I opened my laptop (Win 7) and all the desktop programs are missing. There are no files in C: and Start Menu. This program called System Restore opened up and started to scan my program. In the notification tray this message pops up saying "critical error". I tried to download MWByte but it can't be installed. This message "Access is Denied" is displayed every time I try to install. I don't know what to do. Any help will be appreciated! Edit to add text from duplicate tread which has been deleted: Please keep all logs and information for this problem on this thread.
