You have to actually accept the warning dialog that pops up to get all that crap installed. This is assuming you've got the IE security setting for Internet set to medium or high as the prompt for signed activeX controls only appears by default for those levels. Read the page at
SpywareInfo.
It didn't do anything to me when I went to the page but then I've turned off most of the crap in IE6 and have ZoneAlarm to disable popups. Oddly whenever I've freshly installed Windows and IE, the security settings for the zones in IE are all set to custom. I turn them all to medium apart from restricted sites which I set to high and it works fine for all the sites I use.
I also turn off sound and music in webpages because I've yet to find a page which had it that wasn't instantly annoying as hell. Can't disable the Flash animations that have sound though like that IBM advert from a while back.
