You can revert to version 22 and stop the update to version 24 by turning off automatic live updates and never clicking on live update. You must then manually download the virus definition updates as often as you want them to be updated as explained here:
I have done this, but I am already tired of having to manually download and install the definition updates. I don’t think I will continue doing this for very long. I am waiting to see if they fix the most important problems with version 24. If that isn’t done by the end of January, I 'm going to leave behind Norton after more than 20 years of being a customer. This whole update has been a fiasco.
