ABSTRACT:
In one embodiment, a protected process is monitored by one or more watchdog processes. Upon detection that the protected process has been abnormally terminated, the watchdog processes may initiate actions to identify and/or terminate one or more malicious processes terminating the protected process. For example, the watchdog processes may inject a detector in processes running in the computer. The detector may listen for an activity that would terminate the protected process, and report such activity to the watchdog processes. The watchdog processes may be configured to terminate malicious processes identified as abnormally terminating the protected process. Thereafter, the watchdog processes may restart the protected process.
