McAfee is designed to protect without impacting performance, but some users report slowdowns. In most cases the issue is a configuration problem, not McAfee itself. This guide helps UK users get McAfee running quietly in the background without affecting PC speed.

Key Points
- Check scheduled scans — move them to overnight or low-usage hours
- Exclude trusted folders (Documents, Photos) from real-time scanning
- Disable the McAfee WebAdvisor browser extension if not needed
- Ensure McAfee is updated — old versions can cause high CPU usage
- Use McAfee’s PC Boost feature to optimise background processes
- Increase virtual memory if your PC has less than 4 GB RAM
- Check for malware — slowdowns are sometimes caused by infections, not McAfee
- Call +44-800-066-8910 if performance issues persist after optimisation
