is there any standard procedure to uninstall software packages which have the above extensions??

i know how to uninstall through yum or apt-get.. but how to tackle these files??

like Nvidia drivers comes in .run
adobeAIR comes in .bin
netbeans in .sh

And what if i have installed from source i.e tar balls?? are there some protocols to follow??

i think it may sound a lame question but i was wondering about this since days coz i want to remove some of the apps from my laptop.. please help..

There is no standard way to remove packages like that, you have to hope the installer has an uninstall function, or else do it manually. As for source installs, some might have a "make uninstall" target, but it is totally optional on the part of the developer.

Situations like these are why package managers were developed. You should always try to find a a proper package for your distro rather than using an installer script. Never install a source tarball directly to the system, you should instead build it into a binary package for your distro and install that.

I don't know about the others, but for the NVidia driver run:
