So i had trial Bitdefender 2013 installed, because it was to paranoid I decided to use another antivirus. During uninstall i was in safe boot with network and when i tried to connect to internet some kind of error poped up and i couldnt connect to internet. When i uninstalled it, and in normal boot I was able to connect to internet, but all programs could not use it (skype, Avast, iTunes, everything) except browsers (Opera, IE). I turned off windows firewall and defender uninstalled my new antivirus also(Avast) and it didn't help. I have an ADSL connection, where my PC is connected to my router via LAN. I also have two virtual networks hamachi and tungle, but both are disabled. Help Please!
