Head's up -- Adobe has now released new updates:
Flash Player v17.0.0.188 for IE and Non-IE browsers; the two new plug-ins are available as online installers for all OS at the main publisher's site, and most reputable downloading hubs will offer a redirect on downloading from their sites
Adobe AIR is now available at v17.0.0.172; this update is available as an online and offline installer at the main publishers site ( for those who need it as an offline installer, or for a different OS, make sure to click on the Need Adobe AIR for a different computer? click-line, then from the menu, just select the appropriate OS that you have and the variant installer version ) Most reputable downloading hubs will offer a redirection to the main publisher's site

Offhand: Make sure that once you download an offline installer, always scan it first with your updated anti-virus and anti-malware programs, and once you begin the process of installation -- Take it very slowly! Read everything, or you might end up installing PUPs ( Potentially Unwanted Programs ) There are already cases of popular, and well-known programs that are now bundled with PUP adware ( examples like OpenCandy ) and Browser redirection/hijacking ( examples like Ask Toolbar )
So when you're using offline installers -- create a System restore point first, then take it slow, and be careful

EDIT UPDATE: There has been an Tech article in regards to McAfee Stinger -- a second-opinion scanner in regards to malware infection/detection -- the update comes with something users are not informed of: it was installing a Windows-like service into the system called the McAfee Validation Service, which proves very difficult to remove ( the update has now been considered with such 'malware-like' behavior that some reputable downloading hubs are now pulling it out of their depositories to ensure the safety of users )
The only way to remove the said program and it's unwanted additional component is to download the McAfee Removal Tool and completely remove the program ( note that when someone installs the new McAfee Stinger, it does not create a System Restore point -- something that could have helped if anyone wants it removed safely )
