Unlike a firewall or antivirus program, DEP does not help prevent harmful programs from being installed on your computer. Instead, it monitors your programs to determine if they use system memory safely. To do this, DEP software works alone or with compatible microprocessors to mark some memory locations as "non-executable". If a program tries to run codeómalicious or notófrom a protected location, DEP closes the program and notifies you.
DEP can take advantage of software and hardware support. To use DEP, your computer must be running Microsoft Windows XP Service Pack 2 (SP2) or later, or Windows Server 2003 Service Pack 1 or later. DEP software alone helps protect against certain types of malicious code attacks but to take full advantage of the protection that DEP can offer, your processor must support "execution protection". This is a hardware-based technology designed to mark memory locations as non-executable. If your processor does not support hardware-based DEP, it's a good idea to upgrade to a processor that offers execution
The Processor supports DEP Natively with SP2 (AMD Athlon 64).
