How to run Defender in Windows Vista

The best way to get Defender working correctly

QUESTION When I try to run Defender in Windows Vista I get a message that it's turned off. I select 'Turn on and open Windows Defender', but then get the message 'Error Ox8000106b5'. Help and Support tells me to select Tools and click on Options, but there is no such choice in the drop-down menu. Please help me solve this problem. Alan St. Pierre

HELPROOM ANSWER Your best bet is to install the free Microsoft Security Essentials suite. This includes a newer and more powerful version of Windows Defender. Get Security Essentials from:

Download Microsoft Security Essentials 2.0 [for 32-bit Windows computers]

or

Download Microsoft Security Essentials 2.0 [for 64-bit Windows computers]

or

Download Microsoft Security Essentials 2.0 for Windows XP [32-bit]

As part of the installation, Security Center will disable Windows Defender, preventing it from running again and removing the messages.
