^^...i've been using it too... ...but after the end of support i immediately dropped this tool and 'replaced' it by the 3rd party uploader 'WinJa'.
i dropped the VT uploader years ago because of possibly bugs... ...and yes, also because of possibly security risks.
...im always trying to run the latest version/release of a software product.

You can also use the official browser plug-ins to directly scan/send files and links to 'virustotal.com' from within Firefox/Chrome/IE:

source: VT4Browsers – Get this Extension for 🦊 Firefox (en-US)
Or simply bookmark the VT-Site. (y)
Don't really see the need of an extension in this case.

OK, so you'd like to try out a new program and SmartScreen gives you a warning that the publisher is unknown.

What steps do you take to minimise risk of infection or do you simply not run this program?

It is best to run such a file on a virtual machine (for example, VirtualBox) and see what happens.
There is also such a service from Kaspersky - Kaspersky Threat Intelligence Portal
