I really don't think you need to change shooting file format. Just follow this simple and easy rules:
1. Get your memory cards ONLY from trusted reputable sources that will honor any given warranty.
2. Always format cards IN CAMERA, not in computer. Same goes for deleting individual files.
3, Make sure you are runing a good, up to date antivirus program in your computer. Run antivirus on mem cards BEFORE opening them on any file browser. Lets AV software finish scan before starting to transfer files.
4. Always practice good habits when inserting or removing cards from camera or computer. In camera always turn off camera to insert or remove cards. In computer make sure card access is finished before removing. Better yet use the USB /flash drive stop utility every time before removing.
5. Avoid strong magnetic fields around memory cards (speakers, TV sets, metal detectors, microwave ovens, electric motors, etc) although damage from magnetic sources is rare, it can happen.
6. Keep card's contacts clean, including fingerprints. Never allow them to get wet.
