It could be other things other than the No Proxy that tdiddy mentioned, resolved his problem.

  1. avast! Program Settings (right click the avast ‘a’ icon), Update (Connections), Proxy… button, select the Direct connection (no proxy) option, see image.

OR

  1. What is your firewall ?
    Does it allow avast.setup internet access ?
  • If it does delete the entry for it and do a manual update (right click the avast ‘a’ icon, select Updating, iAVS Update), this should force the firewall to ask permission again.
