No, especially not Mars.
The best method to protect, is to when you get each item, program it's aura. Place your hand on or over the item, see yellow or gold energy around it, and affirm something like "this (whatever it is) is always safe, secure, and functioning perfectly". Only state this 10 times, probably. You can do it daily for a while if you feel the need for it.
You can try this now before it goes retrograde, over the few days when Moon is in Aquarius would be great.
