• On Microsoft Defender, it is known as Trojan:Win32/Dynamer!ac.

Should I remove or uninstall un.exe?

The simple answer is yes. You may remove it for any of the following reasons:

• It is associated with malware and may download and install other malware on your computer.
• The program may steal personal information like passwords and credit card numbers.
• It is not a core Windows file; its removal will not hinder any processes.

How do I remove un.exe?

In some cases, a simple delete may suffice. But we recommend also deleting it from the recycle bin or permanently deleting it using Shift + Del.

We, however, still recommend a virus scan after deleting the file.

Where is the un.exe file located?

Usually, the file may be found in the Windows temporary files folder shown below, and this may be your first scan location if you are looking to get rid of it.

C:\Users\user name\AppData\Local\Temp

It has no file description and a file size of about 3,714,048 bytes. The application is invisible, so you may have to enable hidden files to see it.

By getting rid of un.exe you will protect your computer and your personal information. While we discussed using the inbuilt Windows Security tool, you may also try some other robust antivirus software for Windows 11.
