IBG in 2005

Back again after a brief interlude. When BT's servers went down a few weeks ago and their Indian call centre thought it was at my end, I messed about a lot. I switched off my PCcillin to reinstall my broadband and forgot to put it back on. CoolWeb killed me yesterday so had to reinstall. Reinstalled my security first and Ad-Aware scanned automatically. Gave 8 Alexa trackers before I started normal surfing. Will they use these to calculate traffic figures as well as the Alexa Toolbar?
