OK, I'm wondering if this has been caused by the Defense+ Clean PC Mode..
Clean PC Mode: From the time you set the slider to 'Clean PC Mode', Defense+ learns the activities of the applications currently installed on the computer while all new executables introduced to the system are monitored and controlled. This patent-pending mode of operation is the recommended option on a new computer or one that the user knows to be clean of malware and other threats. From this point onwards Defense+ alerts the user whenever a new, unrecognized application is being installed. In this mode, the files in 'My Pending Files' are excluded from being considered as clean and are monitored and controlled.source
.. and what CIS update might have done to the My Pending Files
list and your Safe File
list. Previously were you controlling the My Pending Files
list (moving known files to the Safe File list)? What was Safe List called do you remember? I beginning to suspect that the CIS update might have wiped this safe list and that is what is causing all the alerts.
In the mean time, I recommend switching Defense+ to Safe Mode
to limit the amount of alerts and based on what you said previously.. you might want to switch the Firewall to Custom Policy
mode to stop applications accessing the Internet without your specific authorisation.
