"attaches itself to one of the cyber-security set-ups on the computer" - What does that mean?
I find the member's fears absurd. One should of course download an exe to one's computer before attempting to run it.
The download can take more than half an hour and the file size is 73,728,520 bytes.
Only then, when you have it on your computer, should you start it. It will then cleanly install clibgrab, which works excellently.
You may read about clipgrab by going to their website:
https://clipgrab.org/It has been in existence since 2007.
I have been running this forum for over ten years, so I think my judgement might be trusted.
