I’ve just converted a Norton/McAfee user (a friend) to swap to Avast!
He has a question about default action when a virus is found, how to change the default action (Alerting) by the action of deleting the infected file (or move it to the chest) when running a complete scan (local disks)?
No, I believe it’s the key controling the automatic deletion of sessions in the Enhanced User Interface.
The automatic actions can be set the Professional version of avast! - in the Enhanced User Interface, by editing the corresponding task (page “Virus”).
