One of Vista’s big security features is the Windows Defender anti-spyware utility. However, you can also get it if you are (wisely) staying with Windows XP. This is a pretty hefty service, though, taking up about 16 MB of memory on my computer.

If you are worried about spyware, this is a great addition. If you are like me, and don’t have much of a spyware problem due to using Firefox, stick with running Ad-Aware or SpyBot once in a while.
