I am running Windows 7 Home Premium on my emachine laptop and have enabled Microsoft Security Essentials as my anti-virus programme.

All okay but I noticed Windows Defender is turned off but when I try and start Defender the programme won't open up and just hangs there.

My question is Microsoft Security Essentials also a spyware programme and doesn't need Defender turned on?

Hello PossumNZ,

Microsoft Security Essentials (MSE) "disables" Windows Defender by default. Should you ever uninstall MSE, Windows will enable Defender once again.

MSE does have malware fighting capability; however, my recommendation would be to install and run
Malwarebytes free version as an on-demand malware scanner. MSE and Malwarebytes should give your computer adequate protection.

Also, see this link: http://answers.microsoft.com/en-us/protect/forum/protect_start/windows-defender-and-microsoft-security-essentials/5309cb8d-02e1-40e8-974f-0dcedb9ab9fd

Hi PossumNZ -
As explained by Artrooks, MSE includes an anti-spyware component that's based on "Defender technology."
Here is a quick statement from Microsoft on the modern version of Windows Defender -

QUOTE - From Pa Bear (M/soft MVP)
As such, installing MSE disables Defender by default (on purpose):

If you don't like this, you can always uninstall MSE & install something else...but be forewarned that just about all modern AV apps (e.g., Norton, McAfee, Avast, AntiVir, AVG) also include an anti-spyware component and will / may also disable Windows Defender by default..
Defender can, in some cases, be re-enabled, but the technology in other modern Antivirus programs may now disable it to prevent dual A/virus programs from running
END QUOTE - The link, provided by Microsoft, also explains Antivirus settings included with Windows8

I hope this fully explains the new technology involved in many Antivirus settings -

Regards -
EDIT to check link -

Microsoft also offers Windows Defender Offline if needed for malware infection.
