Abstract
A method for detecting malicious activity of a computing device comprises detecting, by a software driver executing within a kernel mode of an operating system being executed by the computing device, an operation performed at the computing device; intercepting the operation; receiving, by a security application executing within a user mode of the operating system, a request from the software driver for an instruction for the software driver for an action to block or allow the operation according to a first timeout value; generating a second timeout value based on an amount of time determined by the security application; transmitting a reply to the request that includes the second timeout value to the software driver; transmitting the instruction to the software driver in compliance with the second timeout value; and executing, by the software driver, the action in response to the instruction.
