F-Secure anti-virus says your computer is not protected
I am using F-Secure anti virus for work stations but it hasn't been working for a few days now. on the interface windows it says: "Your computer is not protected. Malfunction. Please restart your computer".
I have restarted it but it is still not working. When I go to Downloads i can see that F-Secure Aquarius Update 2015 and F-Secure Hydra Update 2015 are not installed but I don't know how to install it.
Can anyone help me?
