How do you remove "PriceLess"

You could try running Spybot Search&Destroy or a similar program.

If that doesn't help either you could go on a site dedicated to this kind of problem solving and ask there: http://www.bleepingcomputer.com/forums/

They can help you with the use of some more specialized diagnose/removal tools which you shouldn't usually use without special knowledge.
