Although recommended by UFC Que Choisir, I find it difficult to use software when it comes to change the protection settings. It is not known what level of protection, so we do not know how to change it. A website with interactive applets are inaccessible while with Norton I had no problem. By email with request for a Canon software that did not want to open properly (for another reason besides): perfectly generic response ie uninstall-reinstall. The software is probably good but after UFC user interface is not friendly at all. Finally, and this is unfortunately a widespread custom in France, I find it outrageous that when a customer wants to contact the supplier by phone, it is he who pays communication!
