14.04 - How to Remove varicad2013-en (A Virus or PIA)

I am having a problem. I was running out of space and remove varicad2013-en from my system manually. Now when I try to do a system upgrade, the system fails with the following message:

Processing triggers for menu (2.1.46ubuntu1) ...
Errors were encountered while processing:
 varicad2013-en
E: Sub-process /usr/bin/dpkg returned an error code (1)

Here is another example:

sudo apt-get purge varicad2013-en

When I try to install any package, I get same message, so my machine is stuck in limbo over this package / virus.

I have tried:

dpkg --configure -a
dpkg --purge varicad2013-en
apt-get remove --force varicad2013-en
apt-get remove --force varicad2013-en

I get stuff like:

Errors were encountered while processing:
 varicad2013-en

E: Sub-process /usr/bin/dpkg returned an error code (1)

or

dpkg: error while cleaning up:
 subprocess installed post-installation script returned error exit status 2

How do I remove the package from the Ubuntu 14.04LTS?

I am thinking to wipe the entire drive.. but.. there has to be an easier answer.
