FAQ

What is the best antivirus software?

Bitdefender Total Security at $90 is the best overall with 100% malware detection, an included VPN, and minimal system impact. Norton 360 Deluxe is best for identity theft protection.

Is free antivirus enough?

Free antivirus like Windows Defender catches most threats but lacks a VPN, identity protection, and multi-device support. For banking and shopping, paid antivirus like Bitdefender or Kaspersky is worth it.

Does antivirus slow down my PC?

Good antivirus has minimal impact. Bitdefender and ESET have the lightest system impact. McAfee and Trend Micro can slow down older PCs during full scans.

Can I run two antivirus programs?

No. Two real-time antivirus programs conflict and slow your PC. The exception is Malwarebytes, which is designed to run alongside another antivirus as a second-opinion scanner.

Is a VPN included with antivirus?

Some suites include a VPN. Norton 360 Deluxe offers an unlimited VPN. Bitdefender includes a VPN limited to 200MB per day, which is enough for light browsing but not streaming.
