Windows Defender

Replaces: Ad-Aware

Alternatives: N/A

Pros: Unobtrusive, Lightweight, Fast

What’s that? A product by Microsoft that isn’t a piece of crap? And it’s free to anyone with Windows XP or Vista?! It’s hard to believe, but it’s true, Windows Defender is actually a solid product, and free so long as you’re using XP or Vista. Also, unlike it’s alternatives, Windows Defender never bugs you unless it finds some malicious software. The one thing I will say that it has working against it though is that it uses Windows Update for maintaining its spyware list.

All you ahve to do is run it, select the file(s) you would like to defrag and in seconds that file will be fully defragmented. Of course you always have the option to defrag the whole drive.
