explorer.exe access memory cis.exe alert

Hello good people, this is a popular alert on a vista system that is usually at the top of the alert list upon a fresh start up. Could this denial of access cause performance issues for this particular system? should a rule be created to allow? or should this be left alone?

I do not see any performance issues as it tries only once on each start, with some programs that have repeated tries this could be a problem.


Thanks Dennis2.
