Hi.
I'm using Avast Premium Security on iOS and when I have both the Wi-Fi protection and Web Protection enabled, web pages load extremely slow, often also fail to load.
I checked what DNS server I am using when I have both enabled using safer.com and dnsleaktest.com and it was telling me I am using Cisco OpenDNS servers and my ISP DNS servers so the DNS is also leaking.
If I disable web protection, then web pages load at normal speed and safer.com and dnsleaktest.com telling me I am using the Avast DNS server only.
I do experience this with both 4G and Wi-Fi connection.
Thanks.
