Frequently Asked Questions
Do I really need antivirus in 2025?
Yes. Modern malware spreads through emails, downloads, USB drives, fake apps, phishing links and even legit websites that were hacked. Antivirus protects against ransomware, spyware, keyloggers, data theft and browser hijacking.
Is free antivirus enough?
Free antivirus can block basic threats but cannot defend against ransomware, identity theft, online tracking or phishing attacks. Most free tools also lack firewalls, VPN, data breach alerts and webcam protection.
What antivirus works best for Windows and Mac?
Norton and Bitdefender consistently score highest in malware detection, ransomware blocking, phishing protection and system performance on both Windows and macOS.
Will antivirus slow my computer?
Modern security software is optimized to run quietly in the background. Top antivirus tools use cloud-based scanning and smart resource usage so your device stays fast during gaming, work and streaming.
How do we test antivirus software?
We use real malware samples, ransomware simulations, phishing URLs and performance benchmarks inside a secure sandbox environment. Results are updated regularly.
Do I need antivirus if I already use a VPN?
No. VPN protects your identity and encryption, but does not stop malware. Antivirus and VPN together create complete protection against hackers, trackers, phishing and ransomware.
Can antivirus detect hidden spyware and stalkerware?
Yes. Premium security suites detect hidden tracking apps, keyloggers, remote access tools and malicious browser plugins designed to spy on users.
