Some of us didn't get the choice. I can assure you that the install dialog box that you showed us earlier NEVER appeared when i upgraded (I use Win7). Even if it had, it is very plainly worded in a misleading way, so that it appears that you have to accept the toolbar to upgrade (normally, when you hit the "No Thanks" button, it aborts the install, you have stated that it bypasses the malware and continues the install, which I tend not to believe).
