access one or more memory registers to execute the first set of instructions; and
access one or more memory registers to execute the second set of instructions.
3. The computer program product of claim 1 , wherein the environmental data comprises an identification of a first condition to be met for executing the first logical path and a second condition to be met for executing the second logical path.
4. The computer program product of claim 1 , wherein the first and second sets of instructions are executed from a sandbox environment.
5. The computer program product of claim 1 , wherein the evaluation by the malware handler module of the first and second sets of information is performed by execution profiling.
6. The computer program product of claim 1 , wherein the instructions are further operable, when executed, to:
start a timer prior to executing the first set of instructions to follow the first logical path; and
terminate execution of a logical path at an expiration of the timer.
7. The computer program product of claim 1 , wherein the instructions are further operable, when executed, to:
receive configuration information identifying a number of branches from the parent node to execute; and
terminate execution of a branch after the identified number of branches have been executed.
8. The computer program product of claim 1 , wherein the instructions are further operable, when executed, to terminate execution of a branch upon detection of malware.
9. A computer implemented method, comprising:
identifying, at a logical path node, a first logical path and a second logical path;
responsive to storing environmental data for the logical path node, executing, by a processor implemented at least partially in hardware, a first set of instructions to follow the first logical path, wherein the environmental data is a parameter for executing an instruction for the logical path node;
storing, in a memory, a first set of information obtained from following the first logical path;
evaluating, by a malware handler module implemented at least partially in hardware, the first set of information for malware;
restoring, from the memory, the environmental data for the logical path node to execute, by the processor, a second set of instructions to follow the second logical path;
storing, in a memory, a second set of information obtained from following the second logical path; and
evaluating, by the malware handler module, the second set of information for malware.
10. The computer implemented method of claim 9 , further comprising:
accessing one or more memory registers to execute the first set of instructions; and
accessing one or more memory registers to execute the second set of instructions.
11. The computer implemented method of claim 9 , wherein the environmental data comprises an identification of a first condition to be met for executing the first logical path and a second condition to be met for executing the second logical path.
12. The computer implemented method of claim 9 , wherein the first and second sets of instructions are executed from a sandbox environment.
13. The computer implemented method of claim 9 , wherein the evaluation by the malware handler module of the first and second sets of information is performed by execution profiling.
14. The computer implemented method of claim 9 , further comprising:
starting a timer prior to executing the first set of instructions to follow the first logical path; and
terminating execution of a logical path at an expiration of the timer.
15. The computer implemented method of claim 9 , further comprising:
receiving configuration information identifying a number of branches from the logical path node to execute; and
terminating execution of a branch after the identified number of branches have been executed.
16. The computer implemented method of claim 9 , further comprising:
terminating execution of a branch upon detection of malware.
17. A system for executing a full logical path in an executable application, the system comprising:
a processor implemented at least partially in hardware;
a memory for storing instructions;
an execution application module, implemented at least partially in hardware, to,
responsive to storing environmental data associated with a parent node of the full logical path, execute a first logical path from the parent node, wherein the environmental data is a parameter for executing an instruction for the parent node; and
restore the environmental data associated with the parent node to execute a second logical path from the parent node; and
