Piwik JS triggers qttask.exe in IE6 and pers. Firewall Alert

Hi folks,
since putting in Piwik JS in one of our website I’ve noticed that it actually triggers the QuickTime PlugIn(QuickTime\qttask.exe) in IE6 which in return brings up my firewall alert box!
I guess it comes from Visitors->Settings->Plugins, so is there a way to disable this for a particular PlugIn? We don’t wanna get any complaints from any of our visitors — and yes we still get a lot of IE6 visitors.

Cheers
