Good evening bob3160,
Thank you for jumping in to help on this matter. I have indeed read this article prior to coming to the Avast forums. I have fixed this issue, with a degree od certainty, but there are still remnant left that pop up here and there. I wouldn't wish this nightmare on anyone.
Once again, thank you for bringing more information forward. Perhaps some good will come from all of this.
Regards,
Darcy
