Norton 360 Anti-Adware Review: Updated for 2025

Norton continues to lead in security software, extending its robust protection to adware in 2025. Our in-depth testing confirms its effectiveness across operating systems.

Anti-Adware and Malware Protection

Norton 360 excels in detecting and neutralizing adware and malware. Its SONAR real-time scanning engine leverages behavioral analysis and machine learning to identify threats beyond known malware definitions. In testing, Norton successfully blocked all 1,200 simulated threats and achieved a perfect 100% protection score in 10 consecutive AV-Test assessments.

How SONAR Works

SONAR’s heuristic approach identifies adware by analyzing suspicious behavior, such as intrusive ads, browser setting modifications, and unwanted toolbar installations, stopping threats before infection.

Smart Firewall

Norton’s Smart Firewall provides two-way protection, monitoring both incoming and outgoing network traffic. It prevents unauthorized connections, blocks suspicious outgoing traffic, and shields unused ports from cybercriminals—a notable improvement over Windows’ one-way firewall.

VPN: Enhanced Privacy and Ad-Tracker Blocking

Norton’s unlimited VPN encrypts traffic, blocks ad trackers, and protects privacy. It uses AES-256 encryption, OpenVPN protocols, and features a kill switch, split tunneling, and unlimited data.

Password Manager: Safeguarding Credentials

Norton’s password manager securely stores and autofills credentials, mitigating risks of adware-related session hijacking. Biometric authentication adds an extra layer of security.

Pricing and Packages

Norton offers various tiers, combining anti-adware tools with broader security features:

  • Norton Antivirus Plus (€15/$20): Essential antivirus, firewall, and password manager for 1 PC/Mac.
  • Norton 360 Standard (€30/$40): Includes VPN and dark web monitoring for 1 (EU) or 3 (US) devices.

  • Norton 360 Select + LifeLock ($99 US): LifeLock identity protection for 10 devices.

(Note: In some regions, Norton 360 Advanced is branded as Norton 360 Premium without identity theft protection.)

Bonus Features

Additional tools enhance Norton’s value:

  • Web Protection: Blocks malicious sites to prevent adware downloads.
  • Cloud Backup: Secure cloud storage for important files.
  • Parental Controls: Manage children’s online activity.
  • Privacy Monitor: Scans for personal data on broker sites.
  • Webcam Protection: Prevents unauthorized camera access.

Detailed Review

Avast Anti-Adware Review: Updated for 2025

Avast remains a leading antivirus and anti-adware solution in 2025. After testing Avast One, we found it to be a reliable, feature-rich platform for Windows, Mac, Android, and iOS, although it has limitations compared to top-tier competitors.

Anti-Adware and Malware Protection

Avast excels in malware detection and removal, identifying all 1,200 malware samples in our tests, including adware often hidden in software bundles or malicious websites. Full system scans averaged 54 minutes, balancing speed and thoroughness. Real-time protection effectively blocked adware installations, including encrypted downloads, though free users may find frequent upsell prompts distracting.

Adware Defense Mechanism

Avast’s heuristic scanning engine detects suspicious behaviors like unauthorized browser changes or toolbar installations. While effective, the free version offers limited customization, which may not meet the needs of advanced users.

Firewall

The included firewall allows users to monitor and block network traffic. It’s user-friendly for novices and customizable for experienced users, though some features are less robust than competitors.

VPN (Virtual Private Network)

Avast One Essential includes a free VPN with 5GB of weekly data—generous for a free plan. Paid plans offer Avast’s unlimited VPN access, featuring AES-256 encryption, OpenVPN protocol, P2P support, and a no-logs policy.

System Cleanup and Utility Tools

Avast provides tools to boost system performance and security:

  • Browser Cleanup: Removes cookies, cache, and unwanted extensions.
  • Software Updater: Keeps applications up-to-date to reduce vulnerabilities.
  • Password Protection: Shields against keyloggers, though it isn’t a full password manager.
  • Ransomware Shield: Blocks unauthorized encryption of critical files.
  • Email Security: Guards against phishing and malicious attachments.
    Many features are premium-only, but tools like Browser Cleanup are especially effective for adware prevention.

Pricing and Plans

  • Avast One Essential (Free): Malware and adware protection, 5GB/week VPN, and basic cleanup.
  • Avast One Individual ($50/year): Adds unlimited VPN, advanced firewall, and full system cleanup.
  • Avast One Family ($70/year): Covers up to 6 devices with all Individual features.
    All paid plans include a 30-day money-back guarantee.

Is Avast the Best Anti-Adware Software of 2025?

Avast offers excellent malware protection, privacy tools, and system utilities, making it a top contender. However, the lack of a password manager and aggressive upselling may deter some users. Alternatives like Norton 360 offer a more comprehensive package. Nonetheless, Avast’s 30-day refund policy makes it worth trying.

Anti-Adware and Malware Protection

TotalAV leverages Avira’s antivirus engine to deliver excellent adware and malware detection. In tests involving over 1,200 samples, it achieved a 99.8% detection rate, effectively blocking adware from bundled software and browser extensions.

Multiple scan options—Quick, System, Smart, and Custom—ensure flexibility. A full System Scan took about an hour with minimal system impact. Real-time protection was also effective, preventing adware and malicious downloads before they caused damage.

Adware Prevention Mechanism

TotalAV detects adware by analyzing file behavior and network traffic, enabling it to block adware that modifies browser settings or displays unwanted ads. It also prevents potentially unwanted programs (PUPs), a common vector for adware.

VPN: Safe Browsing and Ad-Tracker Blocking

TotalVPN enhances its anti-adware suite with 48 server locations and solid speeds for browsing, streaming, and P2P sharing. The VPN successfully blocked ad trackers during tests, helping prevent targeted ads.

Bitdefender continues to excel in 2025 as a leader in malware and adware protection. Renowned for its lightweight design and robust security, it provides comprehensive defense against threats like adware, malware, spyware, and ransomware.

Anti-Adware and Malware Protection

Bitdefender’s malware detection is unmatched, achieving a 100% success rate in tests. It neutralizes threats, including those that infiltrate via downloads or browser extensions, using its Advanced Threat Defense technology. This tool monitors app behavior in real time, detecting anomalies such as code injection—often employed by adware—and blocking suspicious actions before they compromise your system.

Firewall

The built-in firewall enhances security by managing inbound and outbound connections, ensuring no unauthorized traffic occurs. It also prevents adware from exploiting vulnerabilities through port scans or open ports.

VPN: Limited Free Version, Strong Premium Option

Bitdefender includes a free VPN, but its 200 MB daily limit only supports basic browsing. For unlimited use, Bitdefender’s Premium VPN (available separately or in the Premium Security package) offers AES-256 encryption, HydraVPN protocols, and features like a kill switch and split tunneling. This robust solution supports streaming and P2P file sharing.

Password Manager

A standalone purchase or part of the Premium Security package, Bitdefender’s password manager uses AES-256 encryption and supports auto-fill and two-factor authentication (2FA). While its absence in basic plans is a drawback, it remains a secure choice for protecting login credentials.

Pricing and Plans

Bitdefender’s pricing is competitive, with premium features bundled in higher-tier plans:

A Free Edition is available but offers limited features, slightly outperforming Microsoft Defender.

Bonus Features

Anti-Adware and Malware Protection

McAfee has consistently earned a 100% anti-malware detection score from AV-Test since 2020. It reliably detects and removes malware and adware, including hidden threats like bundled software or malicious browser extensions.

Adware Defense Mechanisms

Despite these drawbacks, the VPN complements McAfee’s security suite well.

Panda Dome Anti-Adware Review: Updated for 2025

Panda Dome remains a standout choice in 2025, offering flexible pricing, a user-friendly interface, and robust anti-malware features. Its internet security suite excels in combating adware, making it ideal for users seeking protection from unwanted software and browser hijackers. While it performs exceptionally well on Windows, its non-Windows capabilities have room for improvement.

Anti-Adware and Malware Protection

Panda Dome boasts a 99.9% detection rate in real-world protection tests, effectively blocking malware and adware. In our tests, it stopped all adware attempts, preventing unwanted installations and system changes. However, it does have a higher false positive rate than competitors, occasionally misclassifying harmless software as threats.

Panda employs big data, AI, and machine learning to scan apps and files, identifying both known and emerging threats like zero-day malware and ransomware. While highly effective, the higher false positive rate may inconvenience some users.

Adware Handling

Panda’s heuristic scanning detects uncataloged adware by analyzing behavior patterns, blocking applications that display suspicious traits such as modifying browser settings or adding toolbars.

Firewall

Panda’s two-way firewall filters inbound and outbound traffic, automatically assigning app permissions based on risk level while allowing user customization. Though effective at blocking unauthorized connections, it lacks advanced features like port cloaking found in competitors like Norton.

VPN: Limited for Free Users

Panda’s free VPN, included in all packages, has a restrictive 150 MB daily data limit. The unlimited VPN in the Dome Premium package offers faster speeds and AES-256 encryption but lacks advanced features like a kill switch and split tunneling. Its high cost may deter users seeking comprehensive VPN functionality.

Password Manager

Panda’s password manager simplifies generating, storing, and auto-filling passwords on major platforms, including Android and iOS. Supporting two-factor authentication (2FA) and biometric login, it enhances security and adds significant value to the Dome Complete and Premium packages.

Pricing and Packages

Panda offers flexible plans with scalable device coverage:

  • Dome Essential (€17 / $24): Antivirus and firewall.
  • Dome Advanced (€23 / $28): Adds anti-phishing and parental controls.
  • Dome Complete (€35 / $43): Includes a password manager and system optimizer.
  • Dome Premium (€60 / $67): Adds unlimited VPN and update manager.

Each plan can secure unlimited devices, making it ideal for families.

Bonus Features

Panda Dome includes several extras to enhance its value:

  • Safe Browsing: Blocks malicious URLs and phishing sites.
  • Dark Web Scanner: Alerts you if your data is compromised.
  • PC Cleanup: Removes adware-related clutter.
  • Wi-Fi Protection: Analyzes and improves network security.
  • Anti-Theft: Locates and locks lost or stolen PCs.
  • File Encryptor/Shredder: Secures sensitive files and deletes them permanently.
  • USB Protection: Scans external drives for malware.

Is Panda the Best Anti-Adware Software of 2025?

Panda Dome delivers excellent adware and malware protection with a user-friendly password manager and flexible pricing. It’s particularly suited for Windows users seeking an affordable, feature-rich security suite. However, its VPN limitations, false positives, and lack of advanced features may deter users on other platforms.

For those seeking a comprehensive solution with better VPN functionality and advanced features, Norton 360 may be a stronger choice. Still, Panda Dome is a great option for cost-effective Windows protection, backed by a 30-day money-back guarantee.

Test score comparison

We conduct in-house anti-malware tests and review the results from AV-Test, a German lab renowned for its objective evaluations. Below is the average of the last 10 AV-Test results for Windows. Their scoring criteria are:

  • Protection (1-6): Effectiveness in blocking malware.
  • Performance (1-6): Impact on system speed.
  • Usability (1-6): Frequency of errors like false alarms.

We calculate a final score using this formula:

Final Score = 60% Protection + 20% Performance + 20% Usability.

While these results influence our choice of the best antivirus for Windows 11, other factors like privacy and identity protection also play a key role. For a similar analysis for Android or macOS, visit our other comparisons:

Note: Brands not listed in the table either do not participate in AV-Test trials or are tested too infrequently, such as Surfshark Antivirus.

Common questions about antivirus software

How does anti-adware software work?

Anti-adware software uses several methods to detect and eliminate malware:

  • Signature-based detection: Compares files and programs against a database of known malware.
  • Heuristic analysis: Examines behavior patterns to identify potential threats not yet in the database.
  • Behavioral detection: Monitors program activity for suspicious behavior, such as unauthorized system changes, and blocks potential threats.
  • Real-time monitoring: Continuously checks for suspicious activity and blocks threats before they harm your system.
  • Machine learning and AI: Leverages artificial intelligence to analyze large datasets, detecting emerging threats through pattern recognition.

For more, read our blog post on what antivirus software is.

What other features does anti-adware have?

Modern anti-adware programs offer more than basic malware protection, incorporating essential features like:

    • Anti-phishing: Identifies and blocks fake websites or emails designed to steal your personal information.
    • Firewall: Monitors incoming and outgoing network traffic, blocking unauthorized access.
    • Password manager: Safely stores and generates strong passwords for your online accounts.
    • VPN (Virtual Private Network): Encrypts your internet connection to protect your data and ensure privacy online.
    • Identity theft protection: Monitors your personal information online and alerts you if your data is at risk.
    • Parental controls: Allows you to manage and restrict content your children can access online.

    Modern anti-adware software goes beyond just adware protection to provide a comprehensive security solution for your device and data.

    What cyber threats can anti-adware protect you from?

    Anti-adware software can protect you from a variety of malware threats, including:

    • Adware: Unwanted programs that bombard you with ads and track your browsing habits.
    • PUPs (Potentially Unwanted Programs): Software that may not be harmful but is often bundled with other downloads and can slow down your system or compromise privacy.
    • Ransomware: Malware that locks your files or system until you pay a ransom to the attacker.
    • Rootkits: Malicious software designed to hide deep in your system, giving hackers control over your device.
    • Spyware: Software that secretly monitors your activity, often stealing sensitive information like passwords.
    • Trojans: Malicious programs disguised as legitimate software, used to gain unauthorized access to your system.
    • Viruses: Malware that replicates itself by infecting other files, often leading to system damage or data loss.
    • Worms: Malware that spreads across networks without needing to attach to other programs, potentially disrupting entire systems.

    Thanks to added tools like anti-phishing, a firewall, a password manager, a VPN, identity theft protection, and parental controls, modern antivirus suites can protect users from a wide range of cyber threats beyond just malware.

    What cyber threats can’t anti-adware protect you from?

    Anti-adware software cannot protect you from social engineering attacks, where hackers manipulate or trick you into sharing personal information or clicking on malicious links. These rely on human error rather than software vulnerabilities.

    Additionally, anti-adware is not guaranteed to protect against every zero-day attack—new, undiscovered threats that exploit vulnerabilities before a security update can be released. While advanced detection methods can help, there’s no foolproof defense against all zero-day exploits.

    Is the built-in security software good enough?

    The built-in security programs in Windows 11 and macOS, like Windows Defender and XProtect, are highly capable of protecting against malware and basic cyber threats. However, they often lack important additional security features that enhance your overall protection, such as:

    • Password manager: Stores and generates strong passwords for better online account security.
    • VPN (Virtual Private Network): Encrypts your internet connection to protect your privacy and data online.
    • Identity theft protection: Monitors for signs of identity fraud and alerts you if your personal data is compromised.
    • Parental controls: Allows you to manage and restrict content your children can access online.

    While built-in software is a solid baseline, it may not offer the comprehensive protection that modern users often need.

    How will AI shape adware in 2025?

    AI and LLMs will enable adware to become more intelligent and evasive in 2025. Attackers could use these technologies to create more convincing phishing ads and design adware that mimics human behavior, making it harder for standard filters to detect. LLMs could also help adware disguise itself as harmless or legitimate software, further increasing the risk of users unknowingly installing it.
