Hey site admin - Alexa is spyware..
Why would you recommend a browser 'helper' such as Alexa? It's classified as spyware/adware by every major anti spyware/adware program. It collects personal data from the user and transmits it to Alexa's central database for use in targeted marketing. Worse, if the user is foolish enough to use his or her primary email address, the result will be more spam. And as a 'browser helper' it will likely slow down IE and get past any firewall since it's seen as part of IE by firewalls. Shame on you.
