I have Comcast for my Internet service. The version number that I have now is 21.3.0.12. I just read the announcement for a new version of Norton that is 21.5.0.19. Does this new version apply to Comcast Internet users? The update is supposed to come in the form a LIve Up Date correct. Can I get the update through Check Updates that is located on one of the responses if it does not apply to Comcast users? Do you have any information on how long it may take for the update to be available. Any information is always well appreciated.
