follow these steps:
(1) Press Ctrl-Alt-Del
(2) Choose Task manager
(3) From File | Run, run cmd.exe as an administrative user (check checkbox underneath edit)
(4) Note that text input is impacted by the explorer restarts. You will have to type carefully and likely will need to repeat multiple letters
(5) In the command shell, type taskkill /f /im explorer.exe (same cautions about typing apply)
(6) This should stop the flashing and make the rest of the steps easier to manage
(7) Type cd "\Program Files"
(8) Type dir /s bushell.dll
(9) In my case, the dll was found in "c:\program files\Norton Security Suite\Engine64\220.127.116.11
If bushell.dll is not found, repeat steps 7 to 9 but use "\Program Files (x86)"
(10) Type cd "c:\program files\Norton Security Suite\Engine64\18.104.22.168" (replace with the name of the directory you found the extension in)
(11) Type ren bushell.dll bushell-crash.dll
(12) Restart the system (you can do that from the command line by typing shutdown /r /f /t 0)

10.Go to the "Services" tab and select "Disable All" then click on "OK".
11.You will receive a prompt to reboot your computer. Go ahead and do so.

13.If the problem is gone then it's just a process of elimination from here. Start up your msconfig.exe again and start bringing up services a few at a time.
14.I am not sure if it will be the same for you, but if you want to try, you can turn on all services except the two that were causing the problem for me.
