Ad Injection

What is ad injection?

Ad injection is a technique that websites use to generate money from online ads. This makes it more difficult for you to browse without being constantly bombarded by pop-up ads and other content. In fact, these injected ads can sometimes lead to malware and viruses on your computer. As a result, this invasive practice of injecting advertisements into webpages may affect your computers speed and security online.

How does it work?

Typically, ad injection is conducted through programs that redirect a user’s browser to display ads. The process can sometimes be altered by placing code on your computer that causes it to look for and inject ads into websites you visit.

How can I protect myself from ad injection?

To guard yourself against ad injection, make sure you have malware and antivirus protection with firewall capabilities. Only use trustworthy sites for banking or shopping online as these are typically targeted more by hackers who want to steal personal information (like credit card numbers). Also, avoid accessing the internet via public WiFi networks in cafes and malls since other people who are connected to the network may be using it maliciously to send viruses and other harmful material directly onto your device. Some apps like AdAway or AdBlocker for Chrome can be used on Android devices to block ads in apps and browsers.

Why should I worry about ad injection if I’m using public WiFi?

It’s possible that people who use the same public WiFi network could have malware programs on their devices. This allows hackers to access your computer and steal personal information without you knowing it. Plus, when you do not know who is accessing a network, you cannot trust anyone connected to it as they may be trying to steal information from others online (like credit card numbers).

It’s always best to avoid accessing the internet on public WiFi networks whenever possible.

How can I avoid ads when browsing with my Android?

There are several apps you can use that will block ads (some even work for iOS as well). One example is AdAway, an open-source app that works by “flashing” a custom ROM for your specific phone model and then taking away the system-level ad services so that no apps can inject any ad code into any web pages or other apps without permission. Other options include AdBlocker for Chrome which blocks all advertisements in both Incognito mode and regular mode.

A list of browser extensions that prevent sites from tracking your personal information and browsing history

  • AdBlocker for Chrome – blocks all ads in Incognito mode as well.
  • AdAway – allows you to block ads at the root level so they don’t appear on any web pages, including within apps.
  • Ghostery – lets you view and block trackers that are embedded in websites. This is especially useful when visiting a new site where you do not know which trackers are being used to collect your data.
  • uBlock Origin – prevents sites from tracking your online behavior and speeds up webpage load times.
