To uninstall xvt just follow these instructions.
sudo apt-get remove xvt
This will remove just the xvt package itself.
sudo apt-get remove --auto-remove xvt
This will remove the xvt package and any other dependant packages which are no longer needed.
If you also want to delete your local/config files for xvt then this will work.
sudo apt-get purge xvt
Or similarly, like this xvt
sudo apt-get purge --auto-remove xvt

|Description||X terminal-emulator similar to xterm, but smaller compatible with xterm while using much less swap space. It is mainly intended for use at sites which use large numbers of X terminals but may also be useful on single workstations that are short of memory. The main way that xvt achieves its small size is by avoiding the use of the X toolkit.|
