I agree that the problem seems to be originated from the fact that Win continues to use somehow the Secureline “virtual” adapter(s) even after disconnecting. I would suggest to clean completely Avast (with the tool or Revo Unistaller + plus a manual search for leftovers :wink: ) … then look if some Securline TAN adapters (if I remember well they are called like this) are still installed and remove them! At the beginning of Avast v9 I had a lot of problems therefore I switched from v9 to v8 tens of times, then I discovered there were about 5/6 virtual adapters left by Avast in the system… this might the cause of your issues (please note that by that time I had and XP SP3 machine, thus it might be different from Win 8) … good luck! hope this helps! 8)
