Security alarms : new !

[PivertMe]

Hello to all,

since several days, and without having consciously modified my system settings ( execpt one HD suddenly died, and had to recover all)
I get security alarms :

- each time I click on an executable I am asked to confirm, and checkbox 'always ask for permission' is checked
( that wasn't teh case before)

- when I install programs be they form the net or from CD, I get alarm messages ( see scren captures), and setup is closed.
I have had problems installing drivers, possibly because of that I assume.

- sometimes when trying to delete / rename folders I get a message that I am not allowed to do it ( no right). That is new as well, since I am th e only user, have administrative rights. These alarms do not come form my antivirus ( Kasperky Internet Security fully upto date program and databases)

What can I do ?

TIA

PS KIS and Comodo do not find viruses. Have temporarily deactivated Windows Defender: no change

Right click a faulty folder and check if you have permissions as appropriate.
