I’m bringing this thread back to ‘top’ just to mention a silly test that shows Microsoft seeking harder and deeper for spywares.
For the always-blamming-against-Microsoft-users: http://www.flexbeta.net/main/articles.php?action=show&id=84&perpage=1&pagenum=3 (comparison of MS AntiSpyware vs Ad-Aware vs SpyBot).

For the ones that expect it free after the beta period, well, bad news :cry:
