What is pdfx-updater.exe?
pdfx-updater.exe is the updater component for the PDF-XChange suite from Tracker Software. It periodically checks Tracker Software servers for newer versions of PDF-XChange Editor, PDF-XChange Viewer, and related components, downloads installers, and installs updates to keep your applications secure and feature-complete.
The updater communicates over secure channels to fetch signed update packages, verifies the digital signature, and then applies patches either automatically or on user approval, depending on settings.
Quick Fact: The updater enables silent background updates when configured, reducing manual download steps and helping prevent vulnerable versions from staying on your system.

Is pdf-xchange-updater a Virus or Malware?
The updater is not a virus. However, malware can masquerade as legitimate updater files.
How to Tell if pdf-xchange-updater is Legitimate or Malware
- File Location:: Must be in C:\Program Files\Tracker Software\PDF-XChange Editor\PDFXCUpdater.exe or C:\Program Files (x86)\Tracker Software\PDF-XChange Editor\PDFXCUpdater.exe. Any other path is suspicious.
