I decided to provide some more information since I’m still having the same issue and don’t want to add soffice.bin to the exclusions list. I hope the information below helps identify the issue.

  • Program version: 7.0.317799.4142
  • Database version: 20292
  • Antivirus setting: Stateful
  • Auto-Sandbox setting: Partially Limited
  • HIPS setting: Disabled
  • File path: C:\Program Files (x86)\LibreOffice 4\program\soffice.bin
  • LibreOffice version:
  • Operating system: Windows 8.1

I checked the Defense+ log and discovered that when Comodo Internet Security checked soffice.bin online, it found it to be malicious. In addition, soffice.bin shows up under Unrecognized Files. When I manually looked up the file, it says it is an unknown file. I also checked Trusted Files and soffice.bin is not on the list. I wonder if it should be added.

Should I attach soffice.bin to a post in this thread?

Hi Jesant13,

Can you upload your soffice.bin file to and post the link here so that Comodo can possibly investigate this further?

By the way, your libreoffice is out of date, try updating it to the latest version and see if that resolves this problem.

I uninstalled both Comodo Internet Security and LibreOffice and installed the latest stable versions of both. I am no longer experiencing the issue.
