A virtual instrument (VI) file is similar to any executable file such as EXE and DLL. You should exercise the same precautions with a VI file as you would with a EXE or DLL file.
The following guidelines help protect you from security issues related to VI files:
- Only run VI files that come from a trusted source. VI files downloaded from the Internet or received by e-mail should not be trusted.
- Only run VI files from a safe location such as a protected Windows directory or a directory where you control the access permissions.
If you want to safely inspect a suspect VI before running it, follow these steps:
- Create a blank project
- Add the suspect VI to the project as a sub-VI
- Inspect the sub-VI's code
