Now 4 times in a few weeks  Live Mail can not be startet. After a repair my maps has disappeared but is restored  in random order. Some of them are empty, others  can be read. All mails on the server are then reinstalled . I have scanned my PC by Norton 360 and now virus etc are found.

What can I do?  Delete the program and reinstall? What will happen to my mail's?

Please help.
