AcroTray.exe is normally an Adobe Acrobat background component used for PDF-related actions such as conversion, printing workflows, and Acrobat integration. It is not a Windows system file. In most cases it is legitimate, but malware can copy the name, so the file location and signature matter.

- Usually no. The legitimate file belongs to Adobe Acrobat.
- It is suspicious if it runs from
AppData,Temp, Downloads, or a random folder. - It is suspicious if there is no Adobe digital signature.

What is AcroTray.exe?
AcroTray.exe is part of Adobe Acrobat and helps Acrobat handle PDF actions in the background. It may start with Windows after Acrobat is installed. This is why users often notice it in Task Manager even when Acrobat is not visibly open.
