Although it is directly related to the usage of Kaspersky Lab Intruder Filter, a component of the antivirus program that protects against malicious sites, phishing, and the like, it ironically results in sudden fatal errors that harm your computer. The best way to address this is to remove the external security program. If that is not feasible, there are several additional solutions to this issue. So let’s take a look!
What Causes the Klif.sys Blue Screen Error
The best way to know which fix is the most effective for you is by determining the root cause of the problem. Here are several reasons why this BSOD error can appear on your device:
Corrupted drivers: The most common reason of this blue screen error is an issue within the Klif.sys driver. If it is damaged or corrupted, it can lead to various errors on your computer such as the stated one. Incompatible Windows update: Sometimes, installing a Windows update on your PC may cause the Klif.sys Blue Screen error. This is primarily because the Windows update is incompatible with the Klif.sys driver file.Other programs interference: Certain security programs also interfere with your system’s drivers, resulting in the blue screen error. By identifying such software and removing them, you can overcome this issue.
Now that we know the potential causes of this problem, lets start fixing this problem! Follow the steps down below to fix the issue.
Solution 1. Remove the Klif.sys from your PC

Solution 2. Switch From Beta to Stable Kaspersky Version
The beta version of most programs, since they’re in their experimental stage, contains various bugs and glitches. So, if you’re running a beta version of any of the Kaspersky programs, it could possibly be the reason for the blue screen error.
