Its 96.2% malware detection rate handles common threats well. However, if you engage in high-risk activities (banking, cryptocurrency trading, accessing untrusted sites), Norton's 99.9% detection rate and additional features like VPN and dark web monitoring offer stronger protection."},{"question":"How much does Norton slow down your computer?","answer":"Norton's full system scans consume 8-12% CPU and take 45-60 minutes on average systems, noticeably impacting performance during scanning. Windows Defender uses only 2-4% CPU with 30-40 minute scans. However, Norton offers quick scan options (5-10 minutes) and scheduled scans at non-peak hours to minimize disruption."},{"question":"What extra features does Norton offer that Windows Defender doesn't?","answer":"Norton 360 includes a VPN with unlimited data, password manager, dark web monitoring (alerts you if your email/passwords appear on the dark web), and advanced behavioral threat analysis.
