Spam is unsolicited e-mail advertising typically sent to a large number of users. These types of messages can cause loss of time and resources. The anti-spam protection will help you keep your Inbox free from these types of messages.
It is possible to enable and configure this protection from the Automatic protection area in the control panel -in the program window-, or by clicking on the Platinum Internet Security icon in the Windows system tray (next to the computer clock).
