Website publishers often use advertising services like Adnxs.com to generate revenue on their sites. Unfortunately, in some cases, threatening programs generate revenues by redirecting users to websites like Adnxs.com without the publisher's permission. Adnxs.com advertisements usually promote unwanted chrome extensions, fake surveys, adult websites, dubious online games, fake software updates and other potentially harmful tools and applications.
The Adnxs.com pop-ups can show up on a computer because a Potentially Unwanted Program (PUP) has sneaked in without any notice. That is the case when the advertisements appear continuously, and it is impossible to turn them off, especially. Also, affected users may have visited some unsafe website that has been designed to redirect to this page accidentally.
Such behavior of a browser leads to a decreased browsing experience and endangers the affected device's safety. Most PUPs likely have data tracking abilities and collect personally non-identifiable information like web browsing history and used search keywords. The data can, later on, be used to generate custom commercial ads based on user’s online likes and preferences. Users can prevent such an undesirable outcome by running a thorough malware scan with a reliable anti-virus program and removing any detected issues.
