I’m new to all this and don’t understand much of the tech stuff – but have just been hit by this Google Update problem. Am running OSX 10.6.8 and can find Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources but the contents there are:
ksdiagnostics, Google Software Update.app, com.google.keystone.daemon4.plist, com.google.keystone.daemon.plist, com.google.keystone.agent.plist and CheckForUpdatesNow.command

These were last modified in May 2012. Should I delete any of these or use one of the above scripts?
