Removing the Cerber Security Plugin Data from your Child Site

Security plugins on your child site can help find security issues and help block specific users, but one thing to be aware of is security plugins which end up causing serious performance issues. One such security plugin is Cerber Security, which has been known to cause performance issues on sites.

Ceber Security plugin will end up making a number of request to plugin files, as well as causing high CPU usage, due to the amount of PHP resources that it ends up using.

When deactivated and uninstalled, the plugin will still leave behind a number of options and database tables. The option values that it will leave behind are as follows;

_cerber_db_errors
_cerber_up
cerber-antibot
cerber-antispam
cerber-groove
cerber-groove-x
cerber-hardening
cerber-main
cerber-nexus_master
cerber-nexus-slave
cerber-notifications
cerber-policies
cerber-recaptcha
cerber-scanner
cerber-schedule
cerber-traffic
Cerber-users

In phpMyAdmin you can search by option names _cerber% and ceber% then you can delete all of the created option names.

The database tables to delete (drop) also in phpMyAdmin are as follows;

cerber_acl
cerber_blocks
cerber_countries
/cerber_lab
cerber_lab_ip
Cerber_lab_net
cerber_log
cerber_qmem
cerber_traffic
wp_cerber_files
wp_cerber_sets

There are a number of security plugins which can be used in place of Cerber Security, but always be aware that any plugins being used on your child sites can cause knock on issues when it comes to causing performance issues and using CPU resources.
