Google Publisher Tag
Google Publisher Tag (GPT) is the JavaScript library that requests and renders ads from Google Ad Manager. ScanMalware detects it from the gpt.js loader and its ad-slot definitions.
Ad libraries pull creatives from external networks, which makes them an occasional channel for malvertising. The presence of GPT is a cue to check what the ad slots actually load.
