When you try and install multiple antivirus (AV) solutions on a system running the Microsoft Windows operating system, the installation of other solutions may be blocked by the installed due to the fact that a security software is already running on the system. The core reason for this seem to be incompatibilities, but performance and system stability need to be mentioned in this regard as well.
You may already know that Microsoft will ship Windows Defender with the Windows 8 operating system, which is comparable to the Microsoft Security Essentials program that is not compatible with Windows 8. At least the front of Windows Defender running on Windows 8 looks very similar to Microsoft Security Essentials on Windows 7.
