I had Avast! Secureline installed using the free version. I did not want this installed and I have uninstalled it. Now the PC is using Teredo to funnel all IPv4 through IPv6 which limits my access on websites. I tried removing it several ways but have not had any luck. I have uninstalled the device in the device manager and it keeps coming back. I have all the mini adapters disabled but can't uninstall them. The PC is a Win7 64bit with SP1. I have several PC all thou a single router. Each PC has a static IP and all the the same external IP which starts with 98. (right now) the PC with the problem has an IP that starts with 108. I am pulling my hair out on this one! Please help. I've ran MiniToolBox and have the report for that.
