Wadware: The Sneaky Software and How to Protect Yourself




Have you ever downloaded a free program that suddenly bombarded you with unwanted ads, changed your browser homepage, or slowed down your computer? If so, you might have encountered wadware.

This article will explain what wadware is, how it infiltrates your device, and the steps you can take to protect yourself and remove it.

What is Wadware?

Wadware is a type of malicious software (malware) designed to display unwanted advertisements on your computer or mobile device. Unlike traditional pop-up ads, wadware is more intrusive and can be difficult to remove.

Here’s a breakdown of how wadware works:

  • Infiltration: Wadware typically enters your device through:

    • Deceptive downloads: You might download software bundled with wadware, especially from unreliable sources.
    • Malicious email attachments: Clicking on an infected attachment can install wadware.
    • Drive-by downloads: By simply visiting a compromised website, wadware can exploit vulnerabilities to install itself.
  • Activities: Once installed, wadware can:

    • Generate constant pop-up ads that disrupt your browsing experience.
    • Redirect your web searches to generate ad revenue for the attacker.
    • Modify your browser settings, such as your homepage.
    • Track your online activity and collect personal data.
    • In severe cases, slow down your computer or even damage system files.

Signs of Wadware Infection

Here are some signs that your device might be infected with wadware:

  • A sudden increase in pop-up ads, even on websites that typically don’t display them.
  • Your browser homepage or search engine has been changed without your permission.
  • Your computer is running slower than usual.
  • New toolbars or extensions appear in your browser that you didn’t install.
  • You’re constantly redirected to unfamiliar websites.

How to Protect Yourself from Wadware

  • Download with caution: Only download software from trusted sources and official websites.
  • Beware of freeware: Free software can be a breeding ground for wadware. Read reviews and be cautious during installation, opting out of any bundled software you don’t recognize.
  • Scrutinize email attachments: Don’t open attachments from unknown senders, and be wary of even familiar email addresses if the content seems suspicious.
  • Keep your software updated: Regularly update your operating system, web browser, and security software to patch vulnerabilities that wadware might exploit.
  • Invest in a good antivirus: A reputable antivirus program can detect and remove wadware infections.
  • Use a pop-up blocker: Consider adding a pop-up blocker extension to your web browser for an extra layer of defense.

How to Remove Wadware

If you suspect wadware infection, follow these steps:

  1. Run a scan with your antivirus software. Most antivirus programs can detect and remove wadware.
  2. Check your browser extensions. Look for any unfamiliar extensions and remove them.
  3. Reset your browser settings. This will restore your browser to its default configuration and remove any unwanted changes made by wadware.
  4. Consider a dedicated anti-malware scan. If the above steps don’t resolve the issue, consider using a specialized anti-malware program to target wadware specifically.

FAQs about Wadware

If you’re struggling to remove wadware on your own, consider seeking help from a computer technician or contacting your antivirus software provider for support.


Wadware can be a nuisance, but by following the tips in this article, you can protect yourself from infection and remove it if it infiltrates your device.
