I like the concept :)
Would be nice to have more of an objective or mechanics other than only running over files and corrupting them
I did notice a few issues. When I died and game restarted, there were no new files for me to corrupt and secondly, if you move diagonally you move faster (probably faster than intended), and it became too easy to out run the anti viruses.
I can definitely see how this idea can be expanded on with more mechanics!
Edit: I feel like this is what is happening your game:
