Hi ,
I had the internet sharing problem with avast, but i have found a solution and would like to share it.
I had Kaspersky antivirus installed, i changed to Avast! and suddenly my internet sharing stoped working, i searched the internet but all users solved it by re-installing the older version (v.4xx), this was not a solution, so i kept trying to solve this problem until i found it and would like to share it.
I have Avast 5.0.677 .
1- Go to the Avast! user interface
