Why is this happening in zsh?

[Anonymous <remailer@xxxxxxxxxxxxxxxxxxx>]

I am moving away from Bash to zsh and I have one problem that keeps coming
up. Somehow zsh is interfering in interpreting commands and I know there
must be an option to stop this but I can't figure which one to use. An
example is

fossil --ignore *.class
zsh: no matches found *.class

fossil never receives the command at all

I also have problems sometimes with rsync and have to use Bash. zsh is
trying to substitute things that are supposed to be passed to the
command. How can I set zsh to always ignore these without breaking something
I haven't though of maybe like rm *.class
