Today, I ran Spybot on this computer (used mainly to read email); it found tracking cookies from 10 companies on this PC "protected realtime by Microsoft AntiSpyware":
Advertising.com; Avenue A, Inc.; BFast; CoreMetrics; DoubleClick; FastClick; HitBox; MediaPlex; ValueClick; and WebTrends Live.I have a hard time believing that Microsoft is serious about spyware prevention, give this miserable experience. Granted, this wasn't written in-house; they acquired a company called "GIANT" (the process name is gcasServ - Giant Company Anti Spyware). You may recognize several of the cookies detected -- they're from infamous/notorious spyware purveyors that the whole world - including Microsoft - knows about. Then again, maybe Microsoft is defining "spyware" differently than the rest of the world ... or perhaps Bill Clinton (who doesn't understand the meaning of the word "is") -- is consulting for them.
