Antivirus FAQ
Quick answers to common questions about antivirus software.
Do I still need antivirus in 2026?
Yes, for most users. Built-in tools like Windows Defender provide a solid baseline, but dedicated antivirus adds layers like ransomware protection, identity monitoring, and phishing filters that go beyond basic OS security.
Is free antivirus good enough?
Free antivirus can cover basic malware scanning, but paid plans usually add real-time protection, firewalls, identity monitoring, and support across multiple devices. See our free vs paid guide for a full comparison.
Will antivirus slow down my computer?
Modern antivirus software is much lighter than older versions. Reputable providers like Norton and McAfee are designed to run quietly in the background with minimal impact on everyday tasks.
Can I use antivirus and a VPN together?
Yes. Antivirus and VPNs solve different problems. Antivirus protects your device from malware; a VPN encrypts your internet connection. Many people use both together.
What is the difference between antivirus and internet security suites?
Antivirus focuses on detecting and removing malware. Internet security suites bundle antivirus with extras like firewalls, password managers, VPN access, and identity monitoring.
Should Mac users install antivirus?
Macs are not immune to malware. While macOS includes built-in protections, dedicated Mac antivirus adds an extra layer against phishing, ransomware, and cross-platform threats.
