I suppose that's within the realm of possibility, although I think unlikely. However, Panda online scan also IDs tracking/spyware cookies, and you say it was clean.

I've not used Spyware Detector, but according to their site:

This software is also powered by some advanced features that are similar to our corporate edition like, Block Active X, Block Cookies, Block BHOs, Registry back up, Live Monitoring for IE home page hijacking, system and win ini file change monitor, monitor registry changes, tracking cookies monitoring and Process monitoring. The software has a complete database of the most commonly and largely found spywares, which are detected and can be deleted immediately. Our live update module will enable our users to update their spyware database frequently.

Even though you've uninstalled it, it's possible changes to your system are still in effect.

Another thing to know about Spyware Detector was that it has in the past been listed on Eric Howes' Rogueware site. It has since been delisted, with this notation:

Note on Spyware Detector: Spyware Detector was listed on this page because of concerns with false positives. Testing with the latest version of Spyware Detector indicates that the problems with earlier versions have been satisfactorily resolved. Thus, we can no longer consider Spyware Detector to be "rogue/suspect" anti-spyware

Let me know what Lavasoft tells you, as I'm curious.
