If you plan to use the McAfee Virus Removal Service, your Windows PC must have a minimum of 4 GB of RAM (not the standard 2 GB) to support the live technician session tools that run alongside McAfee during the removal process.

If your Windows PC is running low on the required 1.3 GB of free disk space, use the built-in McAfee PC Optimizer tool to clean up junk files, unnecessary temporary data, and browser cache before beginning the McAfee installation. This not only frees up space but can also improve overall system performance.
