It suggests modifying le registre to désactiver the Logitech télécharger assistant.
Under the clé HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run there devrait être an entry called Logitech Download Assistant.
Supprimer this and it should fix your problème, vous allez have to do this for every ordinateur you use the souris avec.
Vous pouvez be able to désactiver it using the startup tab in task manager à la place of using regedit but J'ai no way to test this though.
