ssh-agent is part of the ssh suite of programs. Basically it allows you
to have a secure connection to another machine using public/private
keys. Once you have authenticated your connection using your passphrase
via ssh-add, the session details are kept in RAM on the client machine
and you can access the server securely without needing a password.
If you have not explicitly installed ssh on your machine (IIRC it is not
installed by default) then I would look closely at the possibility your
machine has been compromised. However, depending on what applications
you have installed, ssh may have been pulled in as a dependancy.

1. Having a great deal to say
2. Not saying it
