Just wondering if anyone else has seen this issue. I'm currently using the latest ESS 6.0.308 x64 version, and I've been noticing an annoying but not fatal issue where the Windows 8 Action center would randomly but regularly toggle a popup message in the taskbar about not having an firewall or antivirus installed. If I open and stare at the action center, I see that it briefly toggles between the normal state (where it is installed and working fine) and not having anything installed. I have done a full clean / reinstall of ESS 6. I didn't see this issue with the latest ESS 5 installed. Any ideas on how to get rid of this, as annoyingly harmless as it is?
