I have run Software Inspector, which tells me that Macromedia Flash Player 6.x
is insecure and potentially exposes your system to security threats!

The detected version installed on your system is 6.0.79.0, however, the latest
secure version released by the vendor, fixing one or more vulnerabilities, is
6.0.88.0.

I have tried to uninstall 6.0.79.0 but it comes back. I have 9.0.28.0
installed.

Do I have to bother?
