When updating Flash Player, how do I stop McAfee from installing?

[firstcharmedone]

Flash Player updates automatically reinstall McAfee and as this conflicts with my own security system I don't want it to automatically install but don't know how to stop it.  Can someone help?

There's a checkbox BEFORE you download Flash Player, that prevents the download and install of McAfee. Uncheck it and it won't download.
