Kaspersky — Kaspersky filter driver
When blamed in a crash: Very likely the true cause
What to do
Kaspersky's kernel filter.
- Update Kaspersky to the newest version.
- If crashes persist, remove it with Kaspersky's official removal tool (kavremover), reboot, and reinstall fresh — or stay on Defender.
Official download (the vendor's own site — never use third-party "driver download" sites):
