Free Antivirus: The Hidden Costs

The Changing Landscape of Free Antivirus Software

The functionality and integrity of complimentary antivirus programs have diminished over time. What was once a straightforward service is now frequently accompanied by undesirable additions.

Previously, free antivirus software primarily relied on prompting users to purchase premium versions for enhanced protection. However, current practices extend beyond simple advertising.

Bundled Software and Revenue Models

Many free antivirus providers are now incorporating adware, spyware, and unwanted toolbars into their installations. This practice is undertaken to generate revenue quickly.

These companies are leveraging multiple income streams, including advertising displays, user data tracking, and the installation of potentially unwanted programs – often referred to as “junkware.”

Shifting from Upgrades to Direct Monetization

The initial model centered around encouraging users to transition to paid antivirus subscriptions. This has evolved into a more direct monetization strategy.

Contemporary free antivirus businesses now profit from advertising revenue, monitoring user activity, and the surreptitious installation of unnecessary software.

• Adware: Software displaying unwanted advertisements.
• Spyware: Software that secretly monitors user activity.
• Junkware: Unnecessary or unwanted software.

Therefore, users should exercise caution when selecting and installing free antivirus solutions, carefully reviewing installation options to avoid unwanted software.

Profiting from Your Computer: A Closer Look

It’s important to understand the methods antivirus companies employ to generate revenue. These tactics often mirror those used by "freeware" applications, which can burden your system with unwanted software.

Revenue Generation Strategies

Several techniques are utilized to monetize user activity. These practices can impact your browsing experience and potentially compromise your privacy.

• Search Engine Redirection: A common practice involves altering your browser’s default search engine. Antivirus providers then profit from advertising revenue generated by clicks on search results within their customized search platform.
• Homepage Modification: Companies may also attempt to replace your homepage with a different website. This redirection aims to increase traffic to sites that generate income through advertising.
• Toolbars and Their Variants: The installation of unwanted toolbars, such as the Ask toolbar, is frequently bundled with antivirus software. Some companies even rebrand the Ask toolbar under their own name, while still utilizing its core functionality.
• Bundled Software (“Junkware”): Antivirus installers often include additional programs, presented as optional "offers," that are automatically installed unless specifically deselected.
• Data Collection and Tracking: User browsing habits and personal information are often tracked by antivirus companies.

The collected data may be sold to third parties, providing an additional revenue stream. It is crucial to be aware of these practices to protect your online experience.

Comodo Free

Recent reports indicate that downloads from sites like Download.com and others have been observed to include adware that disrupts HTTPS connections, mirroring the issues previously seen with Superfish.

The installation of Comodo Free antivirus software attempts modifications to your web browser’s default search engine, redirecting it to Yahoo!. Furthermore, it packages the GeekBuddy service, which is a paid technical support application.

Additional Comodo products are often included during installation, potentially without explicit user consent. This can involve alterations to your DNS server configurations, directing them to Comodo’s servers.

Installation may also introduce "Chromodo," a Chromium-based web browser developed by Comodo itself.

Security Concerns

The PrivDog software, which is associated with Comodo, was found to possess a significant security vulnerability. This flaw was comparable to the one exploited by Superfish.

Given this history, it is advisable to exercise caution and avoid installing a multitude of software and services originating from Comodo on your computer.

The presence of such bundled software could potentially expose your system to security risks.

Ad-Aware Free: A Closer Look

Lavasoft’s Ad-Aware Free version promotes a “Web Protection” feature designed to “enhance your online browsing security.” This is achieved by altering your browser settings to utilize SecureSearch as both your homepage and default search provider.

However, it’s important to note that this functionality doesn’t represent a genuine security enhancement. It simply redirects your web searches through a branded search engine.

This rebranded search engine, SecureSearch, is actually powered by Yahoo!, which in turn utilizes Bing’s search index.

Understanding the Implications

If you are a user who prefers Bing as your search engine, accessing it directly through the official Bing website is recommended.

You will likely find a more comprehensive and user-friendly experience compared to utilizing Lavasoft’s modified and limited search interface.

SecureSearch essentially provides a rebranded version of a familiar search experience, offering no unique benefits.

The core function is a redirection, not an improvement in search quality or security.

Avira Free Antivirus

During installation, Avira prompts users to install “Avira SafeSearch Plus.” This is essentially a re-branded iteration of the Ask Toolbar.

The toolbar functions by redirecting your search queries through a customized version of Ask.com’s search engine.

Should you prefer not to have the Ask Toolbar installed on your system, it is advisable to also decline the installation of this re-branded variant.

Understanding the Implications

The inclusion of Avira SafeSearch Plus represents a potential unwanted program (PUP) bundled with the antivirus software.

Users should be aware of this during the installation process and carefully review all options presented.

Careful consideration is recommended to avoid unintended software installations.

This practice is common among free antivirus solutions, where additional software is offered to generate revenue.

It’s important to note that while Avira provides robust antivirus protection, the bundled software may not align with all user preferences.

Therefore, a conscious decision should be made regarding the installation of Avira SafeSearch Plus.

ZoneAlarm Free Antivirus + Firewall

ZoneAlarm prompts users to adopt "ZoneAlarm Search" as their preferred homepage and search engine. This also involves the installation of a ZoneAlarm toolbar, which functions as a re-branded iteration of the Ask Toolbar.

Additional Software Offers

The free version of ZoneAlarm actively encourages the adoption of additional software components. Specifically, it pushes users towards changing their browser settings.

These suggested changes include setting ZoneAlarm Search as both the default homepage and search provider. The accompanying toolbar is essentially a customized version of the widely-known Ask Toolbar.

• Browser Hijacking Potential: Users should be aware of the potential for unwanted browser modifications.
• Re-branding: The ZoneAlarm toolbar is not a unique product, but a modified Ask Toolbar.

It’s important to carefully review all installation options and decline any unwanted software offers during the setup process. This ensures a clean installation of the core antivirus and firewall functionality.

Maintaining control over browser settings is crucial for a secure and personalized online experience. Users should exercise caution when prompted to change these settings by any software.

Panda Free Antivirus

During installation, Panda Free Antivirus makes an effort to modify your browser settings. Specifically, it tries to install a browser security toolbar and alter both your default search engine and homepage.

The intended search engine replacement is Yahoo, while the homepage is set to "MyStart," a Yahoo-powered service. It is noteworthy that Panda is transparent in this regard.

Unlike some other free antivirus programs, Panda does not disguise Yahoo as a differently named search provider or homepage.

This practice of bundled software and altered settings is a common tactic among free antivirus solutions.

Users should always pay close attention during the installation process to avoid unwanted changes to their browser configurations.

Panda Free Antivirus’s behavior highlights the importance of carefully reviewing installation options.

Being aware of these potential modifications allows users to maintain control over their browsing experience.

It’s crucial to understand that even “free” software can come with additional, potentially unwanted, components.

Therefore, a vigilant approach during installation is highly recommended.

avast! Free Antivirus

During installation, avast!'s program suite attempts to install supplementary software that users may not require. Previously, we observed offers for Dropbox; however, during our recent testing, the Google Toolbar was presented as an installation option.

Software such as the Google Toolbar and Dropbox represent legitimate applications that some users may find beneficial. This practice positions avast! favorably in comparison to other antivirus solutions. Nevertheless, avast! has exhibited concerning behavior previously, notably with its browser extension interfering with online purchasing activities.

Bundled Software Attempts

The inclusion of potentially unwanted programs during the installation process is a common tactic among free antivirus providers. avast! distinguishes itself by offering generally useful applications alongside its core security software.

Despite this, past instances of intrusive browser extensions demonstrate that avast! is not entirely free from questionable practices. Users should exercise caution and carefully review installation options.

It’s important to note that while these bundled offers aren’t inherently malicious, they can lead to unwanted software cluttering a user’s system. Paying close attention during setup is crucial.

Careful installation is recommended to avoid unintended software additions.

AVG Free

AVG traditionally bundles several potentially unwanted utilities alongside its antivirus software, such as the AVG Security Toolbar, AVG Rewards, AVG Web TuneUp, and SecureSearch.

Consequently, AVG provides detailed guidance on how to remove these additional components.

Interestingly, during our installation of AVG Free 2015, these extra applications were not offered for installation on our test system.

Given AVG’s history of including toolbars and similar add-ons, it remains uncertain whether this represents a lasting shift in their approach or a temporary adjustment.

We continue to exercise caution when evaluating AVG’s free antivirus offering.

Concerns Regarding Bundled Software

• AVG Security Toolbar: A browser extension that can modify web search results.
• AVG Rewards: A program offering incentives for using AVG products.
• AVG Web TuneUp: A tool designed to optimize web browser settings.
• SecureSearch: AVG’s default search engine.

The inclusion of these bundled programs has historically been a point of concern for users seeking a straightforward antivirus solution.

While the recent installation experience was cleaner, vigilance remains advisable.

Bitdefender Antivirus Free Edition

A streamlined, no-cost antivirus solution is provided by Bitdefender. This version is designed without the inclusion of unwanted software or toolbars during installation. Historically, Bitdefender Free has maintained a reputation for avoiding the bundling of potentially unwanted programs.

Despite being a free offering, Bitdefender continues to employ tactics aimed at encouraging users to upgrade to their premium, paid antivirus products.

Key Features and Considerations

The primary benefit of Bitdefender Free is its core antivirus protection. It focuses on delivering essential security without the added features found in the paid versions.

Users should be aware that frequent prompts to upgrade may be presented. These are part of Bitdefender’s business model, designed to convert free users into paying customers.

Important Note: While the free edition provides robust malware detection, it lacks some of the advanced features like a firewall or ransomware protection available in the paid suites.

The absence of bundled software makes Bitdefender Free a reliable choice for users seeking basic, unobtrusive antivirus protection.

It’s a solid option for those who prioritize a clean installation and effective virus scanning, even with the occasional upsell attempt.

Malwarebytes Anti-Malware Free

Malwarebytes provides a valuable tool for computer security, particularly when used alongside other antivirus solutions. It's important to note that the free version does not include real-time protection capabilities.

Unlike some free security programs, Malwarebytes avoids bundling unwanted software during installation. The developers actively promote their premium, more comprehensive product while still offering a functional free scanner.

Manual Scanning and Adware Detection

The free version of Malwarebytes excels at performing manual scans. It effectively identifies and removes a wide range of threats, including adware often installed by other programs.

This makes it a strong complement to a primary antivirus program, such as Microsoft’s Windows Defender or Microsoft Security Essentials.

Limitations as a Standalone Solution

However, it’s crucial to understand that Malwarebytes Free isn’t designed to function as a complete, independent antivirus solution. The absence of real-time scanning is a significant limitation.

Without continuous monitoring, your system remains vulnerable to threats between manual scans. Therefore, pairing it with a program offering real-time protection is highly recommended.

Consider using Malwarebytes as a secondary layer of defense to enhance your overall security posture.

Choosing the Right Antivirus Software

Many antivirus programs, even those considered effective, can be intrusive. Instead of a clean installation, users often encounter frequent pop-up notifications and prompts to install additional software or subscribe to paid services.

Data collection and potential sales of browsing information are also concerns associated with some antivirus solutions.

Truly free antivirus options do exist. Microsoft’s Windows Defender is integrated into Windows 8, 8.1, and 10, and is also available as Microsoft Security Essentials for Windows 7.

This free protection is effectively funded through the cost of Windows licenses.

BitDefender currently provides a robust product experience, free from unwanted additions. While avast! is generally high-quality, it does attempt to install supplementary software.

AVG has historically included unwanted software, though recent tests showed improvement; however, avast! remains the preferable choice among these free alternatives.

For users seeking enhanced protection, paid antivirus solutions are available. Kaspersky and BitDefender consistently achieve higher ratings than many free applications, making them worthwhile investments.

Antivirus companies must generate revenue to sustain their operations. With a large segment of users preferring free antivirus programs and resisting upgrades, these companies are increasingly relying on advertising, software bundling, and user tracking.

Careful consideration is crucial before downloading any antivirus software. Even the free versions from reputable companies may include unwanted software that can negatively impact your computing experience.
