Safari downloading files illegally

I tried to open the following site using Safari v 5.1.5 whilst running

Mac OS X 10.7.3. The site:

www.cliftonchilliclub.co.uk/

opened apparently normally, but immediately downloaded 5 files to my

desktop without asking or receiving permission. The 5 files are named:

snippet-1.cgi, snippet-2.cgi. snippet-3.cgi, snippet-4.cgi,

snippet-5.cgi.

Apparently these are portions of the web site that Safari can't open for

some reason. Firefox, Opera and Camino all open the site but show

errors when displaying the site on the page itself.

In this day and age, and with fears of virus all over the web, isn't

this bad practice on the part of the writers of Safari to allow this to

happen?

Can Safari be set up to stop this from happening again.

I haven't opened these xxxxxxxx.cgi files. But I understand they are just

error messages, however this strikes me as dangerous behaviour.
