I e-mailed Earthlink and got the following reply at 12-21pm:

Pity some UK companies and organisations seem unable to respond as quickly.
Nothing to worry about. Definitely no need to subscribe to Earthlink or get the pro version of ZoneAlarm just for that.
I think the Alexa thingy comes bundled with more recent versions of IE itself. To do with the "Related" option in the toolbar and maybe other things. Nothing serious. Spybot detects it too. You can keep or remove it.
The other stuff is just "tracking cookies". Cookies almost always "track" your surfing to some extent. Different spyware detectors may have different classification as to whether a site's cookie is spyware or not. For example, one of yours listed is passport.com which is Microsoft's network (probably to do with hotmail, Messenger etc).
Cleaning up your cookies from time to time will sort it out.
