The Real Time Scanner also scans the system memory on start. If you launch a program
or file which creates destructive anomalies, then the scanner blocks it and alerts you
immediately - giving you real time protection against threats.

You also have options to automatically remove the threats found during scanning and to
update virus database before scanning. It is highly recommended that you enable the Real
Time Scanner to ensure your system remains continually free of infection.
