I just have a little Question, if I drive a reset pin to low (reset active) of an Atmel AVR for a long time (1 week for example, in fact it'll be really variable depending on the use) can it cause default to the controller within a year or two ?

No, this should not cause a problem. The one thing you need to worry about is the electrical state of the I/O pins during reset. Determine what state all of the I/O pins go to during reset (probably to input mode, perhaps with a weak pullup) and make sure that whatever is connected to them will not be damaged or cause damage to the AVR itself. Remember that all input pins should be held at a valid logic level and not allowed to float. This may mean that you need to add pullup or pulldown resistors in places where you might not otherwise need them.
