Question about Microsoft Windows Vista Home Premium with Service Pack 1: Windows
Updates for Windows Defender are usually included in
regularly scheduled Windows updates. However, you can manually download and
install the updates yourself.
Updates may be available in several places online, but only download those from Microsoft's official website.
Files from other sources may in fact be viruses or other malware disguised as legitimate update files.
Log into your Windows Vista computer as an administrator.
You will need administrator rights to install the update files.
Check whether you are running the 32- or 64-bit version of Windows Vista by clicking on the "Start" menu, then typing "system" in the search box and clicking "system" in the programs list.
For the "System type" entry you will see either "32-bit operating system" or "64-bit operating system".
Download the update definition files from Microsoft's website.
There are different versions of the files for the 32- and 64-bit versions of Windows Vista, so be sure to download the correct version for your computer by simply clicking the appropriate link (see Links below), which will start the download automatically.
Click "Run" when the download has completed to immediately begin installation.
Follow the prompts on your screen to complete the installation, and restart your computer if necessary.
A restart is not usually required immediately, but is usually required in order for installation to be fully completed, so restart as soon as possible.

The Windows Defender software constantly scans your computer for threats such as spyware that may slow down your computer or try to steal personal information.
If the software wasn't installed properly or is conflicting with other programs running on your machine, Windows Defender may not work correctly.
To repair the software you either need to download the latest update available for the program, or you need to completely uninstall and reinstall Windows Defender.
Restart your computer's operating system.
Double-click the "Windows Defender" icon in the system tray at the lower-right end of the screen.
Click the question mark icon at the top of the Windows Defender screen and choose "Check for Updates."
Select "Continue" if you are running Windows Vista.
Wait for the updates to finish installing and click "Scan."
Click "Stop Scan" if the problem persists.
Click the question mark icon again and select "Exit Windows Defender."
Click "Yes" to confirm you want to close the software.
Open the "Start" menu screen and select "Control Panel." Select "Uninstall a Program" in Windows 7 or Windows Vista, or instead choose "Add or Remove Programs" in Windows XP.
Click the "Windows Defender" entry and select "Uninstall."
Choose "Yes" and restart the computer after the program is removed.
Navigate to the Windows Defender installation webpage (see Below).
Click "Download" and double-click the Windows Defender installation file when it downloads to your hard drive.
Go through the onscreen installation instructions.
Open the "Start" menu and choose "All Programs."
