ahhh thanks a lot for your answers but i wasnt even able to dowload AVG because an error occured. I think its because of my other anti virus but I cant uninstall it cause its the videotron's one...haha Im afraid Ill screw up my computer so Ill just keep on pressing the x button on that stupid window8-) maybe this could get things worst?
AH WELL Ill find a way with the info you gave to me
