Flash player keeps uninstalling
On my acer laptop, everytime I turn the computer off, and try to view a video (particularly on facebook), I'm told I need to download that latest flash player.....which, of course, was already downloaded. I have windows 7, and have tried uninstalling and installing (latest version of flash player). It was doing this with windows explorer as well as with firefox. I've used CCleaner, CC Enhancer, Malwarebytes, and Spybot search and cleaned off anything that shouldn't be there (all under the instruction of a fellow from allexperts). No difference.
Any ideas?
