belongs to my soundchip Realtek
Part of my sound card from Realtek
ASUS Realtek
it appears in c:\windows every time I have a problem, icons change etc
nothing i need to kno what this program is in more detail
belongs to an installation of the driver for Realtek-onBoard-Sound, but it seems to be completely useless, no need to run another risky process
It has a spider-like logo in c:\windows. Looks dangerous. Similar to ALCMTR and ALCWZRD
I have this file and a RealTech soundcard. It seems there's a connection...

It is part of the Realtek Sound Manager program for Realtek integrated sound devices. It is neither dangerous nor useless. Realtek Sound Manager may also come with AvRack, a media player shipped with the installation of the managing software. As for that spider logo, it belongs to Realtek as well. :) Happy listening!

Best practices for resolving alcfdrtm issues

A clean and tidy computer is the key requirement for avoiding problems with alcfdrtm. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
