The Chrome autoinstall changed my registry settings so that things broke when I uninstalled Chrome.
I’ve found in the past that Chrome’s autoupdate takes over my CPU at random times (seen as ‘setup.exe’) so I uninstalled it then. However, after uninstalling the version installed with Avast, clicking links in emails and on some Firefox pages was broken as described at http://www.msoutlook.info/question/242 because Chrome changed some registry settings.
Please provide an option for users who don’t want to install Chrome.
