It is completely clear that Microsoft has not the knowledge to write fast and efficient antimalware software. Windows Defender scans every executable file (EXE, DLL) when your application ONLY opens the file without reading or writing one single byte from it, which results in delaying CreateFile() for up to 25 seconds! Windows Defender scans each EXE and DLL file every time anew when you start an application - ALTHOUGH it has already scanned all these files when the application has been installed! So each time you start an application you have a tremendous delay: the more DLL files your application loads, the slower.Įspecially when your application uses anti-piracy protection like Themida or WinLicense, Windows Defender needs EXTREMELY long to check these files. So just checking if the service is running is not enough. Note that MsMpEng.exe is even running after turning WindowsDefender completely off in the control panel. It blocks an EXE or DLL file that my installer writes to disk for up to 25 seconds! (The installer is hanging, obviously.) On my computer it runs with 50% CPU (one CPU core fully occupied) while observing an installation. You can check for the processor load that MsMpEng.exe (Antimalware Service Executable) is currently producing.
