za inst that great, and that sounds like a corrupt file in windows, not really a virus, maybe the corrupt file was caused by a virus, or it could of been by a improper shutdown of your pc at a critical time.
My computer has had tons of improper shut downs cause of my retarded mom and it doesn't matter now my xbox hdd just crashed like just now,It makes a sound like its scraping against something and then makes some beeping sound so I'm gonna go shove a pickax through it or something because I am super pissed right now.
unless somebody knows about that llama thing where you can send in your broken xbox and get a new one for free.
I made i short vid of what happens and here it is. also sorry for the crappy quality i recorded it on my phone
