Stopping programs for automatically....

As per the title

is there a way to stop programs from starting automatically on boot up?
I am running a beta version of a VPN software that I need for work (last reason why I needed windows). This program shows up in the menu bar after a reboot but is not listed under login items. Security policy is automatically set to ON preventing the OS from seeing any servers in the network. Is there a way to stop it from starting on boot up?

thanks, sorry is this is a newbie question, I'm new to this MAC thing.

 

thanks for your reply but as per my original message, this program is not listed under my login items.

 

I did, it's a beta version with very few options, even when I disable the "security option" it doesn't seem to save it, next time I reboot the system, the option is checked again.

Overall, I am pleased that I can now connect to work without having to use a windows machine, I refuse to run windows on the MAC.

 

I am going to do just that, we are going to have a few new mac user join our network in the next few weeks; we need a reliable version before we can move forward.

thanks for all your help
