I have found that most malware is renamed, this is done for many reasons, the most effective bieng defeating firewalls and permission lists, letting the nasty normally run without the user ever knowing and typically these machines are compromised zombie machines. You certainly need to know where things are running from and most importantly why they are running.

Well, im still trying!! I got a big brake when i downloaded SpyBot!! I scaned my hd which only took about 2hrs and its found 52 files of which it couldnt delete 2 of them. U virus doing its bad deeds. Now, i cannot find anything on the net that can help me rid myself of this pest!! The only thing is on symatec but it means i have to buy it, please tell me there is another way!

Im a student, or soon to be, and im real short of cash!! Thank you so much for the help you have given me so far, even if it hasnt worked yet, im sure it will soon. Im still battleing away although i have a feeling i am aproaching the light. I found hijakthis before i posted on here but it would not run.

I have tried it again and now it runs for about 4sec before dissapearing into thin air, enogh time for me to creat a log. I will keep you up to date with how im going. This might be the brake i was looking for. While I might not suspect Sasser, I think your instincts on a virus infection feel right on.

Hi Leo I recently found a company laptop which kept attempting a dial up connection. I managed to get rid of it, but couldnt find anything on the net about it. Have you encountered it before and how can I protect against it? If you made a recovery disk when you installed your OS or if a recovery disk came with the system , you should be able to boot from that and rename the file. My monitoring system merely tells me on boot up that LSASS has changed since the last time I booted and wants to access the internet.

Really want to know how to stop it from changing and how to get rid of this continually asking to access internet. Absolutely nothing I do gets rid of it.

You can try any virus scanner available symantec, AVG, housecall, the microsoft tools. This thing sits somewhere else. My Win2k Prof. Hence I applied SP It boot well and comes almost near to the login screen and suddenly reboots, I tried to boot it in safe mode and in debug mode.. EXE errors, and protect yourself from further attacks, all as outlined in the accompanying article.

Leo, you have brought my sanity back, I bought a new laptop over the weekend, and that day got infected, this thing is rife! I followed your steps and now I seem clear. Thank you. My computer definately has this bug you speak of… I was soooooo relieved to see that it wasnt just me being a complete idiot, and was so happy that this site shows me what i can do. I am downloading the qi. My computer also has a few more problems. Not just lsass. I also get an error with this file, something like ftupd.

When i was completely clueless of what the problem was, i did the system recovery, i have no disk and now i cannon install my symantec firewall. I am sure this is a bad thing. What would you recommend that i do?

Is my norton anti-virus running properly? It seems to be but when i scan it finds nothing. Although it has said that it caught this threat; w Please help my situation. My guess is you are infected with something. My first place to look would be the hosts file I mention in the article. I attempted to check the hosts file, i found it, but i cannon open it. A messege says it cant open it, because it doesnt know what created it, so it says it can go online and check, and i get a page cannot be found, it tries to go to HTTP Bad Request- Microsoft Internet Explorer… I was very convinced it was this sasser thing that ive got, but ive probably got a whole collection … Ill start with trying the download for the sasser worm.

If problems continue ill move on from there… Well… thanks again- Beau. Instead of double clicking on the hosts file, run notepad, and then use File, Open to open the file directly.

EXE has changed since the last time it accessed the Internet. EXE to connect to the Internet whenever it asks? I am running Win2K. You may be infected with somthing — perhaps not sasser, but similar. What does this mean? Has the hole already been patched by my automatic updates? Then try and figure out how to turn on the firewall in my XP. I have a Dell Demension series. I have had the worst time with viruses lately. I have removed the sasser worm 3X and had a Sdbot worm and have the bobax worm.

I used trend micro Housecall to delete these files. My norton anti virus protection is somehow disabled and I cannot acess it for very long and it closes shortly after opening it. It will only stay open for a few seconds. I have removed and reinstalled this program twice and have two firewalls in place now. I am using the housecall trail protection for now but i want my Norton back.

Any suggestions. I dont know what is wrong with my computer. I cannot do basically anything on it anymore, so i am using a different one for now. Every time i log on, it waits a few seconds, then does the 60 second shut down thing. I downloaded the fxsasser. I went into the hosts file mentioned above, and there was only the one normal entry.

I would apprecciate any help. You may need to disconnect from the network, and possibly boot into safe mode or from a floppy of CD in order to run a virus check on your system. I have the lsass. THe best thing to do it to keep your virus signatures up to date, run virus scans periodically, and even scan with a second AV program from time to time. And of course follow the other steps in the article. I was wondering if totally wiping your harddrive and reinstalling xp pro will get rid of the sasser virus?

If it does will previous files i saved on a cd when i had the virus still be potential infectors? It depends on the files, but the short answer is probably yes.

The safest thing to do is to run a virus scan on those files before you copy them back. I try to find out wich one my friend has. My recommendation is to use a virus scanner and it will report which one.

Hey leo if you are completely updated with nortan antivirus and scan your harddrive should it detect the sasser virus? I am completely updated but i originally installed nortan Also i am expiriencing another problem. At some point a system file called svchost. If I end the process It will display the shutdown in 60seconds window. If i run shutdown -a it will stop but the taskmanager items retain their user identity instead of reverting to unknown and i regain my cpu power Is this the sasser virus?

Hi, I am not sure what I have and how to get rid of it. I get this before my PC fully boots so I am not able to go to my start menu or anything. Best I can do is hit F1 and go into setup. Is there anything under setup I can do to stop this from happening so my PC will fully boot? Brice: yes and no. The problem is that new variants are coming out every day, and the AV software manufacturer;s are constantly playing catch-up. Definitely keep your virus signatures up to date — I check for new virus definitions daily.

Perhaps even reinstalling it will be neccessary. Be sure that a firewall is in place before you connect to the network to avoid getting immediately reinfected.

I got the sasser virus, but I had no idea what it was. I cut the lass. I restarted the computer, but now it go at all. All I get is a black screen and the cursor works and that it. What can I do to solve this problem? Thank for the heads up, but I have the viruses in my Pc right now. Hi Shane: did you read the full article? I ran the removal tool and no sasser worm was found.

Also during Windows loading up and Login Screen, is my computer vulnerable? For example, can people hack to my computer or can virus and worms attack my computer during the Login Screen before I log in? Standard advice: make sure you have an up-to-date virus program, with up-to-date virus definitions, and scan. And to answer your question: YES the vulnerability that sasser and related viruses take advantage of does NOT require you to be logged in.

Either of those will block this vulnerability. I ran symatec and microsoft removal tool and found no sasser worm. I went through the registry and found no sign of the sasser worm. It may not be Sasser that you have — there are several viruses now that have similar symptoms.

Thanks for the great info you have here. I checked the hosts file in system32 and everythings fine there, but i cannot sign into hotmail,and ive been having problems with an exponentially slow dialup, after 40 seconds of connecting to the internet, it completely stops. I cannot find what, if anything is taking my bandwidth. Because i cant sign into hotmail, i cant continue to dl Norton antivirus. What antivirus software do you suggest i dl, and does this just sound like a sasser variant, or more than 1 virus?

I have yahoo dsl and have located the lsass. I reset my modem and it connects for a short time then disconnects. I have updated my virus scan and ran it.

I was wondering if this is virus related? Trin: Your best bet is to get an Anti-Virus product and current definitions on a CD-Rom — then disconnect your machine from the internet and run the scan.

It could be any of a number of things. Yes, a software firewall will help and give a certain peace of mind, but it may not be bombproof.

I have Norton Personal Firewall EXE access the internet. EXE was. I am glad I did! But at least the firewall brought it to my attention. I feel a bit safer now. My PC is shuting down every 15min it is showing error of your windows going to shutdown within 50seconds ther is some error in lsass. It is a required system file. You need to identify which virus you have sasser, or some other , and then remove that. The best approach is to use an anti-virus software package. My firewall asks if I want to continue.

It appears in my task manager and starts to sap all cpu power. I can end the task and get all my speed back but the next time i reboot it appears again.

Does anyone know what virus this is and how to stop it? Will it get worse? You should run a spyware scan and that should clean it up. It is very probable that sasser has overwrited the file lsass. It typically means booting from floppy or CD to be able to correct the error. Get and run an up-to-date virus scanner. I am attempting to download the patch and use the removal tool, however shutdown -a does not stop the shutdown process on my system.

I am running Windows Hello I believe I have sasser or some variant. I have formatted my C drive and deleted all partitions several times but as soon as I reinstall the Operating system windows or Xp I get a reboot error within 60secs and error from lsass. It is incredibile. I though that a format C: would have got rid of this virus. Do you have any help for me? I am despeate. Please help. Are you on a LAN with other machines?

Physically unplug from the network and see if that allows you to get further.
