When it comes to security software less features is better. More features => more complex => more bugs and security issues...

If you like it, keep it. For me currently MSE is the thing to install, since AVG annoyed me too much. If you just disable that feature, look for a software that does the same and does not have such a feature... especially sound in a application just for the sake of voiceovers... that's quite a lot overhead for a useless feature.
