lsass Exe Errors and Ways to Prevent Them

Jul 6, 2008
Isass.exe errors can be serious. lsass.exe is actually the Local Security Authorization Server, and it is responsible for the verification of the user logon validity for any attempt to log on to your computer. This process deals with login policies and local security on your system. This program is needed for applications which are essential to your computer, and disabling it may cause system damage or even failure. There is a worm that has a name which is identical, except the first letter is a lower case i instead of an l, and this can confuse your system into thinking the virus is a valid program. It is critical you can eliminate Isass.exe errors for PC security.

Isass.exe Errors And What You Can Do To stop Them

When you get an error concerning the lsass.exe program, the first step you should take is to run an anti virus program, to determine if your system has been infected by the worm of the same name. This is a common cause of lsass.exe errors on many systems, and the anti virus program or worm removal tool will allow you to remove the worm. Once the worm is removed, you still should not rest easy. With Windows, every program you remove can still leave traces in your system registry. These traces need to be cleaned up, and there is software which can help.

If your anti virus program does not show a worm or other malicious software program, you may have problems with corrupted files or fragments, missing data, or a corrupt or packed registry. If the files needed for lsass.exe to work are missing or corrupted, you may have to remove the program and re-install it, and this can be tricky, because this program is an integral part of the operating system. Most users would be better off letting a technician do this, but first you should try all the other methods listed to fix the error problem. Why pay them if you can easily do it yourself and prevent Isass.exe errors?

No matter what is causing the lsass.exe error to occur, run an anti virus scan and then use a registry cleaner. These two steps are all you need to do to stop these pesky messages from appearing all the time. The anti virus program will remove the file if it is a worm, and not a legitimate operating system program, and cleaning the registry will solve the errors whether it is a worm or not. Your system registry also affects the speed and performance of your computer, and cleaning the registry will make your system much quicker and more efficient.

A registry cleaner program is the safest and fastest way to clean your registry. This software was developed to avoid the risks and time needed to manually edit the registry, because of all the critical entries that are contained in it. If you change or delete a program that Windows needs to run correctly, you may have worse problems than an error message, and a registry cleaner prevents this from happening. This software only takes minutes in most cases, and then you have a registry which is clean and operates much faster and more efficiently, stopping lsass.exe errors before they start.
