When you will be Virus defination Manually update PTP and NTP defination not updating .

you can check this site for the latest definition for SEP modules,

 Proactive threat protection can receive updates from Internet/Internal Liveupdate server/SEPM/GUP.

You cannot update it manually.

About Proactive Threat Protection:
Proactive threat scanning provides an additional level of protection to a computer that complements existing AntiVirus, AntiSpyware, Intrusion Prevention, and Firewall protection technologies. AntiVirus and AntiSpyware scans rely mostly on signatures to detect known threats. Proactive threat scans use heuristics to detect unknown threats. The Heuristic process scan analyzes the behavior of an application or a process. The scan determines if the process exhibits the characteristics of a threat, such as Trojan horses, worms, or key loggers. The processes typically exhibit a type of behavior that a threat can exploit, such as opening a port on a user's computer. This type of protection is sometimes referred to as protection from "Zero-day attacks":
 

• "Zero-day attack vulnerabilities" are new vulnerabilities that are not yet publicly known. Threats exploiting these vulnerabilities can evade signature based detection such as AntiSpyware and AntiSpyware definitions.
• "Zero-day" attacks may be used in targeted attacks and in the propagation of malicious code.

Proactive Threat Protection also includes Application and Device Control Policies. Application and Device control is implemented on client computers using policies. An Application and Device Control Policy offers two types of control or protection over client computers:
 

• Application control
• Device control.

Is it showing us "waiting for updates" or the defs date is not new as yesterdays date? Symantec will not release updates for PTP daily.
