How do I remove it? I've tried Avast, hitmanpro, malwarebytes, and Revo uninstaller, the problem remains: Every time I change from one window to another, the same box pops up at the bottom of my screen: "This webpage wants to run the following add-on: 'Adobe Flash Player' from 'Adobe Systems Incorporated'." This virus also seems to be associated with Java and Oracle. It interferes with my playing video clips on some (not all) sites -- I get a message saying "Most Recent Version of Adobe Flash Player required." But I know I HAVE the most recent version, I just downloaded it direct from the Adobe website, after uninstalling everything "Adobe" in my program directory.
This is not malware, but your browser's security settings. It is up to you to lower them.
