Basically, I can't drag files or folders anywhere, same for files inside archives, and I cannot even access to the system in automatic when I turn the computer on, because it boots (BIOS?) at the begin and I have to choose if I want my Hard Drive or my CD/DVD drive. Obviosly I choose the Hard Drive, but once I access the problem of the undraggable files remain. Anti-Antivirus or anti-rootkit tools does detect nothing.

EDIT: Apparently, using this solution which consist in pressing the ESC key while selecting a file rehabilitates the the drag and dropping for a while. I'll see if I can resolve the rest.
