    My ASUS laptop came with Mcaffee activated, and I want to run Windows Defender, since its FREE. I tried disabling the Mcafee firewall. But DEFENDER still wouldn't activate. It kept saying another AV is running, check security action center. It seems as though Mcafee has HIGHJACKED my machine, and trying to FORCE me to pay for their service. Any help will be much appreciated.

    Uninstall Mcaffee & defender should work.

    You can find the McAfee uninstaller here.
