Today, for the first time in over two years of using first NIS, then two newer versions of NS, I came back to my computer after waking it from sleep after an hour or, so to a Application Compatibility Check alert (see norton compat.pdf) for Trusteer Rapport Endpoint Protection. NS and Trusteer have been working all this time with no alerts like this. I see there are a few threads on Trusteer but there doesn't seem to have been a single solution.
If I click Skip & Continue I get a dialogue as though I'm installing something called Norton Community Watch (see ns.pdf attached). When I click ed through it installed a few version of NS with a slightly different interface.
