due to key blacklisted some day, do not worry, just give me one mail to notify, and another new keys will be updated as soon.
- In some situations, when you import or double click the license key file to activate, it may get stuck out there for about 1~3 minutes. Don’t worry, after that, everything will go normally.
- AVG and Piriform are all subsidiaries of Avast now
