This block is often due to the driver being outdated or not having the correct digital signature. Most of the time, this driver is part of Zemana AntiMalware’s software. Old or leftover files from antivirus programs you have uninstalled can also cause this problem. Now that you know the causes, let’s discuss the solutions.
1. Reinstall Zemana AntiMalware Program
The Amsdk.sys driver may be outdated or corrupted, which can cause Windows to block it. Drivers with missing or damaged files often lead to these kinds of problems. To fix this, you can update or reinstall the program to make sure it works correctly.
2. Disable Memory Integrity
Windows blocks certain drivers if they don’t meet its compatibility requirements. One main feature doing this is called Memory Integrity (Core Isolation) in Windows Security. Turning off Memory Integrity lets Amsdk.sys run.
3. Temporarily Disable Driver Signature Enforcement
Driver Signature Enforcement is a Windows security feature that blocks drivers that aren’t verified. Since Amsdk.sys might be unsigned, you can try turning this off temporarily to test if this is what’s blocking the driver.
4. Update Windows Including All Optional Updates
Newer Windows versions have stricter rules for drivers to keep your system safe. That means old or unsigned drivers like Amsdk.sys can get blocked. Microsoft often releases cumulative updates and optional updates to address driver issues. These updates could include:
A new, digitally signed version of Amsdk.sys.System improvements that help drivers work better with features like Memory Integrity and Core Isolation.
Many users have found that installing all available updates, including optional ones, can completely fix the problem. If you follow the steps above, the Amsdk.sys driver should load without any problems. However, if the driver still doesn’t load and you don’t need it, you can permanently disable it using the following commands in an administrator Command Prompt: This should clear the error message from your system.
