Scorecard Research is not malicious: it is simply a set of online statistics and survey tools.

If you do suspect something awry, as others have mentioned, Special:Contact is the place to go. However, Norton simply indicating svchost is using a lot of memory is not really an indication of malware on Wikia (particular if seeing Scorecard Research is what lead you to this thought).
