Sorry I just realized what you meant by the name....yes you only see whatever proper name you entered in your profile. Others only see your user name or whatever name you've chosen to display..
My goodness, you must have restored back several years !! That's no mean feat! Make sure McAfee is up to date and more importantly make sure that Windows is totally up to date. I assume Vista is SP1? Also make sure, even if you never use it, that Internet Explorer is IE9.
Check Windows Update settings that it's set to fetch updates for all products via Microsoft Update, that also helps although some optional updates may not be necessary. (Mine keeps offering me an older graphics driver than the one I'm using).
