Thanks, Jo*mar! I went to
http://www.adobe.com/software/flash/about/ and it says "You have version 21,0,0,213 installed" . One thing I read somewhere said "Adobe notes that the vulnerability has been actively exploited on devices running Windows 10 and earlier with Flash Player version 20.0.0.306 and earlier." Sounds like I'm updated, right?
On the Adobe website above, there's no mention of a pending update.
