Needed for PGP plugin in MS Outlook. When disabled Outlook crashes sometimes. Does not seem to use much ressources ( 5 MB RAM, rarely any CPU).
the dirmngr deamon ( windows service) is part of the GnuPG package. It is a server for downloading certificate revoke lists.

It's used for PGP, it's NOT a virus!
If it is part of Gpg4Win then the SW author should add something in the manufacture column. Easy fix to much confusion.

Best practices for resolving dirmngr issues

A clean and tidy computer is the key requirement for avoiding problems with dirmngr. 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 dirmngr.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.
