this is used to make the system speaker go BEEP whenever an application requests it, or when an error message poppes up but you don;t have a sound card installed to hear the default ploing sound.

Beep.sys is the driver for the beep installed in the computer, some computers its has adjustable volume, others it just loud.

This file generate bips for ms-dos, and is not dangerous, but a system file. Try it launching cmd.exe and write: "echo " then press Ctrl+G and press Enter. Never delete this file. It is used when you haven't got any drivers for sound. It is a non-plug-and-play peripheral and a system service.

Beeping can be disabled from Device Manager, to find it select Device Manager to show all hidden drivers, it is under plug and play

should be about 4.1 kB, but i found a much larger file there. i replaced it with windows' original copy (from windows xp cd), and the system kept running fine.

My symantec antivirus keep seeing it as a threat

I've deleted it, and that echo ^G still causes a beep.

It prevented Windows XP from booting up. The diagnostic screen told me to disable or remove any newly installed hardware or software. And/Or disable BIOS memory options such ascaching or shadowing, using,if necessary, the F8 Safe Mode operation. I don't know how to do this so I will probably take it in to a computer service shop.

Beep.sys can be infected. Buretos.exe depends on it to keep you infected.

personally got sick and tired of system beeps and disabled the driver in device manager this will cause no detrimental effects to your machine so enjoy the silence. unfortnatly this does nothing to stop the bios from beeping it's heart out durring post
  mike  
it's system file not to be confused with ANY sound file. charisteristics of this file are hidden, but it is a building block for an Operating system to function correctly .
  panic!!  
if a program call for it and it is not installed, the os can crash

Best practices for resolving Beep issues

A clean and tidy computer is the key requirement for avoiding problems with Beep. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the Beep.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
