Part of Microangelo Safe to use

A program that lets u change your desktop and icons around
Possible virus infection if located in C:\Windows\System32 or C:\WINNT\System32 (depending on the operating system). This program attempts to access the Internet and if successful, continues to send and receive data without your permission. ZoneAlarm Pro will ask if it can access the Internet and it will name itself "Windows Help Service". Deny all access to it via your firewall if it makes such a request. Always check where the file originates from.

We had a handfull of workstations and most servers running this file from the system32 folder. It was sending packet requests to port 445 on our firewall. I cratered the firewall. We treated it as a virus.
The file "muamgr.exe" is part of Microangelo's Studio and Creation software programs. Both Studio and Creation programs were created by Impact Studios under the brand name "Microangelo", and are used to create custom static and animated icon files for desktop, folders, and hard drives. Muamgr.exe adds an "Appearance" option to the context menu of programs, folders, and hard drives of Windows operating systems. The "Appearance" option, muamgr.exe, allows the user to change the icon for a selected program, folder, or drive. The file is launched on start-up, because it maintains and manages the custom icons that it has been used to install. Muamgr.exe is ALWAYS found in "C:\Program Files\Microangelo\" program directory and is 72KB in size. Managing and maintaining custom icons is the sole function of muamgr.exe. It does not gather data for online transmission to a third party. The only data that it accesses and stores is the data is necessary to correctly assign custom icons to specific applications through user input. If muamgr.exe is found anywhere other than the Microangelo program directory, then it was not installed by Microangelo software and should be treated as a suspicious file. Muamgr.exe should not be found on any computer that does not have Microangelo software installed. If it is present on a machine that does not have or has not had Microangelo software installed, then it is not a valid Microangelo/Impact Software file and should be treated as a virus and eliminated. A legitimate muamgr.exe file will never be found in the system or system32 directory under any legitimate circumstances.

Best practices for resolving muamgr issues

A clean and tidy computer is the key requirement for avoiding problems with muamgr. 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 repairing of your installation or, for Windows 8 and later versions, 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 muamgr.exe 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.
