I have three or more entries of svchost.exe in TasK Manager.
When I end the svchost process with the highest CPU-time
after som time i get the message that a shutdown is coming.
For that I am prepared in cmd to abort that shutdown.
Is this a virus.

I have a screenshot of task manager but I do not know how to send it to you.
Zone Alarm detected 55 attempts to go outbound.

Before that I had 1175 viruses all of them with names of
movies.
I removed them with a trial of Avira Pro.
I am using Virtual PC on a Mac G4 (QuickSilver) 2 processors
and 1.5 Gb core.

Have a nice day!!

Hello

My svchost.exe i guess it is infected
because each time i upload a file to my hosting, it looks fine, but after a while , i see a java script line added to my index page and this is malaware . in google my sites started showing that it this site might harm your pc.
i made format to my pc, and again i was attacked by the same problem,

I tried 4 different hosting companies, they said that someone has access to my passwords to do that, i changed password and still same problem.

i was reading http://www.liutilities.com/products/wintaskspro/processlibrary/svchost/

so how to deal with that?
thanks

Uh, Yeah, I kind of sent svchost to the recycle and screwed up my computer.

I really want my files back!!
Everythings due at school now so acessing files is kind of crucial!
PLEASE HELP LEO!!!!!

Hi Leo, I have deleted lsass.exe & smss.exe after my laptop infected with Funny IST scandal from the registry. I was not aware that these are windows files and essential for system to run. Now I am not able to boot my laptop, is there any solution for this?

Thanks in advance.

I had a virus in my computer. I instalalled a new virus scan nod32 which detected the virus and deleted a lot of them, togather with this i guess it deleted SVCHOST.EXE. NOw when I startup my compute. I get a message stating svchost.exe not detected.
I can't open my taskmanager also, which probably could be because of this.
I would like to know how can I Install an svchost.exe from and how can I get My task manager functiong

Please, do not even try to delete your svchost.exe-file. Doing that might destroy your system (not physically). It's the main process, which opens other processes when you start your system. The scvchost.exe-file is infected if it causes viruses. It should be replaced with a clean one, which could be done by reinstalling your operating system. There might also be a program that could repair the file. Blocking the svchost.exe isn't good either and if you attempt to stop it from the task manager it will send a pop-up with a timer. Then the countdown begins and the system will close in 60 seconds.

Try using regmechanic to make your computer faster, if that doesn't work, try looking for other processes that are disrupting your computer. I currently have 6 svchost.exe running, or more, and my computer is fine. I also recommend computer cleaners, like "CCleaner or Webroot Window Washer."

You can delete a virus by starting up in safemode. Then perform a search for the executable file. Find it and trash it immediately. You can only delete a virus in safemode, otherwise, if i you are using your OS in regular, the system will know its being used and wont delete it.

Isass.exe is probably a virus. Get a good virus scanner, make sure its database is up to date, and scan to repair.

But what is winlogon.exe, spoolsv.exe, or services32.exe...I ave noticed when i do scans with Adaware and HijackThis that alot of services32, system32, and win32 things come up? What is wrong with my computer?? I keep getting pop-ups.

I really don't know how to make it any clearer that the article at the top of the page: svchost.exe (in the system32 directory) is part of windows. svchost is required. If you delete svchost Windows will not work.

hey why do you say I need to leave svchost? I once had something from the internet which slowed down my comp(very badly) called istsvc. I managed to remove it with task manager. now I have this svchost, I have 7 of them and they slow down my comp too(not that much as istsvc). From what I know they are bad and need to be removed. I don't care if those things are not viruses or malware or they will mess up my computer, I just want to remove them. Please tell me how. I'm pretty sure that when I reinstalled windows I never had these things

Get to know your computer better! :)

As stated earlier, isass.exe can posibly be a virus, so run a full virus before you do this. Also run Ad-Aware (make sure you update these programs). I don't recommend "Microsoft Anti-spyware program (as Leo does above {not the real Leo}) as it is still in beta and loads more processes than it stops. By the way, by all means Keep "Xoft Spy Remover" (one of the best, "Spyware Blaster" is another very good one)!

ONCE YOU'VE DETERMINED NO VIRUS OR SPYWARE IS ON YOUR SYSTEM, PROCEED AS FOLLOWS!

Open = "Control Panel" =next= Open = "Adminstrative Settings"!
Now click on "Services"! Here you find all the services that are visable in your process manager.

THESE ARE THE PROGRAMS NAMED ABOVE YOU NEED TO LEAVE ALONE!
=lsass.exe (essential)=
=spools.exe (if you use a printer)=
=svchost.exe (maybe two of these with no problems=
=taskmgi.exe (is the window u r looking at: Task Manager)=
=csrss.exe (essential)=

IF YOU DID THE VIRUS SCAN!
=isas.exe (will be gone)=
=msmgs.exe "Messenger"(of no use to normal user and is often used to spam you with Official looking Windows Popups. This is a very simple network messenger not same as an online Messenger Program.
In the "Adminstrative Settings>>Services" you can right click/menu and choose properties. Click on the dropdown box next to it, Choose "Disabled"! If the process is running you can stop it here as well.

If you want to experiment with other processes then first look at the icons in the "Services" page. You will see one on =mouse over= called "Export List". Here you can save a list of the setup you have before you start tinkering. Preferribly get a screenshot of the "Services" page. This could save you if you make a mistake. But the saved screenshot will be much easier to decipher later. ;)

Best bet, before you make any permanent changes is to just stop a process for awhile and then use your computer. See if everything runs all right. If it continues to run fine doing everything you normally do, then you know you can "Disable" it. But write the ones down you disable on paper just in case.

Oh yes do have a "Firewall" installed and running. I recommend "Sysgate Personal Firewall"! It was recently bought by "Symantec" (Norton), but is still free and still better than their pay for one. ;)

Hello:

I have found the lsass.exe in my strtup menu today and can not uncheck it or get rid of it. I have scanned with my updated Antivir antivirus and virus detected. the file started today and it is in C:\windows\lsass.exe and not in system files. Also it is in HKCU\software\microsoft\windows\xurrentversion\run. in regedit says localauthority service in the HKCU. I have checked its properties and it says microsoft file and on the registry. I have checked it and all indications seems its a real window file but I do not know what to do? I appreciat any help. I think I may havegot it whan I downladed two new antispyware such as xsoft and pc spyware and adware remover. I have uninstalled these programs but it is still there.

If you typed it properly, yes. isass.exe is a virus. You should run a virus scan.

Why do you say thel need to be deleted? Very likely that your system WILL NOT RUN WITHOUT THEM.

2005-07-24T19:21:45Z

Leo,

Do you know what the fix for this is: I have XP-P. My Internet Explorer home page and desktop have been hijacked. Uniquely, the same invader opens my CD drawer every few minutes and throws up a sign saying I urgently need their security system because I have "evidence" in my computer. If I put a CD in my drawer, the pc no longer recognizes it, the screen that should show that drive as opening on command is blank. If I put my CD into the second drawer, which does not open by itself mysteriously, the pc says I do not have a disc in it. This has made it impossible to back up my files for a re-format.

Nortons 2005 SystemWorks and Nortons firewall has done no good, obviously. AdAware SE has found some objects in my registry but evidently cannot get rid of either them (although it claims to have at the time of scan) or whatever this intruder is.

Since I cannot find a name for it, I cannot proceed in any way other than to get an expensive re-formatting.

Hellp!!

Thank you.

I did a repair, and that didn't work completely either. So, I think you're right. I was trying to avoid that at all costs in case any of the data was infected, as this is a business computer.

I do have another solution which I'll share (thanks to my techie bro's suggestion), in case I'm not the only one with this problem:

1. Take out the hard drive and install it on a known-clean machine with updated virus scanware as a slave drive.
2. Do not access the drive when you boot the other machine
3. Do a virus and spyware scan (or three or four) on the slave drive
4. Reinstall the drive

Ya know... sometimes a system is so infected or messed up that the right thing to do is simply reinstall. From what you've described, that's exactly what I'd start with: a reinstall of the OS on top of your existing installation.

Thanks for all the great help here and the articles above. I know lsass.exe is infected (and there may be multiple viruses)

I'm running into a problem aborting the shutdown -a command on my Win 2000 SP1 infected machine.

The virus has disabled the shutdown command. I can't view the system32 or winnt folders (shows no files, even in explorer view). Can I run the shutdown -a command from the run dialog from a CD?

"D:\shutdown.exe -a" doesn't work.

I've run every virus software and spyware detector I can find, and nothing has cleaned the machine completely. I've hand edited much of the registry for obvious problem files I have (internat.exe, defragfatx.exe, macaddr.exe, winmedplay.exe, and a few others).

I am unable to install a software firewall, and I can't run Windows Update. Most name-brand detectors seem to be diabled or uninstallable or un-updateable (ZoneAlarm, McAfee, Norton won't work).

Any help is a big help :)

Ogbola: You need to read the two articles listed with this article. I can't tell from your description exactly what's failing when you try shutdown, but you may also need to grab a copy of "psshutdown" from http://sysinternals.com.

You're probably being infected or attacked as soon as you connect to the internet. You need to put a firewall of some sort in place before you connect. That's one of the steps outlined here: http://ask-leo.com/archives/000105.html

Hello There

When I boot up my computer which is running windows XP home edition, Just before it gets to the log on screen I get error message "Not enough Virtual Memory or paging file quota available to complete this operation". Then it reboots and does the same again. On the heading of the error message box it says Erroe - lsass.exe. I can not change VM because I can not get into windows (even in safe mode). I have important documents on there. What do I do???

Win2K SP4 (note, *4*) I believe has the patch as part of the SP. If you're back at SP1, then that's fairly old and wouldn't have the patch. LSASS can manifest as a result of several viruses. This article has more: http://ask-leo.com/archives/000114.html - bottom line is to get behind a firewall, and scan for viruses often.

When I'm running winmx and shut down my firewall (zonealarm 4.5) I get the windows screen indicating that lsass.exe has terminated and the system will shut down (w2k sp1 with all updates installed). My system scans as sasser-free and this error doesn't occur under any other circumstances, so I believe it's just due to the environment not the sasser virus. Can you confirm if other situations can cause the lsass to terminate (just plain old windows instability?)
Also, a second question - the sasser update doesn't install on w2k sp1, and they tech documents are careful to fail to mention it - is w2k sp1 not vulnerable to sasser, or is it wide open to sasser and the windows update wasn't built to protect sp1?

Don't know anything specific about that error. I'd probably have you run the system file checker, to start, and then a good spyware scanner.
