I could not see any relationship between avast! and a CD Burner (Nero / NTI).
I have, in the past, both Nero and NTI and they don´t work very good when togheter at the same computer (this is not a law, it’s my experience…). Easy CD Creator (Roxio) works poorly bad in my XP system (mess everything)…
But you seems to have a driver error not a trouble with avast!
Do you use InCD (from Nero)? I use without trouble… but never togheter with NTI.
Do you have a firewall or proxy filter? The connection to the Internet may be related to these applications and not avast!
Why do you have NTI connected to the Internet?
Remember, I’m avast! user not avast! team member ;D
