Safe mode is a diagnostic mode of a computer operating system and provides access to diagnostic programs so a user can troubleshoot what is preventing the operating system from working normally. Most viruses are inactive when using Windows in Safe Mode and they can be easily removed because Windows loads just the basic drivers and a minimum of operating system components, so only a few applications work.
