Multiple security products load low-level drivers at the same time, which easily leads to mutual blocking, freezes or even blue screens. Keep just one.
Typical symptoms
Slow boot, frozen programs, broken features or occasional blue screens can all indicate driver conflicts.
- Noticeably slower boot
- A feature stops working
- Random freezes or blue screens
What to do
Keep one main protection product and fully uninstall the others, then reboot to confirm the drivers are gone.
- Keep only one security product
- Clean up with the official removal tool
- Reboot and verify
FAQ
Can I keep a firewall and an antivirus together?
Yes, but avoid running two products that both provide full behavior-based protection.
A leftover driver remains after uninstalling.
Use the vendor's official cleanup tool, or remove the driver files manually in safe mode.
