Not very well, I'm afraid.
Long time ago, I prepared most of the "low level stuff" (extraction of the important information from files, special compression of the data, fixing the infected file), but since then I didn't have time to do the "high level stuff" as well (the management of the database and the actual testing). There are still more important things to do

I'd say that I would like to finish this feature, but it probably isn't a top priority right now, because file infectors are quite rare today...
