When you uninstalled did you use this method?
reboot then run
This white rectangle is it when you 1st open mcafee? If so that is a beta program effect ie you must have a beta browser do you. IE appears not to be beta so it could be a corrupt install. Can you if necessary take a capture of the screen showing it.?
When I go to the add or remove programs in my control panel, for McAfee it has a button that is "Uninstall/Change". When I click on that, it opens the program/white rectangle again, and does not uninstall the program. How do I fix that?
Please click on the first link posted above and click on the link on step no 2 (a)
Restart the computer.
Run the McAfee preinstall tool from here
Login to your McAfee account page : http://us.mcafee.com/root/login.asp and redownload your McAfee software .
Kindly let us know the status of your security center post the reinstallation
It said that I have had an incomplete uninstallation, so I am contacting tech support with the logs. I will let you know when that is fixed.
Thank you so much for your time,
The Tech support uninstalled McAfee using their program, then I restarted my computer, used the preinstall and download, but I am still getting the rectangle. Any more ideas? If I don't get something that works here, I will go back to the chat tech support, but I know they are busy and I'd like to try to fix it here first.
What is the operating system installed on your computer?
Please run Windows update and install internet explorer 9, if Windows Vista/ 7 installed on the computer and let me know the result.
As I asked can you provide a pic please
