It depends. if you installed the debian package - I would use the package manager (software center, etc.) to uninstall it. Alternatively you can do it from the command line:
#apt-cache search aducm
aducm360-ide-linux-gtk - ADuCM360 customized Eclipse IDE for C/C+ + Developers
#sudo apt-get remove aducm360-ide-linux-gtk
or
# dpkg --remove aducm360-ide-linux-gtk
If you use the tarball. Go into the installed folder and execute teh remove.sh script.
