I just recently started getting this pop up while checking my email through AOL (I use AOL email, TCP/IP with cable modem).
It is from Macromedia Flash Player Security which is something I have never seen before. I have attached a picture of the pop up to this post. I don't recognize the "local application" nor the Internet enable location. Google turned up nothing.
I run Windows XP and I ran Adaware and SpyBot and both came back clean.
I did recently have a spoof email phishing for my ebay info, but I did NOT click any links within the email.
