uninstall the package by executing:
/etc/rc.d/init.d/squid stop ; rpm -e squid
If you want to continue using the Squid proxy server software, make the
following actions to tighten security access to the manager interface:
mkdir /home/httpd/protected-cgi-bin
mv /home/httpd/cgi-bin/cachemgr.cgi /home/httpd/protected-cgi-bin/
And add the following directives to /etc/httpd/conf/access.conf and

--- start access.conf segment ---
# Protected cgi-bin directory for programs that
# should not have public access
order deny,allow
deny from all
allow from localhost
#allow from .your_domain.com
AllowOverride None
