I am using Ubuntu 14.04. I have installed mcafee antivirus. But now I am unable to uninstall it.

While running command sudo dpkg --purge mfert it gives the error:

dpkg: dependency problems prevent removal of mfert: mfecma depends on mfert.
dpkg: error processing package mfert (--purge): dependency problems - not removing
Errors were encountered while processing: mfert

How can I uninstall mcafee antivirus?

press CTRl+ALt+F1 to switch to a terminal and try to remove.. using commands ..

"The following commands will cleanly uninstall and remove package-related database entries from the system database. No additional commands are needed."

sudo dpkg --purge mfecma

sudo dpkg --purge mfert

** if you still receive the error, you may use --force-all

Eg

 sudo dpkg --purge --force-all mfecma

"If the folders still exist, the following commands can be executed to remove agent-specific folders:"

sudo rm –rf /opt/McAfee/cma

sudo rm – rf /etc/cma.d

Then switch back to your desktop with CTRl+ALt+F7
