I just downloaded Avast/home.
I can’t seem to find how to set up the scan email option. Is this an option with Avast?
What OS? What email client? What firewall? What avast! providers are you running? Normally there should be an “Internet Mail Provider” when you right click the icon and select “On-access protection control” that will allow you to select pop3 and smtp scanning.
