Unreliable Interface and Operation

AVG unexpectedly deleted files in categories that I did not select. System files? I pray not! In any event, now I cannot put them back, because this program does not have a log file or the ability to back out of mistakes. Perhaps I misunderstood the interface? Or maybe this freeware has not been sufficiently thought-through. This is a warning to any potential users - FIRST create a backup of your system (CCcloneer, etc) and then be absolutely clear on the operation of this poorly documented software PRIOR to use.
