An error occurred while opening PDF file
Hi friends, I have here an error message that I encountered while opening my PDF file, the error message is telling that the file could potentially harm your computer, please refer below the whole text of the error for a clear view of my concern.
Launch File
This file and its viewer application are set to be launched by the PDF file. The file may contain programs, macros or viruses that could potentially harm your computer . Only open the file if you are sure it is sage. If the file  was placed by a trusted person or program, you can click Open to view the file.Â
As I read on the error I was confused and afraid what might happen to my computer, so I choose don't open, and I scan my computer for some virus that might infect my computer, but no virus was found, so I am asking for some advice, should I continue to open the file,
Please share your ideas,
Thanks.
