McAfee crashes are usually caused by corrupted McAfee files, driver conflicts after Windows updates, or insufficient system resources. The fix is almost always a repair installation or clean reinstall with MCPR.

Key Points
- McAfee crash immediately on startup: run McAfee repair via Control Panel → Programs
- McAfee crash during scan: reduce scan priority → McAfee → gear icon → Scheduled Scans → set to Low Priority
- Crash after Windows update: repair McAfee first, if still crashing, use MCPR and fresh install
- Insufficient RAM: McAfee needs at least 2GB free RAM during scans — close other programs during a Full Scan
- McAfee and other security software: remove any conflicting security products (only one AV at a time)
- Windows Event Viewer: shows the specific crash error code that can help diagnose the cause
- McAfee Virtual Technician: run this free tool first — it detects and fixes most crash causes automatically
- If MCPR reinstall doesn’t fix crashes: may be a hardware or Windows issue, not McAfee
