Adware

« Back to Glossary Index

Adware is software that displays unwanted advertisements on a user’s device. Often bundled with free programs, it generates revenue for developers by promoting products or services, but it can disrupt the user’s experience and compromise privacy.

What is Adware?

In the digital age, where online experiences are an integral part of our lives, encountering adware is not uncommon. Adware, short for “advertising-supported software,” is a type of software that primarily exists to display advertisements on your device. While not all ads are harmful, malware tends to push the boundaries, bombarding users with often intrusive, disruptive, and occasionally malicious ads.

How does Adware work?

Understanding how malware operates is crucial in defending against it. Malware typically infiltrates your device when you download and install free software or apps from the internet. It is particularly tricky because it often comes bundled with legitimate software packages. In their eagerness to obtain the desired software, users may overlook the fine print that allows malware to sneak onto their devices. Once inside your system, malware monitors your online behaviour, collecting information about your interests and browsing habits. It then uses this data to display targeted ads, hoping to generate revenue from clicks and views.

Common Characteristics of Adware

Adware often exhibits several common characteristics that set it apart from regular software:

Excessive Ads

One of the most telltale signs of adware is the onslaught of advertisements. It tends to go overboard, bombarding users with pop-ups, banners, and auto-playing videos.

Browser Tampering

Adware may take the liberty of changing your browser’s homepage search engine, or installing browser extensions without your consent.

Performance Degradation

Many users notice that their devices slow down significantly when infected with adware. This degradation in performance is a direct result of the adware’s resource-intensive activities.

Data Tracking

Adware often engages in extensive data tracking, monitoring your online activities, and collecting information about your browsing habits.

Bundling with Free Software

Adware typically piggybacks on the installation of free software. Users unwittingly agree to its installation when accepting terms and conditions.

Types of Adware

Adware comes in various forms, each with its unique characteristics and behaviours:

Browser Hijackers

These notorious culprits hijack your browser settings, changing your homepage or default search engine. Users often find it challenging to revert these changes.

Pop-up Ads

Pop-ups are a common manifestation of malware. They appear suddenly, overlaying your screen with advertisements, sometimes to the point of rendering your browsing experience unbearable.

Ad-injecting Malware

Adware of this type inserts additional ads into web pages you visit, making it appear as if these ads are an integral part of the website’s content.

Spyware

Some malware goes beyond annoying ads and delves into the realm of spying. It clandestinely collects your personal information, potentially compromising your privacy.

Risks and Dangers of Adware

Adware is not merely an inconvenience; it poses real risks and dangers:

Privacy Concerns

Adware’s data collection activities can be invasive, gathering sensitive information about your online behaviour. This data may be misused or sold to third parties, compromising your privacy.

Security Risks

While not all adware is inherently malicious, it can serve as a gateway for more harmful threats to infiltrate your device. Malware can lead to security vulnerabilities, making your system susceptible to malware infections.

Performance Issues

 Adware’s resource-intensive activities can significantly slow down your device, affecting its overall performance. This slowdown can be frustrating and disruptive to your daily activities.

Signs of Adware Infection

Recognizing the signs of adware infection is essential for prompt action:

Increased Number of Ads

If you notice that advertisements have suddenly multiplied while you browse, it’s a clear indicator of malware.

Browser Redirects

Malware can hijack your browser, causing it to redirect you to unexpected websites, often unrelated to your search queries.

Sluggish Performance

A noticeable decrease in your device’s speed and responsiveness may be a result of adware’s resource consumption.

Unwanted Pop-ups

Annoying pop-ups that persistently appear, interrupting your browsing sessions, are a classic symptom of Malware infection.

Prevention and Removal of Adware

Protecting your devices from Malware requires a proactive approach:

Safe Internet Browsing Practices

Exercise caution when downloading and installing free software from the internet. Pay close attention to installation agreements, and avoid clicking on suspicious links or ads.

Using Reliable Antivirus and Anti-Malware Software

Invest in reputable security software that can detect and remove Malware effectively. Regularly update your security software to stay protected against evolving threats.

Removing Adware Manually

For tech-savvy users, manual removal of malware is possible, but it requires a deep understanding of your system and the specific Malware variant.

Resetting Browsers to Default Settings

If your browser is affected, resetting it to its default settings can often eliminate Malware-related changes and disruptions.
