Norton AntiVirus Plus review

Norton AntiVirus Plus is the paid option for people who want more than a free scanner on a Windows 7 PC. Norton's requirements list Microsoft Windows 7 in all versions with Service Pack 1 or later, alongside Windows 8, 8.1, 10 and 11, but not XP or Vista. The plan covers 1 Windows PC or Mac with real-time protection against ransomware, viruses, spyware and malware. It adds Smart Firewall, which monitors and blocks suspicious network traffic, a Password Manager that syncs across Windows, iOS and Android, and 2 GB of cloud backup for important files, a sensible safety net on an old drive that could fail. The 100% Virus Protection Promise refunds you if Norton's experts cannot remove a virus. The first year costs $29.99 and renews at $59.99 per year, with a 60-day money-back guarantee. Value drops after year one, and the single-device limit makes it a poor fit for a house of old PCs.
