[QUOTE="436880927, post: 828047"] No, that will not stop them. Most AVs which are injecting code are doing it before the process creation operation has been completed and once they are running under the context of the process who's main thread is yet to be resumed... use APC to hijack the main thread when it is resumed (alerted and then the pending APCs are fired). You can use file-less stubs and no DLL at all, a file-less stub to behave as a loader for the DLL or just use the address of LdrLoadDll. Either way, MemProtect cannot really stop people who are also running at the same privilege level as it... which I have already mentioned. You can do things manually with a CPL of 0 and MemProtect won't be any the wiser. Google can use protected process mechanisms and it still will not stop the main vendors. ROFLAO. [/QUOTE]
