When you run the rating scan again does the same untrusted root certificate show up? When I tried it worked.

Yes, every time the same certificate.

What is your setting for Do not automatically clean up suspicious certificates?

Checked.

I just created new user account.
Sorry for inconvenience.

A new user account in Windows? Did that solve the problem?

Yes, new user account in Windows. There is no that certificate in the new user account.

Should be fixed please check with Comodo Internet Security v10.1.0.6460 - BETA

Yes, it really fixed! It works.
