VAN 84 means Vanguard detected a security issue at the kernel level on your system. Something is loaded that Vanguard considers a threat — this could be a vulnerable driver, unsigned software, or remnants of cheating tools.
How to fix it:
- Close and uninstall hardware monitoring tools that use kernel drivers: iCUE, NZXT CAM, HWiNFO (when running in kernel/driver mode), MSI Afterburner's RivaTuner
- Update ALL your drivers — especially chipset, network, and storage drivers from your motherboard manufacturer's website
- Uninstall any virtualization software: VMware, VirtualBox, Hyper-V (disable in Windows Features)
- Do a clean boot: press Win+R, type 'msconfig', go to Services tab, check 'Hide all Microsoft services', click 'Disable all', then restart
- Remove old/unused driver software — check Device Manager for any devices with warning icons
- Make sure no cheat engine or memory modification tools are installed (even if not running)
- Run 'sigverif.exe' to check for unsigned drivers that Vanguard might flag
- If clean boot fixes it, re-enable services one at a time to find the culprit
