Once you act like you are going activate the Security Defender from one of the pop ups, you click activate, but then it will prompt you to choose, activate now, or I have already activated, but enter my code.(something like that. You choose to already activated, and enter my code. Then, the code window will come up, to enter the code. If you choose to activate now, the window will come up for you enter your information to purchase it first, so choose the other choice to enter the code. I rebooted afterwards, and so far so good. Thanks a million. Glad there is help out there with these types of situations.
2015 UPDATE: Appears that Security Defender has changed their site – the Code solution above no longer works. McAffe scans that ‘quarantined’ the problem are not effective, and SD blocks every attempt to use an application or reach a website on IE. Can’t download anything from Spyhunter of Malwarebytes becuse I can’t get there.
