Cool. I agree with all you've said about Spybot Search and Destroy by the way, the author is right near the top of my genius appreciation list and I recommend his software wholeheartedly, it's precisely the sort of free software that free software should be and any compensation that's been sent his way is most appropriate. With that said my Spybot hasn't been updated in about two years and I doubt I fire it up (casually) once in ten months (or anything else like it. I'm bulletproof, baby). However, I have to mention another utility by the same author that I have installed and use almost daily:
Filealyzer
http://www.safer-networking.org/en/filealyzer
It does all sorts of great stuff related to file previews and analysis, after it's installed you just right-click any file to view it. I can't give it a full review just now but it gets my highest approval rating for useful and well behaved free programs. I use it to check file properties (even as far as checksums and and signatures), preview files (safe html viewing), see version info, see import/export dependencies (DLLs), quick hex dumps and text string searches (quickly see a model's raw files), etc.
Note: Just yesterday I was <a href=http://news.com.com/Microsoft+buys+Windows+utility+software+maker/2100-1016_3-6095376.html target=mark>reading</a> about another fellow on my genius appreciation list who also makes <a href=http://www.sysinternals.com target=free>brilliant free software</a>. It's the guy who's famous for uncovering the Sony rootkit thing - he and his company have been absorbed into Microsoft. (My favorite tool of his being
Process Explorer.)
