Frequently Asked Questions (FAQs)

Do I really need antivirus software in 2025?
Yes. While operating systems like Windows and macOS have improved their built-in security, they still don’t offer the comprehensive, multi-layered protection of a dedicated antivirus suite. Cyber threats are constantly evolving, and a premium antivirus provides crucial defenses against ransomware, phishing, zero-day attacks, and more.

Can Macs get viruses?
Absolutely. The myth that Macs are immune to malware is outdated. As Macs have become more popular, they have become a bigger target for cybercriminals. Dedicated Mac antivirus software is essential for protecting your Apple devices from threats.

Will antivirus software slow down my computer?
Modern antivirus software is designed to be lightweight and efficient. While a full system scan might use some resources, top providers like Bitdefender and Norton have a minimal impact on day-to-day performance. Most run silently in the background, protecting you without you even noticing.

Is free antivirus good enough?
Free antivirus programs offer basic protection, which is better than nothing. However, they typically lack advanced features like ransomware protection, firewalls, secure VPNs, and parental controls. For comprehensive security and peace of mind, a paid subscription is highly recommended.

Which is better: Norton or McAfee?
Both are excellent choices, but they cater to different needs. Norton 360 often has a slight edge in malware detection and feature breadth, making it our top overall pick. McAfee, however, is the better value if you need to protect a large number of devices, thanks to its unlimited coverage plans.
