What is Wadware? Unwanted Software You Didn’t Ask For

Have you ever downloaded a free program and ended up with a bunch of unwanted software on your computer? If so, you’ve likely encountered wadware. Let’s delve into what wadware is, how it works, and how to protect yourself from it.

Wadware Defined

It is a type of unwanted software (UWS) that gets installed on your computer without your explicit consent. It often bundles itself with legitimate free software you download from the internet. While not necessarily malicious in the same way as viruses or malware, it can be a nuisance and can negatively impact your computer’s performance.

How Does It Work?

It employs several tactics to infiltrate your system:

  • Bundled Software: This is the most common method. It gets packaged together with the free software you download. During the installation process, the installer might have pre-checked options to install additional software, including it. If you don’t carefully review the installation steps and blindly click “Next,” you might unknowingly install wadware.
  • Deceptive Downloads: Some websites might trick you into downloading wadware by disguising it as something else, like a codec pack or an update for your system. Always be cautious about downloading files from untrusted sources.
  • Drive-by Downloads: In rare cases, malicious code on a website can automatically download and install wadware on your computer without your knowledge. This typically requires security vulnerabilities in your web browser or operating system.

What Is It Doing?

Once installed, It can exhibit various behaviors:

  • Displays Ads: This is the most common way wadware makes money. You might see pop-up ads, banner ads, or even ads that inject themselves into webpages you visit. These ads can be intrusive and disruptive.
  • Tracks Your Activity: Some it might track your browsing history, search queries, and other online activities. This information can be used for targeted advertising or even sold to third parties.
  • Changes Browser Settings: It might modify your default search engine or homepage, making it more difficult to navigate the internet.
  • Slows Down Your Computer: It can consume system resources, leading to sluggish performance and crashes.
  • Installs Additional Software: In some cases, it might even download and install other unwanted software on your computer, further cluttering your system.

How to Protect Yourself

Here are some steps you can take to prevent wadware from infiltrating your computer:

  • Download from Trusted Sources: Only download software from reputable websites and developers. Avoid downloading programs from unknown sources or through pop-up ads.
  • Read the Fine Print: During installation, carefully read the license agreements and installation screens. Uncheck any pre-selected boxes that agree to install additional software.
  • Use a Reputable Antivirus Program: A good antivirus program can detect and block many types of unwanted software, including it. Keep your antivirus software updated with the latest definitions.
  • Use an Anti-Malware Program: Consider using a dedicated anti-malware program alongside your antivirus software for an extra layer of protection.
  • Be Wary of Free Offers: If something seems too good to be true, it probably is. Free software often relies on advertising or bundling with other software to generate revenue.
  • Keep Your Software Updated: Regularly update your operating system, web browser, and other software applications. Updates often include security patches that can help prevent vulnerabilities exploited by this.
  • Consider a Custom Installation: If available, choose a “custom” installation instead of an “express” installation when installing software. This allows you to see exactly what components are being installed and deselect any unwanted software.

Removing Wadware

If you suspect wadware has infiltrated your system, there are ways to remove it:

  • Use Your Antivirus/Anti-Malware Program: Most antivirus and anti-malware programs can scan for and remove it. Run a full system scan and follow the program’s instructions for removal.
  • Uninstall Unknown Programs: Check your Control Panel (Windows) or Applications folder (Mac) for any recently installed programs you don’t recognize. Uninstall these programs carefully.
  • Manually Remove Browser Extensions: Review your web browser’s extensions and remove any suspicious or unfamiliar ones.
  • Reset Your Browser Settings: Consider resetting your web browser’s settings to their defaults. This can undo any changes made by this, such as modifying your homepage or search engine.
  • Seek Professional Help: If you’re struggling to remove wadware yourself, consider seeking help from a computer technician or tech-savvy friend.
