How to Choose the Best Antivirus Software for 2025: The digital landscape is more perilous than ever, with over 300,000 new malware variants emerging daily, including viruses, ransomware, and phishing attacks. Antivirus software is essential for protecting devices Windows, macOS, Android, iOS, and more from these threats, safeguarding personal data, financial information, and system integrity.
With countless options available, choosing the right antivirus software requires evaluating protection levels, performance impact, features, and cost.
Why Antivirus Software Matters in 2025
The cybersecurity landscape has evolved rapidly, driven by AI-powered malware, sophisticated phishing schemes, and ransomware that can lock devices until a ransom is paid. According to AV-TEST, malware attacks are increasing by 30% annually, costing businesses and individuals billions. Built-in protections like Microsoft Defender are insufficient against advanced threats, lacking real-time protection, phishing defenses, or cross-platform support. Premium antivirus solutions offer comprehensive security, including firewalls, VPNs, and identity theft protection, making them critical for users engaging in online banking, gaming, or remote work. Here’s how to choose the best antivirus software for your needs in 2025.
1. Prioritize Malware Protection
Effective antivirus software must excel at detecting and neutralizing malware, including viruses, trojans, ransomware, and spyware. Look for products with near-perfect detection rates (99% or higher) in tests by independent labs like AV-TEST and AV-Comparatives. Norton 360 Deluxe and Bitdefender Total Security consistently score 100% in malware detection, with Norton achieving top marks in AV-TEST’s April 2025 report for protection, performance, and usability. These solutions use AI-driven heuristics to identify zero-day threats, ensuring robust defense against new malware.
2. Evaluate Real-Time Protection
Real-time protection prevents malware from executing before it harms your device. Unlike free antivirus tools, which often require manual scans, premium options like TotalAV and McAfee+ Premium monitor files, downloads, and web activity in real time. TotalAV’s full scan detected 100% of malware samples in 2025 tests, while McAfee’s real-time protection blocked EICAR test files instantly. Ensure your antivirus includes active scanning for email attachments, USB drives, and web downloads to catch threats as they emerge.
3. Consider Performance Impact
Antivirus software should protect without slowing your device. Modern solutions like Bitdefender Antivirus Plus and Surfshark Antivirus are lightweight, with minimal CPU usage (under 10% during scans). In contrast, older or poorly optimized software can cause lag, especially during full system scans. Sophos Home Premium, for example, adds multiple processes but maintains performance, scoring 100% in SE Labs’ December 2024 tests. Test free versions or trials to ensure compatibility with your device, especially for gaming or resource-intensive tasks.
4. Look for Cross-Platform Compatibility
In 2025, users often own multiple devices—PCs, Macs, smartphones, and tablets. Choose antivirus software that supports all major platforms without extra costs. Norton 360 Deluxe covers Windows, macOS, Android, and iOS for up to five devices at $50 for the first year. McAfee+ Premium supports unlimited devices, ideal for families, with seamless apps for ChromeOS as well. Cross-platform support ensures consistent protection across your digital ecosystem, critical for remote workers or households.
5. Assess Additional Features
Beyond malware protection, top antivirus suites offer extras like VPNs, password managers, and identity theft protection. Norton 360 Deluxe includes a VPN with AES-256 encryption, 50GB cloud backup, and dark web monitoring, making it a comprehensive security suite. Bitdefender Total Security adds a performance optimizer and up to $2 million in identity theft insurance for U.S. users. TotalAV Total Security bundles a password manager and VPN for $49/year, offering value for budget-conscious users. Prioritize features that align with your needs, such as parental controls for families or anti-phishing for frequent online shoppers.
6. Check Phishing and Web Protection
Phishing attacks, which trick users into sharing sensitive data, are a top threat in 2025, accounting for 30% of data breaches. Antivirus software like Avast Premium and Trend Micro excels at blocking malicious URLs and phishing emails, with Trend Micro’s PayGuard tool securing online banking. Browser extensions, such as Avira’s, block trackers and malicious sites, enhancing web safety. Ensure your antivirus includes robust anti-phishing and safe browsing tools, especially if you frequent less-secure websites or use public Wi-Fi.
7. Verify Ease of Use
A user-friendly interface is crucial, especially for non-tech-savvy users. TotalAV offers an intuitive dashboard, earning praise for accessibility in 2025 reviews. McAfee+ Premium simplifies setup with automatic scans, ideal for families. Test free versions to assess usability, as complex interfaces can lead to underutilization. Look for software with clear dashboards, quick-scan options, and responsive customer support via live chat or email, as seen with Norton and Bitdefender.
8. Compare Pricing and Value
Antivirus pricing varies widely, from free options like Avira Free Antivirus to premium suites like Norton 360 Deluxe ($50/year for five devices). TotalAV starts at $19/year for basic protection, while McAfee+ Premium costs $50 for the first year for unlimited devices. Free versions often lack real-time protection or advanced features, making paid plans better for comprehensive security. Check for discounts (e.g., Norton’s $50 first-year deal) and money-back guarantees (TotalAV’s 30-day refund) to test value risk-free.
9. Review Independent Test Results
Independent labs like AV-TEST, AV-Comparatives, and SE Labs provide objective benchmarks. In April 2025, Norton 360 and Bitdefender Total Security scored 6/6 in protection, performance, and usability, while TotalAV earned perfect marks for malware detection. McAfee+ Premium scored high but had occasional false positives in AV-Comparatives’ March 2025 tests. Cross-reference these results to ensure your choice aligns with real-world performance, avoiding marketing hype.
10. Consider Customer Support and Updates
Reliable support and frequent updates are vital for staying ahead of new threats. Norton and Bitdefender offer 24/7 live chat and email support, with regular updates to combat emerging malware. TotalAV provides email support and an online knowledge base, though response times can vary. Check for automatic updates and subscription-based support, as outdated software leaves devices vulnerable. Following brands on platforms like X (e.g., @NortonSupport) can provide real-time updates on new features or threats.
