Using cpanel on my hosting account, I created a subdomain - e.g. www.clothing.mysite.com
A cgi-bin folder was automatically created in the directory for clothing.mysite.c
You can safely delete "cgi-bin" folder, it's hardly ever used nowadays
Also beware that when your server got some malware scripts scans different folders and then hides on folders like cgi-bin because they rarely are checked now.
I even wrote a script before that "monitors" different folders in my server and alerts me if it found different scripts in there on my personal and clients servers too.
