First of all, I´ve never installed this crap. Flash has the sole purpose of littering my computer with all sorts of marketig garbage. Now it showed up out of the blue, embedding spams in my youtube videos. When I right-click the ads, it shows "About Adobe Flash Player version xxx". I click on Adobe and it takes to their website, where it detects: You have version 11,8,800,97 installed.
- I followed Dominc´s + all above instructions step by step, all worked fine until the uninstall was concluded. I went to the Library, but could NEVER find what I was supposed to delete. I found the folder Internet plugin, the both Flash files were not there.
- After that the the ads keep popping up in my youtbe videos.
- Adobe website keeps giving me the message: You have version 11,8,800,97 installed.
- I restarted the computer, all the same results: Adobe detects my installation + ads popping up on youtube.
What happened to Apple?! It´s like Windows now infecting and hijacking computers? Please help me. If I can´t solve it here I´ll have to go to an Apple store, send it to repair.
