Runtime errors are the most common form of EXE error you will encounter using Norton Security Premium.

In most cases, FSDUI_NSBU.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these FSDUI_NSBU.exe error messages mean that Norton Security Premium was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process.

Finding the source of the FSDUI_NSBU.exe error is key to properly resolving these errors. Although most of these EXE errors affecting FSDUI_NSBU.exe will happen during startup, occasionally you will encounter a runtime error while using Norton Download Manager. This can occur due to poor programming on behalf of Symantec Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

CAUTION : We strongly advise against downloading and copying FSDUI_NSBU.exe to your appropriate Windows system directory. Symantec Corporation typically does not release Norton Security Premium EXE files for download because they are bundled together inside of a software installer.
