In July I told you that Adobe finally announced that it will be retiring its Adobe Flash software.  However, until that time, they are issuing new security updates and if you are  user of Adobe Flash, you absolutely should install the latest security patches, such as those just released by Adobe as indicated in a link below.
Flaws in Adobe Flash have been exploited by hackers and identity thieves against individuals, companies and government agencies including the U.S. State Department and the White House.  In 2010 Steve Jobs vociferously complained about its security and it has routinely been cited as being extremely vulnerable.  Despite security patch after security patch, new problems keep coming up.  According to security company, Symantec in 2015 80% of the newly discovered software vulnerabilities which can be exploited by malware created by cybercriminals involved Adobe Flash.
Microsoft already blocks Adobe Flash by default in its Edge browser due to security concerns.  Microsoft also blocks outdated versions of Adobe Flash from running in Internet Explorer on Windows 7.  If you use Windows 8.1, Windows 10 or Windows Server 2012R2, this will not affect you because these systems automatically install Adobe Flash security patches.  In addition, to Microsoft Google, Apple and Mozilla block Adobe Flash.   Apple has blocked Adobe Flash from iPhones since 2010.  If you have not already switched to alternative software to Adobe Flash, now is a good time to do so.
