I had Adobe Reader 11.0.10 and I clicked on Check for updates and it mentioned it's up-to-date. When I went to the Adobe Reader official website it says that it has been named Adobe Reader DC 2015.007.20033. What does DC means? Even I use adobe reader on my smartphone and it has that version installed. Why did it still say it's up-to-date when I had Reader 11. Anyways, I installed Adobe Reader DC just in case if there would be a vulnerability for Reader 11.0.10. Reader and other program always has vulnerability.
Also why isn't Avast Software Updater doesn't detect this new version of Adobe Reader in the list?
