The prioritized memory allocation and resource constraining tools of the latest operating systems, such as Windows 8, are used to limit the resources of low reputation software applications by forcing the use of low priority memory allocations and limiting the use of high priority memory. Other restrictions are also implemented based on application reputation.

RESTRICTING MEMORY ALLOCATION AND RESOURCE USAGE OF LOW REPUTATION APPLICATIONS
Malicious applications often utilize the system resources to “starve” other legitimate applications of resources. Using conventional tools, the user has previously been able to only completely block and quarantine files having an insufficient or low reputation. There is no current means by which the user is able to allow some resources for a specific application and block or limit other resources for the same application. Further, there is no provision to handle "medium reputation" applications or "medium prevalence" software applications.
Application programming interfaces (APIs) provide an interface for software components to communicate with each other. In some Windows operating systems, a Win32 API hooking mechanism may be used to intercept API communications between various software components. The hooking mechanism is used herein to intercept APIs, such as those that spawn processes and allocate memory. Additionally, new “nested job objects”, such as is found in Windows 8, c...
