Please add an overall score in the list of applications that indicates the security level of my computer.
Here the number of unsafe applications but also the threat level should be considered.
Display the score at top of the Applications list.
This should not just be a number, maybe you show a filled threat meter.
Maybe other users have better idea how this could look like.
So any suggestions are welcomed.
Provide security score, it motivates user to get the security fixes installed

If you allow multiple computers then you should show the Overall Score at each computer in the list of applications.
