Our company just purchased a new desktop computer running the Windows 7 Professional 64-bit operating system. I was wondering if Microsoft's Windows Defender is part of the operating system? The new computer does not have an anti-virus program installed, so I'm hesitant to obtain Internet access without some kind of protection. If Windows Defender is NOT part of the operating system, then how can it be safely installed?
PS. Our company has purchased an anti-virus program for the computer, but it will not be available for another two weeks (red tape issue). Until then, I will need Internet access to activate the Office software and get it configured for the user's needs.
