I'm not using viewer2, so I don't know if the newest version has this setting but I've read that you can chose options.

Me >> preferences >> setup >> disable automatic updates

You can download any previous V2 version from http://wiki.secondlife.com/wiki/Category:Release_Notes.  I strongly suggest that you manually delete the current version before installing the replacement, instead of installing the new one on top of it.  Then, before you log in, type CTRL + P at the login screen to open your Preferences. Then go to setup >> disable automatic updates so that it doesn't automatically update itself again.
