With your true IP address hidden, and your internet traffic encrypted, top-quality VPNs make it very difficult for ad trackers — or anyone else — to track you online. Websites won’t be able to find your IP, and while your ISP may see that you’ve connected to a VPN, they won’t be able to see the traffic itself. To cover your tracks even more thoroughly, ensure that your VPN kill switch is enabled, and use a private browser like Avast Secure Browser.
