Messages to send
Select the events for which you want Sophos Anti-Virus to send messages. Scanning errors include instances when Sophos Anti-Virus is denied access to an item that it attempts to scan.
Sophos Anti-Virus does not send messages for threats that are detected by web page scanning because the threats are not downloaded to your computer. Therefore, there is no need to take any action.
