You mean "Spybot" rather than sky-bot, I think?
Last time I looked, the rootkit scanner was a beta. Shouldn't really be used, unless you know what you're doing, if that's the case.
ADS processes found using a rootkit scanner are not necessarily rootkits. When they're flagged, it means it might be suspicious, or it might not.
In this case, it would appear to be part of the process of Norton - which I presume is your antivirus - and probably harmless. And if Norton is not your antivirus, I strongly recommend you remove it.
That said, I'd install, update, and run a scan with MBAM, for a second opinion. It's a very good scanner. There is a free version.
