How to remove QEMU completely

I installed QEMU from software center but removed latter (using software center). But updates are recommended to QEMU (see screen shot). That means QEMU is not uninstalled properly. How can I completely remove QEMU from my computer?

enter image description here


Using the Terminal

Uninstall just qemu with

sudo apt-get remove qemu

Uninstall qemu and it's dependencies with this

sudo apt-get remove --auto-remove qemu

If you want to purge all the config and data off the system you can also use

sudo apt-get purge --auto-remove qemu
