Removing installed application

Removing an application which was installed using RPM is easy. But how does one remove a tar-red application installed using the 'install' command? For example, Carlos E.R. talked about the antivir program which checks for viruses so, like a good soldier, I went and got it and installed it to try it out. Now I want to remove it. To remove it, is it a matter of looking inside the archive and compiling a list of all the directories where it installed itself and then deleting those entries manually, or is there a faster method?
