Can someone explain to me what is the difference between Early Launch Anti-Malware (ELAM) Protection and Boot Time Protection?
I understand that ELAM is a new feature only compatible with Windows 8. Is ELAM supplementary to Boot Time Protection or opposite or do they work together? And why is BTP by default turned off? Should I turn it on on Windows 8?
These are the official descriptions for BTP and ELAM:
Boot Time Protection
The boot time protection feature provides enhanced security level from the time you start your computer. It ensures better security by running all the necessary components that are required for computer protection as soon as you start your computer. A boot time scan is a virus scan that is run before the operating system fully loads up. This allows your Norton product to have access to all the files on your computer with no chance that they are being used by another program or the operating system.
To protect your computer during boot time, you must configure the Boot Time Protection option.
When this option is set to Normal or Aggressive, all required drivers and plug-ins start functioning as soon as you start your computer. A driver is a program containing information that the computer needs to recognize and control a device. A plug-in is an add-on for a program or a service that adds functionality to it. This option ensures higher level of security from the moment you turn on your computer.
When this option is set to Off, specified drivers and plug-ins start functioning only after a specified time delay.
If you restart your computer after LiveUpdate or a product upgrade activity, the drivers and plug-ins function normally. However, in the subsequent restart the drivers and plug-ins function normally after the specified time delay.
Early Launch Anti-Malware Protection
The Early Launch Anti-Malware Protection feature provides enhanced security level when you start your computer. It ensures better protection by running all the necessary components of your Norton product that are required to block any malware from functioning when you start your computer.
They really sound the same in different words (the first one though gets a lengthier description).
