Windows Defender question

[twl845]

I just finished setting up my Sons new computer with Vista Premium included. As you know it comes with Windows Defender. I am unfamiliar with Defenders performance, so can you folks clue my in as to whether it does a decent job? I am using XP on my pc, with my own arsenal, so I have no experience with Defender. Thanks;D

Widows Defender is not very good at detection.
I would supplement it with a good scanner.Not sure which ones are Vista compatable yet.
