Hidden files and folders option cannot change Log Attached

A couple of days ago a friend told me that he couldn't view his hidden file s and folders and whenever he changed the setting to show them it just went back to hide.Bitdefender and Spyware Doctor found numerous infections and one was Rootkit Agent QV which even though Spyware Doctor removes it, it seems to reinstall itself after restart.This is the Hijackthis Log.
