PIE TO REPLACE COOKIES ...

(hat tip tech web)

These unscupulous badguyshave found a way to bypass antispyware programs with PIE, or persistent identification element, a technology that's uploaded to a browser and restores deleted cookies. In addition, PIE, which can't be easily removed, can also act as a cookie backup, since it contains the same information.

PIE uses a feature in FLASH to accomplish this. Macromedia has already posted instructions on how to turn off the feature.
