Detailed Review
Panda Internet Security Review: Updated for 2025
Panda Dome offers versatile antivirus packages with flexible pricing, making it an attractive option for customizable protection. It combines strong malware detection, user-friendly tools, and valuable features, though it has drawbacks like false positives and limited VPN functionality.
Anti-Malware Protection
Panda achieves a solid 99.9% in real-world protection tests, effectively combating malware, ransomware, and zero-day threats. Its use of AI, big data, and machine learning ensures robust defenses against known and emerging threats.
However, its higher rate of false positives can be inconvenient, particularly for users of niche applications. Panda’s performance is evaluated by AV-Comparatives and independent testing, as it does not participate in AV-Test’s reviews.
Firewall
Panda’s firewall offers reliable protection by filtering inbound and outbound traffic, automatically setting security levels for applications, and enabling advanced users to customize app-specific rules. This flexibility makes it suitable for both beginners and experts.
VPN
Panda’s free VPN is limited to 150 MB daily, restricting its use to basic browsing or light streaming. Powered by Aura’s technology (AES-256 encryption and HydraVPN protocol), it provides fast, secure, and private connections without logging user activity.
However, advanced features like a kill switch are absent. Unlimited VPN is only available with the €60/$67 Premium plan, making it pricier than standalone VPNs with broader functionality.
Password Manager
Panda’s password manager excels with secure password generation, storage, and auto-fill, supported by two-factor authentication and biometric login. Its browser extensions for Chrome and Firefox align well with its mobile apps, offering a seamless experience across platforms.
Pricing & Packages

Is Panda the Best Internet Security Software of 2025?
Panda Dome is a top antivirus solution in 2025, offering excellent malware detection, flexible plans, and useful extras like its password manager. However, its higher rate of false positives and a relatively expensive, limited VPN are notable downsides.
For Windows users, Panda provides comprehensive security at competitive prices. But for better Mac or mobile protection or a cost-effective VPN, Norton 360 offers a more integrated alternative with a cheaper unlimited VPN.
Panda’s 30-day money-back guarantee allows users to try its plans risk-free and determine if it meets their needs.

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.

Price comparison
Price matters. So, we compared the second-year prices in the U.S. for each software, rounding up for simplicity (e.g., $99.99 becomes $100). Note that some brands lack key features, affecting their overall value.
To make it a fair comparison, we looked at what it would cost us, to protect a single Windows PC with the most essential features:
- Anti-malware
- Anti-phishing (web protection)
- Firewall
- Password manager
- Unlimited VPN (no data limit).
Prices vary outside the U.S., so check the brands’ websites for your local pricing.
User reviews
We’ve compared the user reviews of all antivirus brands. We’ve used the scores and review count of TrustPilot, a leading user review platform.
We consider scores above 4.0 very good. Lower scores indicate that the brand might have a poor product or customer service. McAfee’s scores, for instance, are worrying.

- Identity Theft Protection: Monitors your personal information for signs of identity theft, alerting you if your data is exposed or misused.
- Parental Controls: Allows parents to block inappropriate content, set screen time limits, and monitor children’s online activity to keep them safe.
In short, internet security software is a must-have in today’s connected world, offering essential protection against a wide range of online threats.
What cyber threats can antivirus protect you from?
Internet security software shields you from a wide variety of malware threats, including:
- Adware: Unwanted software that displays intrusive ads and can track your browsing habits.
- PUPs (Potentially Unwanted Programs): Programs that may not be malicious but can slow down your system or compromise your privacy.
- Ransomware: Malicious software that locks your files or device until you pay a ransom to regain access.
- Rootkits: Stealthy malware designed to hide in your system and allow hackers to control your computer remotely.
- Spyware: Software that secretly collects your personal information and tracks your online activities.
- Trojans: Malware disguised as legitimate software that opens a backdoor for hackers to access your system.
- Viruses: Programs that can replicate themselves and spread across devices, causing damage or data loss.
- Worms: Self-replicating malware that spreads through networks, often causing widespread disruption.
In addition to malware protection, modern internet security suites, with tools like anti-phishing, a firewall, a password manager, a VPN, identity theft protection, and parental controls, defend against a wide range of cyber threats beyond just malware.
What cyber threats can’t antivirus protect you from?
While internet security software is powerful, it can’t protect you from every type of cyber threat.
- Social engineering attacks: These involve tricking people into giving away sensitive information (like phishing scams or phone calls pretending to be from trusted sources). Since these attacks target human behavior, no antivirus can fully defend against them—users must stay cautious and informed.
- Zero-day attacks: These are vulnerabilities that hackers exploit before developers can create a fix. While antivirus software can detect many threats, it may not catch every zero-day attack immediately, as these are often unknown at the time of the attack.
Staying alert and practicing good online habits are essential for complete protection.
How will AI shape cybercrime in 2025?
In 2025, AI and Large Language Models (LLMs) will transform cybercrime, making attacks more sophisticated and harder to detect:
- AI-Enhanced Phishing and Social Engineering: Cybercriminals will craft highly convincing, personalized phishing messages using AI and LLMs, increasing the likelihood of users divulging sensitive information.
- Automated Malware and Attack Strategies: AI will enhance malware by automating and adapting attacks based on real-time feedback from security tools, improving effectiveness.
- Deepfake Impersonation: AI-powered deepfake technology will enable realistic voice and video impersonations, amplifying fraud, identity theft, and social engineering.
- AI-Powered Vulnerability Scanning: Hackers will leverage AI to quickly identify and exploit system vulnerabilities, making attacks faster and more precise.
- LLMs for Malicious Code: LLMs will simplify the creation and refinement of malicious code, empowering even less-skilled attackers to develop sophisticated malware.
Consumers and organizations will need advanced, AI-driven defense systems to counter these evolving threats.
