The Quick Heal AV parsing engine (November 2019) allows virus-detection bypass via a crafted GPFLAG in a ZIP archive. This affects Total Security, Home Security, Total Security Multi-Device, Internet Security, Total Security for Mac, AntiVirus Pro, AntiVirus for Server, and Total Security for Android.
Product A handles inputs or steps differently than Product B, which causes A to perform incorrect actions based on its perception of B’s state.
