Geraniums dying off spots on leaves

Hi, newbie here and am desperate to help my wife save her precious Geraniums. Every year they are bought into the garage at the onset of winter and go back out in spring. This year they have produced a good show of colour again but unfortunately I think some of them have a terminal problem. Half of her stock are either dying back and/or have small yellow spots on the leaves. As you can see from the pictures some are now looking quite sad but are still flowering. I suspected a fungal problem and have sprayed them with a basic fungicide such as that use for rust and black spot but with no results. I know replacements would not cost a fortune but these are her babies. Should we be worried about their condition? Is there anything we can do rather than bin them and start again next year.
Any help or advice would be appreciated.

It could be a virus and if that is the case, the plants will have to go. Its very easy to get too attached to one's pelargoniums but it might be necessary to be brutal and chuck them on the bonfire.

Looking at the information it does look very similar to my problem Ceres, if it is thats a worry.
Verdun, I would be quite happy if you are right. I decided to photograph both sides of one of the lesser affected leaves (below) and then noticed the little black "thing" on the stem of the picture of the underside. I am going to try an insecticide first and keep the affected plants separate from the others and see what happens. They have been cut back and tidied up to day and are normally dead headed on a regular basis. Looks like keeping an eye on them and if they dont improve replace the affected ones is the way to go. Thank you and Ceres for your advice.
