Methods and apparatus for application isolation

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code to cause the processor to:

• execute each application from a plurality of applications within a different virtual environment from a plurality of virtual environments to isolate each application from the plurality of applications from the remaining applications from the plurality of applications, the plurality of virtual environments providing a first level of virtualization within a second level of virtualization;
• monitor behavior of each application from the plurality of applications to detect unauthorized activity;
• and
• discard a virtual environment from the plurality of virtual environments without discarding the remaining virtual environments from the plurality of virtual environments when unauthorized activity of an application within the virtual environment is detected and unauthorized activity of applications within the remaining virtual environments from the plurality of virtual environments is not detected.

A method, comprising:

• initiating a first virtual environment within which to execute a first application, the first virtual environment isolating the first application from a second application executing within a second virtual environment, the first virtual environment and the second virtual environment providing a first level of virtualization within a second level of virtualization;
• monitoring behavior of the first application within the first virtual environment;
• and
• detecting, based on the monitoring, an unauthorized activity of the first application, the unauthorized activity including at least one of an unauthorized change to a non-modifiable section of the first virtual environment, a registry write, a start of a new process, corruption to an existing process, a web site visited, a redirected Uniform Resource Locator (URL), an infection detail, an event timeline, a network connection, a file system write, or a configuration change.
