Question about Microsoft Windows XP Professional

1 Answer

I got the lsass.exe virus and now my computer won't even load up. It goes a black screen and that's all. Drivers and other files say they have been moved or deleted. I am running Vista and system recovery and restore to the previous good state will not work. The computer will only load up in safe mode. How do I fix this or fix my driver's that the virus caused? Please help. Thank you!

Pls advise if the following processes running in my Task Manager are viruses or genuine system processes - ccSvcHst.exe; lsass.exe; explorer.exe, winlogon.exe; svchost.exe; wuauclt.exe; jqs.exe;...


ccSvcHst.exe - works to display the GUI (Graphical User Interface) of Norton products, which usually include the Norton Security Suites.
lsass.exe - Disable and remove lsass.exe Immediately. This process is most likely a virus or trojan.

Other processes are required for essential applications to work properly.

You can visit this liutilities.com and search for the process your not familiar with.

How to fix lsass.exe error


hello

for a simple fix, try this -- if not go to the next step

From your post, I understand that you cannot manage to boot or logon into Windows.
lsass.exe is a favorite target of viruses, and it's likely that a virus has destroyed lsass.exe while trying to infect your machine.
If you can boot into Safe mode (F8 during the boot), restore your system to an earlier system restore point. Then scan your disk using several anti-virus programs.
If you can't boot into Safe mode, try to boot into the Last Known Good Configuration (using F8).

If that also doesn't work, you should --follow these steps

How do you perform a reinstallation of Windows XP, sometimes called a repair installation?
Configure your computer to start from the CD-ROM drive. For more information about how to do this, refer to your computer's documentation or contact your computer manufacturer. Then insert your Windows XP Setup CD, and restart your computer.
1.
When the Press any key to boot from CD message is displayed on your screen, press a key to start your computer from the Windows XP CD.
2.
Press ENTER when you see the message To setup Windows XP now, and then press ENTER displayed on the Welcome to Setup screen.
3.
Do not choose the option to press R to use the Recovery Console.
4.
In the Windows XP Licensing Agreement, press F8 to agree to the license agreement.
5.
Make sure that your current installation of Windows XP is selected in the box, and then press R to repair Windows XP.
6.
Follow the instructions on the screen to complete Setup.


If you still have the lsass.exe error and your Windows keep restarting or you can't even open Windows anymore, its because the error has a small problem in the lsass.exe file itself. This is not a hard issue to rectify . In fact, it isn't really that hard to fix.

To get this problem fixed, you need to repair the lsass.exe file by getting a PC repair program. This program will scan your computer to detect the error and to repair it. Also, it will allow you to recover files that are missing and it will repair or delete the files that are causing problems to your computer.
This PC Repair Program will work- The PC REPAIRING PROGRAM works by an automated process. First of all you will have to start the scanning process while using this program. Once the scan is done, you will get a list of troubleshooting files.
It will also show the lsass.exe error file. Once you've spotted this file, you simply select the category and you press the repair problem button and it will start to repair the lsass.exe file. Once the repairs are done, you simply restart your PC and it's fixed.
This program will not damage any of your software programs already installed. It even allows you to create a backup file from your hard drive.
This software tool will also help you to detect other problems like viruses, worms, cookies and even pop-ups. This way, your computer will be cleaner and faster then before.

So, to repair the lsass.exe error you will need to get the Registry Easy program so you can start a scan, detect the lsass.exe file it's problem and start repairing it.

Want to start up Windows again without any problems? Today? Right now? Visit: Regcure.


lsass.exe is probably located in the folder C:\Windows\System32. Known file sizes on Windows XP are 7k-33k bytes long .space.gif
It is a Windows core system file. The program is not visible. File lsass.exe is a trustworthy file from Microsoft. Program listens for or sends data on open ports to LAN or Internet. Therefore the technical security rating is 9% dangerous.

lsass.exe is harmless and if u kill it, it's likely to reboot or revert to welcome screen. two famous viruses are lsass.exe begining with an "I" or ending in triple "s"

lsass is a legitimate Windows object for user authentication but it is vulnerable to the sasser virus and can be HiJacked. Someone please clean up this place as at least half of the entries are worthless. it may be a trojan (form of virus) named SASSER

please rate me with 4 thimbs up

Windows xp won`t boot up. Get error messages services.exe and Lsass.exe and screen goes black...thank you....


Unfortunately, Lsass.exe is the security policy manager for Windows XP. You only options will be to try and press F8, and choose "Last Known Good Configuration." If that doesn't work, you will need a Windows XP CD. Enter that into the drive and boot to the CD. Go to Repair (not Recover Console). This will rebuild Windows XP, and keep your data intact.

Good luck, and I hope this helps somewhat!

On startup, i get the message: Isass.exe - Access Denied


Information on lsass.exe - http://www.neuber.com/taskmanager/process/lsass.exe.html

Are you running a firewall (such as zonealarm)? It might be your firewall may be blocking a legit attempt by lsass.exe to run. You may have to add this to your firewall's allowed list. Of course if you are not running a firewall or if your firewall is already set to allow lsass you may have even greater problems.

Funny UST scandal virus


Hai Rupaaa,
Your computer is infected with the brave killer virus. It would not allow you to open any utilities, even explorer, its an autoclose software.
Try this,
As soon as the computer boot up, press Alt+Ctrl+Del buttons
If it holds there, quickly find and select the killer.exe file and press End Task button.
If your computer is having an updated antivirus scanner, start the scan immediately.
If no antivirus installed, download one from another computer along with its updated virus definition. I recommend McAfee with the latest sdat5315 or later available in the site.
Try to install the antivirus and start a full scan.
You will have to try many times to remove the virus.
Hope this will solve your problem

Geforce 6800GT conflict with windows xp pro


Have you run a virus or spyware scan of your machine? Is your virus and spyware up to date? While running @ 640x480 does it exibit any other errors? lsass.exe is a system process of the Microsoft Windows security mechanisms. It specifically deals with local security and login policies. This program is important for the stable and secure running of your computer and should not be terminated. Note: lsass.exe is a process which is registered as a trojan. This Trojan allows attackers to access your computer from remote locations, stealing passwords, Internet banking and personal data. This process is a security risk and should be removed from your system. Note: lsass.exe is registered as a downloader. This process usually comes bundled with a virus or spyware and its main role is to do nothing other than download other viruses/spyware to your computer. This process is a security risk and should be removed from your system. DON'T REMOVE THE LSASS.EXE let a virus/ spyware program determine if its good or bad. http://www.filehippo.com you can download virus cleaner (avast is my favorite virus protection) windows defender, spybot S&D, AdAware, HighJack This to clean the machine. Then download and install the latest drivers from here: http://www.nvidia.com/content/drivers/drivers.asp Driver Installation Hints * "Download Accelerator" utilities should be disabled when downloading any drivers. * Do not run virus protection software in the background while installing the drivers. This prevents the driver from configuring itself properly. * Before installing new drivers make sure you uninstall all NVIDIA display drivers from the Windows Control Panel. Browse to the Start Menu > Windows Control Panel > Add/Remove Programs and search for "NVIDIA Windows Display Drivers" or "NVIDIA Display Drivers" and select remove. Get back to me if none of that works. Good Luck, Tim
