Norton’s desktop app isn’t the most intuitive software to use, and mobile users need to download 4 separate apps to get full security on their devices. Norton is very good, but it isn’t perfect. Norton’s anti-malware engine uses machine learning, advanced heuristics, and a consistently updated malware directory to identify malware - from viruses and trojans to advanced malware like ransomware and cryptojackers. During my testing, Norton’s full scan and real-time protection were both able to detect every single malware file I tried to download, with minimal system slowdown and no false positives. Overall, Norton 360 is my favorite antivirus in 2021 - it’s got a powerful anti-malware engine, a wide range of internet security tools, an intuitive online dashboard, and good customer support, all for a better price than most competitors.
