Hi Rick in VA,· When exactly do you get this prompt from Windows Defender?ATWPKT2.sys is a file related to the AOL Connectivity Services. If you are using this program then you might want to allow the program in Windows Defender. Hope this information helps.Thanks and Regards,Santosh Y – Microsoft SupportVisit our Microsoft Answers Feedback Forum and let us know what you think.
