Downloading Zoom

I cannot download Zoom - webshield says its phishing

The Zoom exploit, is a flaw specific to Zoom, which you need to communicate with Zoom directly. I suggest you to ensure your computer operating system, and all programs (including Zoom), are updated to prevent exploits.
You may refer to their blog (https://is.gd/ZHFxlJ) regarding this.
