Key Points
- Real-Time Scanning: must be ON (PC Security > Real-Time Scanning)
- Firewall: ensure enabled at PC Security > Firewall
- Auto-Updates: set to ON so McAfee always has the latest threat database
- Scheduled Scans: set Full Scan weekly at a time you’re not using your PC (e.g. 2:00 AM)
- McAfee WebAdvisor: ensure the browser extension is enabled in Chrome/Edge/Firefox
- VPN (Safe Connect): set to auto-connect on public Wi-Fi networks
- Identity Monitoring: check McAfee has your email address in Protection Centre > Identity
- Firewall Internet Access: leave at ‘Allow All’ unless you need strict controls — over-restriction causes program errors
- Scanning Exclusions: only exclude folders you are 100% certain are safe
