Windows Defender in XP

You can download and install Windows Defender free of charge on the Windows Defender website.

You’d uninstall Windows Defender just like any other program in Windows XP.

Windows Defender is built into Windows Vista and is activated and running by default unless another antivirus software has deactivated it or you choose not to use it during installation.

If you don’t have another antispyware software package running the Windows Security Center will nag you with a balloon warning at the bottom right of your screen. You can click that balloon and then click Turn on now next to Spyware and other malware protection to turn Windows Defender back on.
