Adobe software is highly recognised and popular amongst business users. I have Adobe Acrobat DC installed on some computers, as features available are required by the UK Government. They create very good products, for example, Adobe Photoshop and Premiere Pro are used in education and by professionals, and many others.
I would rather use Adobe Flash Player than Microsoft Silverlight for viewing online content, say 5 years ago.
Just like Windows compared to Mac.There are more attacks on Windows because it is used so much more than Mac and is the OS for most every Business,Government and Institutional agencies.
Problem isn't Adobe it's that they make products that are used more than other products.I have never had a problem using Adobe products,you just have to make sure you update it like anything else.
