Windows Defender is a software program that Microsoft has developed to make Internet browsing safe for Windows XP and Windows Vista users. The software helps in preventing, detecting, and removing spyware and other troublesome and harmful programs from your computer.
Windows Defender helps you protect your computer against undesirable pop-up ads displayed by adware programs, slow system performance due to unwanted spyware programs running in the background, and other security threats caused by spyware and adware infections. The tool works by scanning your entire computer for spyware information and then completely eliminating it from the system. The tool provides Real-Time protection for your computer and prevents spyware from infiltrating and installing itself on your system. With each alert, the tool gives relevant information about the detected threat and helps you make the removal decisions. In brief, the Windows Defender tool has been designed to keep your system secure and free from malicious spyware and adware programs.
To ensure that your computer stays secure against the latest spyware, Microsoft releases regular Windows Defender updates. These updates are installed when Windows Update is run on your system. You may encounter the following error message while Windows Defender is being updated on your Windows Vista computer.

Method 3: Ensure that there are no problems with Microsoft Windows Update, Automatic Updates and Windows Server Update Service (WSUS)
