Win 7 Pro x64. AIS 18.4.2338.
Ever since the install of the latest version my NIC takes an age (5+minutes) to get a new IP address lease (DHCPNACK message).
During this time (of course) Avast cannot launch its emergency update task.
When it finally succeeds I can browse, email, etc. just fine. The PC is routinely rebooted daily.
I have tried: repair, clean install (each twice), flush ARP cache, repair Winsock, flushdns & all the usual DNS fixes. No go.
Any ideas anybody?
TIA
