So I didn't update my MBAM for a week. Today I decided to update it and I got a message saying the definitions is missing or corrupt and asked if I would like to download a new copy. I said yes, and it seemed to update fine. It told me that the definitions version updated from a buncha 0s to the current one. My questions are:
1) Why did it tell me the definitions are missing/corrupt?
2) Since it seemed to update correctly, does that mean the program will work fine?
