The worst case? It’ll destabilize the system and you won’t be able to boot at all. A quite prominent error for Malwarebytes users is the “mbamswissarmy.sys” boot error when the antivirus driver gets corrupted. We come up with a few solutions thanks to the diligent community Malwarebytes have. Check them out below.

How to fix mbamswissarmy.sys corruption issues

Solution 1 – Boot into Safe Mode and uninstall Malwarebytes with MST

This is the best and the safest method to deal with this issue. Namely, it seems that this massive problem occurred due to the corruption of mbamswissarmy.sys driver. This driver starts up with the system and deals with on-boot cleaning of deleted or quarantined malicious files. Thus, it needs to start with the system. And, furthermore, as its an important startup component, its corruption will lead to boot failure. If you’re unable to boot in a standard manner, the best way to deal with this issue is by booting into the Safe Mode and uninstalling the Malwarebytes antivirus. The best way to do it is by using the MST (Malwarebytes Support Tool). With it, you can remove all associated files and registry entries. After that, it should be easy to reinstall Malwarebytes. Follow these steps to download MST and then boot into a Safe Mode:

Solution 2 – Delete or rename the “mbamswissarmy.sys” file

If the previous step failed you and there’s no chance to boot into Windows, even with the Safe mode, this next step is what you should try. Firstly, try booting into the Safe Mode again and navigate to C:windowssystem32drivers and rename the mbamswissarmy.sys to mbamswissarmy.sys.old. If you’re unable to do so, continue below. The main goal is to get to the elevated command prompt which should enable you to delete the mbamswissarmy.sys driver from the system. Even though this isn’t exactly a risk-free solution, it should resolve the error at hand. SPONSORED There’s a certain risk of critically damaging the system. However, in more than a few reported cases, affected users had no further issues. On the other hand, if you’re unable to delete or rename the driver, you can prevent it from executing by removing its registry entry. This alternative workaround should get you going and allow to boot without any problems. For both options, you’ll need an external installation media and an alternative PC to create it on. Follow these instructions to deal with the “mbamswissarmy.sys” driver and boot into Windows 10:

Solution 3 – Backup your data and reinstall Windows 10

Finally, if none of the two previous steps helped you address the problem, the last resort would be the system reinstallation. Of course, make sure to use a third-party tool or command line to extract all important data before wiping the system drive. After you’ve done that, you should have a simple task to download the Media Creation Tool and create the installation media (DVD or USB Flash drive).
