Hello, I just try to upgrade Pro Mountain Lion, but the administrator password pointed out as wrong. I tried to reset, but just not possible because it needs the old password, and unfortunately i not have enabled the option to reset the Apple ID. Appeared a window flash update hours before, I do not know if there is any connection or if it can be a really malware, because I also thought that someone could have changed my password remotely, but it is virtually impossible. Does anyone have a recommendation of some anti virus that can do a full scan? Another option that I thought would be to create a bootable disk and do a clean install, but do i not want to lose all my data from Mac. And sorry for my english. Thanks!
