Hello Gail,
Thank you for contacting us. We see that you have an active license for AVG Internet Security. Do you have it installed on your PC and is it working fine?
Please note that Windows defender in the latest versions of Windows is acting like an anti virus program which may conflict with your AVG. So please let it remain disabled and be protected with AVG Internet Security.
Feel free to let us know if you require any further assistance.
my computer is telling me Windows Defender is not turned on. Should I have it turned on or does it interfere with my AVG protection. Gail
Gail, Windows Defender is a software product that attempts to detect and remove malware. It was first released as a free antispyware program download for Windows XP, shipped with Windows Vista and Windows 7 and made into a full antivirus program replacing Microsoft Security Essentials as part of Windows 8 and later versions.
