Re: My computer caught a virus
Yes this is an unfortunate virus that has attacked your system at this time. you can clear all partitions and reinstall the entire operating system. this will bring back the OS but, you will lose all info that was stored in the partitioned drives. You can do this by inserting the xp or vista disk then, restart the system and before the dell bios flash gos away, hit f4 then, choose boot disk. this will start the reinstallation of the OS again.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

You should kindly explain how it started, what happened and symptoms you see. Try this: 1. When you try booting and you can see your operating system (OS) e.g 'Windows Vista' appearing on the screen and not giving you a successful booting, then repair repair Windows or formating using your Operating System software. OR 2. When you try booting and you can't see anything on your screen or not even a sign of booting, try and confirm if your motherboard is still good. And if bad a pin board can be fix and pinless board unfixablr.
Is your virus scanner updated? Some virus scanners will do a 'boot scan', ie scan at bootup. If yours will what you want to do is set it up to do a boot scan and run it. If it doesn't and you can still get online go download a free copy of Avast anti-virus and install it. Then set it up to do a boot scan and reboot the machine and let it scan. It will take a long time to scan the whole drive but you will want it to scan everything. Here is where you get avast http://www.avast.com/free-antivirus-download Once installed download the new updates.
Don't use the computer or do anything else until you have scanned it. Use whatever login windows will open for now. If you're lucky and caught it in time this may get rid of the viruses enough to get you back running. Then you will want to scan again.
If you can't get that far it gets a lot more complicated so try this first. If you can't get online you can get a friend to download avast to a thumb drive and install it from there. Make sure they use "save" and not "open" when they download it.
try to turn off the laptop and then remove cables & battery on it. Then press and hold the power button for 8 secs
Then, reinsert the cables and battery on it. And then turn it on, check if you still have the same problem. If symptom persist, consult your PC technician on it...
I would suggest you try to isolate the problem with a different computer. If it works on the other, then your workstation could be the culprit now. Try to do a virus scan if you have done so. This will help you track and remove trojans which normally causes this behavior.
If it also does not work with the other computers, try to do a network troubleshooting. Temporarily assign OpenDNS as your DNS servers:
If you need further assistance, let me know.
If the popup you're getting is from something like "MS Antispyware 2009" or similar, that's the same trouble I've seen on several other computers. Download a removal tool called ComboFix. You can find information on how to use it and links to download it here. This is a handy tool even if the virus you have is different as it will fix a number of virus and trojan problems. ComboFix can be run in safe mode if your computer can't start all the way into Windows. Turn your computer on, and when you see the Gateway logo screen press the F8 key. This will give you a startup menu screen from which you can pick starting in safe mode. This prevents Windows from loading everything except the minimum stuff it needs to start. Run ComboFix and let it repair the troubles it finds.
Tapping F8 key during bootup, to go in Safe Mode. Login as administrator.
After getting upto desktop, run the Checkdisk command and run a complete system scan with your Antivirus.
Let me know the status after this, I will further investigate and fix the problem.
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.
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:
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.
