Issue: "when not logged in on any google accounts .. I can visit http://www.youtube.com but when I try to login, in which case it redirects to https:// and It shows the following error(check image url):

And if I try to add exception, it shows this screen(check image url):

Troubleshooting: 
delete cert8.db
tried to add exceptions
deleted cookies
clicked "I understand the risks"

Results: 
why you get a completely different certificate when you visit the site compared with the one I get (*.googlevideo.com vs. www.google.com). Considering that you get Google's 404 error on the URL that should serve the YouTube home page only after you log in, I am suspicious that this could indicate foul play.

Invalid, the host file had a redirect for youtube.
