What is SumatraPDF?

SumatraPDF virus

SumatraPDF is not a realistic or potentially safe alternative to Adobe Acrobat or even viewing a PDF file in an internet browser window. When using SumatraPDF to view a PDF file, you will need to upload the file in the program, and the file will then appear on a random website that may not intend to delete the file you shared with them.


SumatraPDF seems to also serve a purpose to advertise PDFixers and other tools that cost money to use.

Is SumatraPDF a virus?

SumatraPDF is not essentially a computer virus, nor malware; it is currently detected as a PUP by various antivirus programs according to VirusTotal, a free online service that analyzes files for potential malware threats using multiple antivirus engines and provides users with a comprehensive report detailing any detected issues to help assess the safety of digital content.

Although it is not considered a virus, there are a striking number of concerns with the program:

  • Lack of realistic functionality
  • Contains Advertisements
  • Bundles with potential malware and viruses
  • Advertised by malicious advertising networks
  • Utilizes potentially deceptive advertising campaigns
