After over 200 files being false positives that I know were not infected, Tech Support emailed and recommended installing the latest BD version 2014 which supposedly fixed the false positive issue. Having done that, it performed a scan and informed me it found infected files and the "problem" was resolved. It doesn't log which files were deleted, but now Battlefield 3 was rendered unusable, even the installer files were deleted. Now I must re-download the 20+ GB file again and reinstall.
I wonder how many other programs are corrupted because BD automatically deletes "infected" files without notifying, in addition to the ones already bricked.
Very, very frustrating.
