What is a VPN?
A VPN (Virtual Private Network) functions as a private tunnel through the internet which encrypts your data and secures your connection when using public Wi-Fi connections such as those in cafes or airports.

Why is my internet connection slower when I connect to SecureLine VPN?

How do I uninstall SecureLine VPN?
Can I use SecureLine VPN without installing Avast Antivirus?

Is SecureLine VPN licensed separately from Avast Antivirus?
Yes. SecureLine VPN is an extra service and requires a separate license to use. An Avast Antivirus license does not activate SecureLine VPN.
What should I do if my activation is unsuccessful?
SecureLine VPN requires a separate, paid license to use it. If you are using Avast Antivirus, ensure that you have purchased and activated a license for SecureLine VPN. If the activation is unsuccessful, you can submit a ticket to the Avast Support Team for assistance.
How do I get started using SecureLine VPN?

How can I prevent the WebRTC leak on my browser?
WebRTC is a feature that various browsers such as Google Chrome and Mozilla Firefox apply because it supports B2B applications such as voice calling, video chat, and P2P file sharing without the need for plugins. In Windows, macOS, and Android systems, this feature potentially enables IP addresses to be visible even when you are connected to a VPN such as Avast SecureLine VPN.
We are actively looking for a solution to this issue. In the meantime, protect your privacy by blocking or disabling WebRTC. You can also avoid this vulnerability by using a browser which does not apply WebRTC (such as Safari or Internet Explorer).

Why do Gmail and Live Mail send me suspicious activity alerts when I'm connected to SecureLine VPN?
If you use a different location when you connect to the internet via SecureLine VPN, Gmail and Live Mail may detect this change. You may receive an email reporting suspicious activity, and will be asked to change your password if you think someone in a different location has accessed your email. Verify the VPN location you selected to ensure your security.
Why do certain websites claim that I'm connected to a different city than the city I selected as my VPN location?
Websites often attempt to identify the location of their visitors from their IP address, a process called IP geolocation. IP geolocation uses a database that pairs together IP address ranges and geographical information. The information in this database can be inaccurate for several reasons:
- Avast does its best to provide accurate information to the IP geolocation databases, but the database providers may take extra time to update the location.
- The website may be using an outdated version of the geolocation database.
- Some major websites (Google, for example) maintain their own databases based on what user traffic came from the IP address in the past.
- In certain locations, we rent dedicated servers to provide SecureLine VPN, and the IP geolocation databases are updated by the server provider on Avast's behalf. Because Avast is a Czech company, these providers may indicate the location as Czech Republic. When this occurs, we work with the providers to update the information with the correct locations of our servers.
Why is SecureLine VPN a paid product when other VPN services are free?
To support the continued development of SecureLine VPN and give you access to the best VPN technology, SecureLine VPN is a paid product.
Many free VPN services sell your data to 3rd parties, place ads and videos into your browser, and slow down your internet connection.
SecureLine VPN never compromises user experience or privacy. We do not share or sell your data to 3rd parties, nor do we monitor your internet activity. SecureLine VPN does not interfere with your internet connection and is completely ad-free.
