explorer.exe is in blocked applications list

although explorer.exe is in blocked applications list, it is a trusted file, and it seems to be functioning properly.
I think it got on the blocked applications list when I chose to block a certain installer.

Should I leave it on the blocked applications list, or click on “unblock”?

explorer will always be added to the blocked applications list whenever you get a HIP alert asking for explorer to execute any unrecognized application.
