Downloads blocked by "security zone"? HELP!

[Snatch]

I got a new GPS and Im trying to DL topo maps from a site, but my computer won't allow them due to security zone settings?  I have changed almost everything and it still wont allow it...

Im using firefox and Windows Live Onecare system that came with Qwest..

Anyone have the gem of knowledge that will make my day?

i believe windows liveonecare is not allowing you to download .exe files.

I've never worked with live onecare except to uninstall it because it causes issues.
