I'm not a fan of toolbars and never had any installed but read that the Google toolbar will stop the "pop unders" so i installed it to try. But, when I access the Dell Community and users forum, Home - Dell Community
it's OK when I first access but if I want to display one of the problem posts and do a "right click" to open in new Tab, with the Google toolbar installed I get the "404" page not found error. From there it deteriorates to 404 for any Community page. Dell support Welcome to Dell Support
I disabled the Google Toolbar and I still had the 404 on the Dell Community so I uninstalled it but had to reboot and after the reboot and Windows 7 startup I could again access the Dell Community and also right click to select "open in new Tab" to look at a problem post.
I then decided to try it again but went through the same problems and process to remove it. No more trying the Google Toolbar, at least with my configuration. Other sites, that I accessed, were OK just Dell Community.
I have Win 7 64 bit Prof and I.E.8
