No.

Although you're more at risk of being hacked if you don't.

My advice is to get a standalone (non-network, non-Internet) p/c and use that one for all your sensitive information.

Unfortunately any p/c that connects to the web these days is going to annoy you with these updates unless you either uninstall the software requiring it or you dig around in the documentation for whatever software it is to find where the setting is for "check for updates automatically" and disable it. Otherwise you'll have to keep selecting "don't download" every time it asks you. It's monumentally annoying I agree.

The worst are the windows ones that require a frikkin' reboot every time. Sometimes it doesn't even ask - it just hijacks your computer and restarts it for you, whether your work is saved or not! Fortunately you can disable this.
