I have Comcast which comes with Norton; it's part of the monthly charge we pay Comcast I guess.
I set my computer to an earlier time recently to try and deal with what seemed like bad virus problems that Norton couldn't seem to fix. The date I set my computer to, by the way, was just about two weeks ago. This seemed to cause problems with my Norton Security Suite.
I was prompted to install Norton's UPDATES but it couldn't install "all" updates. I had an error message that stated I had no IP address. I must have had or I wouldn't have been online and I was online. When I tried to do a "Quick Scan" on Norton it wouldn't let me. I tried repeatedly with the same result. This seemed to be due to the fact that Norton couldn't install all updates. Every time I tried to do a Quick Scan the screen superimposed another Norton screen about installing the updates and "one click settings" . I tried this a dozen times with the same result.
I called Comcast, which assigns you different IP addresses routinely since Norton error message stated I had no IP address and was told by the Comcast rep that I should contact Norton and I was given a Norton Help telephone number. I called Norton but when I heard their recorded message stating that all assistance was "chargeable" I hung up. Why should I pay for help with what seemed to be a problem on their system?
