Pourquoi faire confiance à ce guide ?
I have run Avast SecureLine VPN for eight months across Windows, Mac, Android and iOS.
Every step here comes from the app itself, not from marketing pages.
Avast VPN is one of the better known VPN services on the market.
Most people switch it on once and never touch the rest of the app.
This guide shows you how to use Avast VPN properly, feature by feature.
Étape par étape, avec captures d'écran et conseils de pro.
Tutoriel Avast VPN
This How to Use Avast VPN tutorial walks through the whole VPN app, from the installation process to the settings most users never open.
Avast VPN
Hide your IP address and connect to the internet via secure Avast VPN servers in almost 60 locations. Bank-grade AES 256 bit encryption, a Kill Switch and Smart VPN mode come standard. Start free trial access today, no card charged until it ends.
Premiers pas avec Avast VPN
A virtual private network works like a private tunnel through the internet.
It encrypts your traffic and swaps your real IP address for one belonging to a VPN server.
Here is my own walkthrough of the app:
Passons maintenant en revue chaque étape.
Étape 1 : Créez votre compte
Open the Avast site and click Start Free Trial.
Enter your email, create a password, then enter payment details to unlock the trial.
The free trial runs 60 days on desktop and seven days on mobile appareils.
✓ Point de contrôle: A confirmation email lands in your boîte de réception.
Step 2: Download and Install the VPN App
On Windows or Mac, download the installer from your account page and run it.
On an Android device, grab the app from the Google Play store; iOS users take the App Store.
Mac and iOS ask you to allow Avast to add VPN configurations during the installation process.
Voici à quoi ressemble le tableau de bord :
✓ Point de contrôle: The main screen shows a large power slider.
Step 3: Switch the VPN On
Click the red OFF slider so it changes to green ON.
That is the whole trick to connect to the VPN on any device.
It works over any wired or wireless internet connection.
✅ Terminé : Vous êtes prêt à utiliser n'importe quelle fonctionnalité ci-dessous.

Voici comment l'utiliser étape par étape.
Étape 1 : Confirmer le chiffrement

Step 2: Turn On the Kill Switch
The Kill Switch blocks your internet connection if the VPN drops.
Nothing leaks while the tunnel reconnects.

Voici comment l'utiliser étape par étape.
Step 1: Install AntiTrack
Add AntiTrack to the same computer running your VPN client.
Step 2: Turn On Fingerprint Masking
Enable masking so trackers see scrambled browser data.
A virtual private network hides the IP address, not the fingerprint.
Voici à quoi cela ressemble :
✓ Point de contrôle: The dashboard lists trackers blocked this week.
Étape 3 : Examiner le rapport
Open the weekly report to see blocked tracking attempts.
✅ Résultat : Your online privacy holds up even against fingerprint tracking.

Pick a weekly scan time when the computer is idle.
✅ Résultat : Malware defence and the VPN app cover the same device.
💡 Conseil de pro : Windows 11, 10, 8 and 7 editions — Basic, Home, Premium, Professional, Enterprise, Ultimate Service Pack 1 — all run these apps.

Voici comment l'utiliser étape par étape.

Erreurs courantes à éviter avec Avast VPN
Mistake #1: Expecting a Free VPN Inside Antivirus
❌ Faux : Assuming the free VPN ships with Avast Premium Security at no cost.
✅ À droite : Buy the separate paid subscription, since SecureLine VPN is billed on its own.
Mistake #2: Forgetting the Trial Bills Itself
❌ Faux : Letting free trials lapse and getting charged on day one of the plan.
✅ À droite : Cancel inside the trial window, or claim the 30-day money-back guarantee.
Mistake #3: Staying on One Overloaded Server
❌ Faux : Keeping the same server location while streaming stutters.
✅ À droite : Connect to a different city nearby, or pick a streaming server.
