What are SymEFASI64.sys Error Messages?


SymEFASI64.sys Blue Screen of Death (BSOD) Errors

There are a number of reasons why you could be encountering issues with SymEFASI64.sys. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors. These types of SymEFASI64.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. Norton Security Premium update) issues. Some of these errors include:

A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: SymEFASI64.sys.

:( Your PC ran into a problem that it couldn't handle, and now needs to restart. You can search for the error online: [BSOD] (SymEFASI64.sys).

<strong>STOP 0x0000000A: IRQL NOT LESS EQUAL (SymEFASI64.sys)</strong><br /><strong>STOP 0×0000007A: KERNEL DATA INPAGE (SymEFASI64.sys)</strong><br /><strong>STOP 0x0000003B: SYSTEM SERVICE EXCEPTION (SymEFASI64.sys)</strong><br /><strong>STOP 0x0000007E: SYSTEM THREAD EXCEPTION NOT HANDLED (SymEFASI64.sys)</strong><br /><strong>STOP 0x0000001E: KMODE EXCEPTION NOT HANDLED (SymEFASI64.sys)</strong><br /><strong>STOP 0x00000050: PAGE FAULT IN A NONPAGED AREA (SymEFASI64.sys)</strong>

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter SymEFASI64.sys BSOD errors after you've installed new hardware, software (Norton Security Premium), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to SymEFASI64.sys Blue Screen of Death errors. Therefore, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.


GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a SymEFASI64.sys Blue Screen of Death error after recent changes.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your SymEFASI64.sys issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the SymEFASI64.sys error, please proceed to the Step 2 below.

Step 2: If recently installed Norton Security Premium (or related software), uninstall then try reinstalling Norton Security Premium software.

Download SymEFASI64.sys Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying SymEFASI64.sys to your appropriate Windows system directory. Symantec Corporation typically does not release Norton Security Premium SYS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing SymEFASI64.sys and all other SYS files for Norton Security Premium. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
