How kfixer works

The kfixer utility patches the system memory to prevent the existing kernel extension from being unloaded (until the next reboot of the computer), and erases the kernel extension from disk. If, prior to the next reboot, you upgrade or reinstall the agent, a new, fixed, kernel extension is loaded into memory and stored on disk.

At the next reboot, the old kernel extension is unloaded from memory by the reboot process, only after all application tasks have finished. When the computer restarts, it either already has a new kernel extension, because you have upgraded or reinstalled the agent, or it cannot find any kernel extension and so downloads the new, fixed, kernel extension from the runtime server.

In either case, the agent is now running with the new kernel extension, that has been fixed so that it does not allow itself to be unloaded until is current task is complete.
