Kaspersky — Kaspersky filter driver

When blamed in a crash: Very likely the true cause

What to do

Kaspersky's kernel filter.

  1. Update Kaspersky to the newest version.
  2. If crashes persist, remove it with Kaspersky's official removal tool (kavremover), reboot, and reinstall fresh — or stay on Defender.
