SweetIM/SweetPacks is a malicious BHO that is commonly bundled with downloads from CNET's download.com. Even if you explicitly uncheck sweetpacks and deny it, it will install anyway. I think this classifies as spyware/malware.
It does not include an uninstaller and mockingly tells the user to manually uninstall the crapware if you try: hxxp://toolbar.sweetpacks.com/uninstall/
