Tribalfusion IS NOT spyware.
Banner ad's ARE NOT spyware.
Cookies ARE NOT spyware.
Tribal Fusion is nothing but an Internet banner placement service Flyertalk uses to show relevant banners, the "spyware" is nothing but an innocent cookie Tribal Fusion uses to monitor the ad's it has served you, making sure you don't get 1000 public service announcement banners and zero commercial banners.
I wish these "spyware" scanners would once and for all stop claiming that cookies are evil. TRUE spyware is nasty stuff, impossible to remove without decent knowledge and not made for innocent purposes.
