Ever since I switched back to Microsoft Defender Antivirus in January (after Xfinity stopped offering Norton for free), I have been receiving a persistent false positive on the file C:\Windows\Temp\cpnprt2x64.cid. It has been variously detected at different times as Adware:Win32/Coupons (most commonly), PUA:Win32/Presenoker, and App:CouponarificAds.


I consider this detection to be a false positive. I have reviewed the binary; it is a component of the Coupons.com printing application, which is activated only if you visit a coupon printing website and is required to print secure paper coupons online that most brick & mortar stores will accept. The vast majority of grocers and similar chains that accept manufacturers cents-off coupons now contract with Coupons.com to provide secure, printable online coupons. As Coupons.com coupons are almost always requested by the consumer, the software should NEVER be classified as "adware" or any other kind of malware.


I have flagged all three detections as "allowed threats" in Defender. However, Defender CONTINUES to flag this file as a virus and constantly attempts to notify me about it, quarantine it and/or remove it entirely. It is Defender that is engaged in unwanted activity, NOT this file. How do I PERMANENTLY stop Defender from treating this file as a virus?
