If I set my Avast Free to ‘Scan All Files’ instead of some extensions and set its Firewall to ‘Ask’, these settings will be transferred to Avast One if I install Avast One on top of Avast Free. I find that these settings work very well in Avast One.
Please have ‘Scan All Files’ setting and Firewall Ask setting in Avast One instead of us having to install on top of Avast Free first.
Malware may hide in file extensions such as jpg so it is better to scan all extensions. Firewall Ask mode to ‘Once’ or ‘Temporariy’ can tell Avast One to remove one time or obsolete apps from Firewall.
