I have installed Comodo and GeekBuddy.
By default, both try to boot on Startup.
Comodo starts but GeekBuddy gets part way through booting and comes up with an error message:
"Error retrieving Font Size".
I have to OK this about 7 or 8 times before GeekBuddy resumes completion of boot up.

It also comes up once if I exit Geek Buddy.
