Safe Mode is a diagnostic operating mode, used mainly to troubleshoot problems affecting the normal operation of Windows. Such problems range from conflicting drivers to viruses preventing Windows from starting normally. In Safe Mode, only a few applications work and Windows loads just the basic drivers and a minimum of operating system components. This is why most viruses are inactive when using Windows in Safe Mode, and they can be easily removed.
