actually, SpySubtract marks some of the limewire files / registry settings as either spyware or adware, specifically these files/registry settings (as indicated on my computer, which is Windows XP, Service Pack 1

FILES
C:\program files\limewire\limewire20.dll

REGISTRY

all are in HKLM\Software

(Limewire)
HKLM\Software\Limewire

(Sharman Networks Ltd)
HKLM\Software\magnet
HKLM\Software\classes\magnet
HKLM\Software\classes\magnet\shell\open\command

(Grokster)
HKLM\Software\classes\magnet\url protocol

Personally, I think SpySubtract is being over cautious - remove any of these files/registry settings and limewirse either fails to work properly (eg Bitzi look up fails to work). Remove the file limewire20.dll and Limewire refuses to start up.

I've added these to the "whitelist" which means they are ignored during a scan. Other programs such as adaware, Spybot S&D and microsoft anti-spyware don't show any problems. One of the files ocassionally gets caught by panda software.

I guess the manufacturers of these different products are divided about what these actually are. I certainly don't see any of the above as spyware.
