But if it's on my computer, it can theoretically
be run, with or without a browser.

True, but not a significant problem, IMHO. You can have a folder full
of viruses too, but unless they are =run=, there's no harm.

The problem isn't that [flash is] on the computer, but that it =runs=
when you hit a web site that wants it. Renaming the files or using a
different (flash-disabled) browser addresses that problem.

People should be using [html], not some third-party media tool.

Agreed, for the most part.
