I am pretty sure this is a false positive. I was downloading coupons from a legitimate website, which uses a coupon printer in the form of an ActiveX control. I have used this system many times over the past several months, and only recently did ZoneAlarm flag Win32.Coupons.h as adware. While ZoneAlarm was displaying its status message about this, the coupon installer was showing an error in extracting the contents of one of its files.
