What Is Adware? Understanding, Removal & Protection Guide

Adware, short for advertisement-supported software, can be a frustrating and sometimes dangerous presence on your devices. Want to get rid of it or protect yourself? WHAT.EDU.VN offers answers and free guidance. Let’s explore adware definition, types, removal tips, and prevention methods, covering potentially unwanted programs, malware infections, and cybersecurity best practices.

1. What is Adware and How Does it Affect You?

Adware is a type of software that displays advertisements on your computer or mobile device. While some adware is legitimate and simply supports free software, other forms can be intrusive, annoying, or even malicious. It sneaks onto your system, hoping you’ll click those ads – whether you mean to or not.

1.1. The Core Definition of Adware

Adware, at its core, is software designed to display advertisements. These ads can appear in various forms, such as pop-up windows, banner ads, or even within the software itself. The primary goal of adware is to generate revenue for its developers by displaying these advertisements to users. However, the way adware operates and its potential impact on users can vary significantly.

1.2. How Adware Infiltrates Your System

Adware typically finds its way onto your computer or mobile device in one of two primary ways:

Bundled Software: Many free software programs or applications include adware as part of their installation package. Users may unknowingly install adware alongside the desired software, often without realizing it until the ads start appearing. This is a common practice used by software developers to monetize their free offerings.
Software Vulnerabilities: In some cases, hackers can exploit vulnerabilities in your software or operating system to inject malware, including adware, into your system. This type of infiltration is more insidious and can occur without the user’s knowledge or consent.

1.3. The Spectrum of Adware: From Nuisance to Threat

Not all adware is created equal. Some forms of adware are relatively harmless, while others can pose a significant threat to your cybersecurity:

Harmless Adware: At the less harmful end of the spectrum, adware can be a mere nuisance. It may display unwanted pop-up ads or change your browser settings, but it doesn’t actively try to harm your system or steal your data.
Harmful Adware: On the more harmful end, adware can be a damaging malware threat. It can track your browsing history, redirect your searches, and even install malicious software on your device. This type of adware can compromise your privacy, slow down your system, and expose you to other online threats.

1.4. Adware’s Financial Motivation

The primary motivation behind adware is financial gain. Adware creators and distributors make money through various methods, including:

Pay-Per-Click (PPC): They get paid each time you click on an ad displayed by the adware.
Pay-Per-View (PPV): They get paid each time an ad is shown to you.
Pay-Per-Install (PPI): They get paid each time bundled software containing adware is installed on a device.
Data Collection: Adware can track your search and browsing history and sell this information to third parties for additional income.

2. Identifying Different Types of Adware

Understanding the different types of adware is crucial for identifying and addressing potential threats. Adware can range from legitimate, ad-supported software to malicious programs that compromise your system’s security.

2.1. Legitimate Adware: A Necessary Evil?

Legitimate adware is software that you willingly download and install, knowing that it contains advertisements. This type of adware allows developers to offset their costs and offer their software for free. Users consent to the ads and software promotions in exchange for the free product.

Consent is Key: The defining characteristic of legitimate adware is that users knowingly and willingly agree to its presence.
Collection of Marketing Information: You might choose to allow legitimate adware to collect marketing information about your browsing habits.
Reputable Developers: Legitimate adware is often created by reputable developers as a valid and legal way to provide customers with a free product.
Personalized Ads: The accompanying personalized ads or sponsored third-party software can sometimes be desirable, offering relevant products or services.

2.2. Potentially Unwanted Applications (PUAs): The Gray Area

Potentially unwanted applications (PUAs), also known as potentially unwanted programs (PUPs), are programs that you might not have chosen to install on your device. These applications often come bundled with other software or are installed without your explicit consent.

Gray Area: PUA adware falls into a gray area, where the extent to which it is malicious or illegal depends on the goals of the software and those who distribute it.
Legal Deceptive Adware PUA: This type of adware may actively make it tricky to opt-out of installing harmless third-party software. Legitimate adware sometimes uses this method, which is legal if the creator has not knowingly included malware-tainted ads or software.
Legal Abusive Adware PUA: This type of adware is designed to bombard you with excessive ads, either within the adware itself or in packaged software via web browser toolbars or other means. While annoying, this is also legal as long as it doesn’t involve malware.
Illegal Malicious Adware PUA: This is the most dangerous type of adware, profiting from malicious third parties who want to distribute malware like spyware, viruses, or other malicious software onto devices. This malware may be intentionally masked within the adware itself, the websites it advertises, or in accompanying software.

2.3. The Bottom Line: “Adware” Often Means Trouble

When people talk about “adware,” they typically refer to programs that abuse ads and open the door for malware. This type of adware can be frustrating regardless of legality and can easily go undetected for a long time. To avoid any invasive or tedious software, you should know what to look for.

3. Recognizing the Signs of an Adware Infection

Detecting an adware infection early is crucial for minimizing its impact on your system and data. Here’s how to identify the telltale signs:

3.1. Computer Adware Infection Symptoms

If your computer is infected with adware, you may experience the following symptoms:

Unexpected Homepage Change: Your web browser’s homepage may change without your consent.
Incorrect Web Page Display: Web pages you visit may not display correctly or may be altered.
Overwhelming Pop-Up Ads: You may be bombarded with pop-up ads, even when you’re not browsing the internet.
Slow Device Performance: Your computer may run slower than usual, and applications may take longer to load.
Device Crashing: Your computer may crash or freeze frequently.
Reduced Internet Speed: Your internet speed may be significantly slower than normal.
Redirected Internet Searches: Your internet searches may be redirected to unfamiliar or unwanted websites.
New Toolbar or Browser Add-On: A new toolbar or browser add-on may appear without your knowledge or consent.

3.2. Mobile Adware Infection Symptoms

On your phone, the signs of an adware infection are similar:

Slow Phone Performance: Your phone may run slower than usual, and apps may take longer to load.
Rapid Battery Drain: Your battery may drain quickly, even when you’re not using your phone.
Unfamiliar Apps: Your phone may have apps that you don’t remember downloading.
Unexplained Data Usage: There may be unexplained data usage and higher than expected phone bills.
Numerous Ad Pop-Ups: You may experience a large number of ad pop-ups, even when you’re not using any apps.

3.3. Aggressive Adware and Rootkits

Some adware is aggressive and embeds itself deep into systems with rootkits to make removal challenging. If you are infected with this type of adware, you’ll need to take extra steps to clean your system.

4. Mobile Adware: A Growing Threat

Adware is not limited to computers; it can also infect mobile devices, including smartphones and tablets. Mobile adware can be particularly insidious, as it can be difficult to detect and remove.

4.1. How Mobile Adware Spreads

Mobile adware often spreads through apps in popular categories like entertainment and gaming. These apps may appear harmless at first glance, but once installed, they can behave maliciously.

4.2. The Spectrum of Mobile Adware

Like computer adware, mobile adware ranges from relatively harmless to far more harmful:

Harmless Mobile Adware: At the harmless end, you may download an app that simply spams you with ads once it has been installed. This can be a nuisance, especially because the ads can appear from outside the app, making it hard to identify the cause.
Harmful Mobile Adware: Far more harmful is ad fraud and ad clicker software. This involves apps surreptitiously downloading executable files and running malicious activities in the background. This can include clicking on ads without users knowing or subscribing users to premium services that they then have to pay for.

5. Adware Removal: Taking Back Control

If you suspect that your computer or mobile device is infected with adware, it’s essential to take immediate action to remove it. Adware removal can fix problems like obnoxious pop-ups and hidden spyware, restoring your system to its normal state.

5.1. The Limitations of Manual Removal

While manual removal of adware is possible, it doesn’t guarantee that you’ll find and remove all the components. Adware can be sneaky and hide itself in various locations on your system.

5.2. The Power of Cybersecurity Software

For a reliable and thorough solution, cybersecurity software is your best bet. These programs are designed to scan your system, detect adware, and remove it automatically.

5.3. Key Steps in Adware Removal

To effectively remove adware, you’ll need to detect and take action on each of the following issues:

Adware: Legitimate ad-supported software may be fine to keep, as long as it operates with your consent. Adware or third-party software becomes a PUA when it was either installed without your knowledge or does things you wouldn’t like it to do.
Adware PUA: Adware and sponsored third-party software can be obnoxious at best and a gateway for actual malware at worst. You’ll likely want to remove these.
Malware Infections: Malicious programs may have already infiltrated your system. You’ll need to remove these to stop the immediate threats to your privacy.

5.4. Choosing the Right Anti-Adware Tool

Installing a product that has “anti-adware” abilities is your first step. Software suites like Kaspersky Internet Security offer system scanning and removal of adware and other threats.

5.5. Activating Adware Detection Settings

Checking that your security software’s adware detection settings are active is your next step. Your security software might not detect and remove adware by default, so you’ll need to enable this feature in the settings.

5.6. Addressing Freeware and Shareware Programs

Many freeware and shareware programs stop displaying adverts as soon as you’ve registered or purchased the program. However, some programs use built-in third-party adware utilities that can remain installed on your computer even after you’ve registered or purchased the program. If you remove the adware component, that may cause the program to malfunction.

5.7. When Adware Detection Isn’t Always Clear-Cut

Since there may be valid reasons why adware is present on your computer, antivirus solutions may not be able to determine whether a specific adware program poses a threat to you.

5.8. Kaspersky’s Approach to Adware

Kaspersky’s products give you the option to detect adware and choose how to react to it:

Option #1: Adware Removal: Kaspersky’s antivirus software will help you get rid of the adware if you suspect that an adware program may be a threat because you didn’t consent to its installation, you don’t know where the program came from, or you have concerns over its safety.
Option #2: Choosing Not to Detect Adware: Kaspersky products let you disable the option to detect these programs or add specific programs to a list of exceptions so that the antivirus engine will not flag this adware as malicious. You might do this if you’re confident that it is a program that you have consented to, you know where the program comes from, or you’ve decided that it is not harming your devices or data.

6. Android Adware Removal: A Step-by-Step Guide

If you’re wondering how to get rid of adware on your Android phone, here’s a step-by-step guide:

Step 1: Start Your Phone in Safe Mode: This will prevent any third-party apps from running, making it easier to identify the culprit.
Step 2: Remove Malicious Device Admin Apps: Adware may grant itself device admin privileges to prevent you from uninstalling it. Remove any suspicious apps from the device admin list.
Step 3: Uninstall the Malicious Apps: Identify and uninstall any apps that you suspect are responsible for the adware.
Step 4: Use Antivirus Software for Android: Install and run a reputable antivirus app to scan your phone for viruses, adware, and other malware.
Step 5: Remove Redirects and Pop-Up Ads from Your Browser: Clear your browser’s cache and data to remove any redirects or pop-up ads.

7. iPhone Adware Removal: A Different Approach

It is rarer for iPhones to have viruses or malware (unless they are jailbroken) because of Apple’s sandboxed nature and the fact that iOS apps don’t communicate with each other. However, you can still turn off ad pop-ups on your iPhone or iPad:

Step 1: Open Chrome on your iPhone or iPad.
Step 2: Tap the three dots, then the Settings icon.
Step 3: Tap Content Settings > Block pop-ups.
Step 4: Turn Block pop-ups off.

8. Protecting Yourself from Adware: Prevention is Key

Cleaning out unwanted adware and other PUAs is a solid start for boosting your cybersecurity. However, the best way to deal with adware is to prevent it from infecting your system in the first place.

8.1. The Importance of Proactive Security

Preventing adware is the best way to avoid having to deal with these issues, especially as new forms of adware emerge all the time. Practicing healthy upkeep of your computer and behaving safely is good for your security as a whole.

8.2. General Cybersecurity Best Practices

In general, you’ll be more protected against all cyber threats, including adware, if you:

Keep All Software Updated: The most recent updates for your apps, system drivers, operating system (OS), and other software have security fixes in them.
Be Cautious, Not Curious: In the digital world, treat anything unknown or unusual as a potential risk.
Watch for the Fine Details: Whether it’s a legitimate program installation or a link in an email, always pay attention to what you’re opening or accepting.
Keep Your Activities Legal: Pirating media and software puts you closer to seedy criminals that take advantage of your desire for “free stuff.”

8.3. Safe Downloading Habits

When you’re downloading free computer software, mobile apps, or browsing the web:

Always Read All Terms and Checkbox Agreements: Before clicking “next” during software installation, read all terms and checkbox agreements carefully.
Only Download Programs from Trusted, Reputable Sources: Download programs only from brands you recognize and trust.
Read Reviews: Before downloading anything, search for user reviews and take note of any negative feedback.
Look Before You Click (or Tap): Be wary of ads that rely on social engineering to trick you into clicking on them.

8.4. Monitoring Your Finances

Keep an eye on your bank statements for any unexpected subscription charges, which could be a sign that you’ve fallen victim to mobile adware.

8.5. The Role of Antivirus Security Software

If you have antivirus security software like Kaspersky Total Security, you already have one of the best solutions to protect against adware. Security software actively guards against malicious or PUA app downloads, scans attachments and links, and blocks pop-ups.
