How do I find and delete flash cookies?

This article below says that Disney Corp. and others maliciously installed flash cookies, which are undetectable and undeletable in the normal ways that apply to regular cookies.

So how does one find flash cookies? How does one delete them?

I currently use Spybot, Anti-Malwarebytes, Threatfire, plus one major antivirus program. Do any of these already solve this issue?
