What are isesrv.exe Error Messages?

isesrv.exe Runtime Errors

Runtime errors are Comodo Antivirus errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when isesrv.exe is attempted to be loaded either when Comodo Antivirus is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Comodo Antivirus.

In most cases, isesrv.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these isesrv.exe error messages mean that Comodo Antivirus was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Comodo Antivirus will be unable to start without resolving these errors.

Some of the most common isesrv.exe errors include:

isesrv.exe - Bad Image.
isesrv.exe Application Error.
isesrv.exe could not be found.
isesrv.exe could not be installed.
isesrv.exe could not be launched. Class not registered.
isesrv.exe could not be started.
isesrv.exe failed to initialize properly.
isesrv.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
isesrv.exe is not a valid Win32 application.
isesrv.exe is not running.
Cannot find isesrv.exe.
Error starting program: isesrv.exe.
Faulting Application Path: isesrv.exe.
The file isesrv.exe is missing or corrupt.
Windows failed to start - isesrv.exe.

System Error

The program can’t start because isesrv.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the isesrv.exe error is key to properly resolving these errors. Although most of these EXE errors affecting isesrv.exe will happen during startup, occasionally you will encounter a runtime error while using Internet Security Essentials. This can occur due to poor programming on behalf of COMODO, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of isesrv.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix isesrv.exe Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your isesrv.exe 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):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the isesrv.exe error, please proceed to the Step 2 below.

Step 2: If recently installed Comodo Antivirus (or related software), uninstall then try reinstalling Comodo Antivirus software.

You can uninstall Comodo Antivirus software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many isesrv.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the isesrv.exe error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your isesrv.exe File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate isesrv.exe file version. We maintain a comprehensive database of 100% malware-free isesrv.exe files for every applicable version of Comodo Antivirus. Please follow the steps below to download and properly replace you file:

Windows 10: C:\Program Files (x86)\Comodo\Internet Security Essentials\

Download isesrv.exe Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying isesrv.exe to your appropriate Windows system directory. Comodo Group typically does not release Comodo Antivirus EXE files for download because they are bundled together inside of a software installer.

An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
