PDFOnline-express is the program delivering advertisements from malicious networks and redirecting to suspicious websites. It injects various web pages with commercial content and modifies browser settings. The pop-up even states that this program can read and change data on the websites you visit. The message shows up on the screen before installing the Google Chrome extension manually. Unfortunately, in most cases, the installation of this addon happens without users consent or knowledge, and the unwanted PUP behavior appears out of nowhere.

PDFOnline-express ads extension reads sites that you visit and injects them with additional commercial content, but the PUP can access and gather data about your other online browsing preferences and activity. Such applications track this information for marketing purposes. All the personal details about you can later be used in personalized commercial campaigns, so the more time the PUP has on the device, the more advertisement you receive and time online diminishes significantly.[1]
