Of course you have to manually go through that list of a trillion files and find which ones it found errors with, but then you can determine whether or not you want to through the files away... though I have found Virex to be completely accurate in finding virus files, I do not entrust any software to delete or install things on my drive without my approval. Software -- no software -- is that good.
