NIS 2010 was working fine up until a few weeks ago. I have since had several instances where Windows gave me a message saying that I had 3 important messages. Among those three messages: I didn't have any firewall or virus protection. NIS seems to be working, but Windows says it isn't. Rebooting often fixes the problem, but I got tired of doing that all the time.
I tried the steps outlines in http://community.norton.com/t5/Norton-Internet-Security-Norton/Windows-7-is-not-detecting-Norton-Internet-Security-2010/td-p/238259
That didn't work.
I chatted with Norton's Tech Support. They edited the registry and that seemed to work for a while, but I once again started getting the 3 important messages.
I ran some software I bought called "Registry Mechanic" to clean out the registry. That hasn't helped.
I used the Norton Removal Tool and totally re-installed NIS 2010 several times. That works for a day or so, then I get the 3 messages again.
I have noticed that there seems to be a corelation between NIS 2010 and the printer driver software for HP Photosmart printers. Every time I removed and re-installed NIS 2010 yesterday and today, my PC doesn't recognize the printer (I tried two different HP Photosmart printers (they were two different models - 6200 series and C4795)). I have to re-install the printer drivers every time. By the way, I did download the latest HP Photosmart printer software from HP's website each time. I don't know if this corelation has anything to do with my getting the 3 important messages or not, but I have noticed that every time I remove and install NIS 2010 it loses the printer drivers.
Does anyone have any ideas?
