So I have partitioned 3 different computers in part of the BoS quest "still in the Dark". I did them all on differerent attempts, one at a time actually. They guy is still asking me to search of viruses but I havent been able to find any others and those computers that I had found the viruses on have stayed partitioned, anyone know if I doing something wrong or if its a bug and if it is a bug is there a way around it?

Sounds like a bug, as long as all 3 partitions are still in place, it shouldn't matter how many tries it took (I did it in 4 tries, and was able to complete the quest).
