Security question curl & port 80/macinstallerinfo

[basilt]

hello, my firewall poped a message about CURL command asking to
communicate with info. and events.macinstallerinfo.com on port 80.

I was wondering what this site is, does not exist on web and not sure if it is generated by OSX.

Any help would be appreciated on how to remove this 'macinstallerinfo' and where that file is located,
so i can block it or better remove it !

I opened my HOSTS file with Gas mask and did not see any entries in there at all.

Thanks
