Relevant Knowledge is spyware on your computer that reports to marketing companies for targeted advertising. I had this removed with Super Ad Blocker (free) but it apparently found it's way back on to my computer. Either that, or it never was completely removed. It is dangerous only in the sense that it builds up spyware on your computer.

I have removed it from my system 2K and have not had any problems.

It is spyware/adware. Go to Comscore.com and look at their list of clients, and you'll know how it managed to attach itself to your PC - AOL, MSN, Pepsi, Nestle's, just a whole bunch of big-name corporations are clients of theirs. It took me forever to find out that MarketScore and RelevantKnowledge are actually Comscore.
