Some of the things I look for when I suspect spy ware and it isn't straight
forward about its presence are network connections. Apart from how Windows
is by nature the noisiest Operating System on earth on a network, you can
use a connection monitor either at the host or over the wire to look for
connections made to odd addresses that weren't initiated knowingly. Try
pointing the browser at a location void of banner ads and see if any "other"
connections are made to spy ware reporting engines as browser add-ins are
the most common spy ware.
Sounds like one of us with spare time should go on a warez and pr0n site
clicking spree with another clean computer doing some ethereal watching.
Maybe there can be some Snort signatures written for the whole world to
benefit.

My advise based on some experience with bots/adware:
- Look at the running processes and identify unusual entries
- Similarly, take a look at all the run keys in the registry (autostart
for malware)
- Look for suspicious files in C:\, C:\%windir%, C:\%windir%\system32
With this information, you can find the most obvious ones. With more
stealth malware (hiding with the help of rootkits), you can look for
suspicious drivers, but a good installation will hide itself so that it
can't be detected from the command line.
>From a network point of view, look for suspicious connections at the
gateway (netflow helps here). Identify unusual flows, use of unusual
ports used for Command & Control, recurring patterns, ... Perhaps you
can also use ngrep to search for suspicious network communication.
Just my 0.02 cent,
