Hi and welcome to the DP.

There is no such thing as a "hex value". Hexadecimal is merely the representation of a number, so is octal and decimal. The point being, that all are equivalent, no matter how you represent them.

Which particular AV software dumps what into a text file? I think you are lacking some very fundamental basics, so you shouldn't start with an AV software. It's certainly possible for one person to write one, but firstly most AV companies started years ago (most of them far more than a decade ago, some two decades ago) and secondly it will take not only time but also a lot of skill. While you may have the time, the skill is a prerequisite - it won't be enough to acquire it over time, because essentially you'll find at some point that you have completely screwed up your design and you can start over from scratch.
