Apps that install AppInit DLLs can't be certified. The AppInit DLLs are loaded by calling LoadLibrary() during the DLL_PROCESS_ATTACH process of User32.dll. Their early loading provides an easy way for malware to run in every process. It can also cause system deadlocks, and may decrease system reliability and performance.
