WRkrn.sys Blue Screen: How to Fix This System Error

The WRkrn.sys driver is a kernel-mode driver used by Webroot SecureAnywhere, and it may sometimes trigger a Blue Screen of Death (BSoD) error.

However, the fixes are not always complicated. So, in this guide, we have put together some easy-to-follow steps to rid your computer of the blue screen error.

What causes the WRkrn.sys BSoD?

• Corrupted or outdated WRkrn.sys – Outdated drivers are the main culprits for BSoD errors like the one caused by WRkrn.sys.
• Conflict with another driver – There are chances that the WRkrn.sys driver is conflicting with other drivers on your computer.
• Hardware problem – If your computer’s hardware is not working properly, it can cause the driver to fail and trigger the stop code.
• An outdated antivirus – If you use an outdated version of the Webroot antivirus, chances are that associated drivers are outdated and will trigger this issue.

How do I fix a wrkrn.sys BSoD?

Before exploring any complex fixes, we recommend you run a virus scan to ascertain the BSoD is not triggered by malware, restart your computer, and uninstall conflicting apps, which will most likely be other third-party antivirus programs.
