Have you done the restart like it said? (Restart required)

[Migration User]

Install NTP as well and Enable Risk Tracer in File system auto-protect
In NTP the IPS will block and log the entries of attacking PC.
Risk tracer will show you which computer is attacking 

It can be Via USB as well..So clean everything in  temp folders

[Fatih Teke]

NTP is meaning Network Therath Protection? it is install already. I close risk tracert because i was affaid it will be reason slow network. I will open it again.
But Mr Vikram I bloked USB Devices With Application and device policy already.
and there is one more thing. i want to know "how downadup can create service on this computer?" If it can create service why my SEP client block it Before create service? because Downadup create service after that SEP understand it is a virus service. why sep understand before? I looked logs and sep services works good. didn't stop.
I love SEP realy love it. very good program but i am asking to myself am i doing wrong? I want never infected computer in my WAN.
Is it posible? Am i want imposible thing?
Thank you for answer Mr Vikram.
Best Regards.

Hi, try to scan of safe mode first. Run also the Removal Tool: http://www.symantec.com/content/en/us/global/removal_tool/threat_writeups/D.exe

Can you post the risk log, and lets analyze the first infection.

Based from your post,  your pc is the source, you may not have removed the downadup completely.

[pete]

hi,
as from the capture the source is localsystem is the source.
check is Autoprotection is on on this system. Since the detection has been done, you need to reboot the system to completely clean the file ( threat partially cleaned).

As Paul mentioned scan the system in safe mode,  if the threat is memory resident then it would be detected in safe mode.


good luck!
Pete

[Fatih Teke]

I have got d.exe for remove downdup. I'll use it in safe mode. you mean this client never clean? i don't think so d.exe will help me. Because i try it another infected computer.
I will try in safe mode  and i i will write again. But this is not my answer. I want how it be posible?
there are 2 things in my head.
1- this clieant already have Downadup since april 1. and sep cannot clean it.
2- this client new infected?

Am I wrong?

[pete]

not exactly, if the process is use, then you need to scan it in safe mode. Becuase it locks certain dll's.
 
The infection is from localhost, hence it could have been infected when SEP service was not working.

check the other detection logs as well.

Cheers
Pete

I had this problem before, did you just use again a usb drive? You need to run the removal tool with the usb drive still inserted so that it can be cleaned also. Check the log it generates after you run the rmoval tool.

[Migration User]

Hi,

Let me know the No of users in your network and No of Branch office connected.

Downadup virus is too good.  Just plays from the other way.

Like If your account are getting locked out.  These Bad Credentials will sent by other infected systems on your login id.
 
Ex:  There are 5 systems in Network A,B,C,D,E
System C (infected system)

System C  will be trying to acces the Domain Server by sending Bad Credentials using other system accounts of  A, B,D,E.

Then accounts of A, B,D,E will be locked out.

But the user will be in impression that A, B,D,E are infected.

The best way is to schedule Custom scans on all the systems for Windows, System and System32 folders Daily and set the options to delete because this worm spreads by using shared folders on networked computers, to ensure that the worm does not reinfect the computer after it has been removed Sharing should be with Read Only access or by using password protection.

[Fatih Teke]

i have 2 weekly scan already. I read about Downadup. yes it is very good. But still not my answer.
How Downadup can infected my computer in 25.06.2009?? I told before Sep is have last definition,sp3 and latest pacthes.
but i can be infected..
Am i wrong or what is the problem?
Thank you for asnwer
Best regards.

The thing is that there nothing perfect in the world, their will never be a software that will catch 100% of the virus out there. Even if they upgrade the software, they also "upgrade" their virus to be tougher to catch. It will never end.

[Fatih Teke]

@frank019
I know what is perfect. But we are talking about Symantec. And did you know whan can the downadup do?? i lost very much client !!! Thats why i must to be very carefull and must to follow every action.
The Downadup start april 1 and now 3 jully.  I am asking Am i wrong or what is wrong???
I already Sep clients and windows with Wsus. please tell me what can i do more?

[Migration User]

"But we are talking about Symantec" it ain't perfect either. Try other anti-virus software if you think they are better. I might not know everything downadup can do but it the computer world. Something you have problem that won't be fix. Worst case you have to reformat.

[Migration User]

Enable the Risk tracer.

Downadup is the virus which keeps on apreading into the network untill and unless the entire network is patched up. Suppose if u have a network of 100pc and out of that 90 machines are win patched up but 10 is still to be patched so that downadup will try to affect the rest 90 machine from th 10 machine but though the 90 machine is patched up so it won't affect it.

My advice to u is to patch ur entire network either manually or using WSUS

Ajit

[Migration User]

Have you try that?

[Migration User]

Ok post the Risk Log post the first infection.. then lets analyze.

[Migration User]

We also had this issue when clients were using their infected USB..
The removal tool realy helped.
but sometimes since they tend to remove thier USB without cleaning and placing it to another PC tends to infect the next PC...
thanks...

[Fatih Teke]

first thank you for answers.
All usb disk closed by device control in "application and device control policy" thats why it cannot access with usb. 
@Paul Mapacpac how can i import risk log in here? copy paste or another?
Thank you.

[Migration User]

On the client pc, Open SEP, go to Logs, choose risk log, then export the risk log.

when did you disable usb access, is it before or after the infection?

[Migration User]

How about getting the logs from the server side?

[Fatih Teke]

@ paul
I know how i export risk log :) but how can i import in here? I can upload picture but can i upload doc files?
@ Mon_raralio

i taken mail from server like this;

Message from:

And everyday i taken full report from server. I can see infected computers in report.
Best Regards.

[Migration User]

Copy and paste the log file

[Migration User]

This computer might be infected some time back when this system was not patched and it downloaded a bot on this computer. Which was doing nothing but just waiting for commands from its master server..then once Downadup sent command to upgrade itself or download the new variant..it might have downloaded it and then it installed it most probably at the time of  bootup and once Auto-Protect was enabled it detected few files but since mopst of the files were installed in thememory or were runnig as rootkits so sep was not able to detec it..so they get detected only in safe mode..because in safe mode no 3rd party application work.

There is one universal truth that everyone has to agree "Once compromised..Can never be trusted"

This is all I can think of why you got infected.

[Migration User]

did you try to check your version of SP3? i mean is it really for XP? or did you try downloading it again and also the security patch as well? if not, then it might help somehow resolving your problem.... before installing the SP3 and sec patch, removed first the clients workstation from the network, because downadup will continously  gets in to your system. (do the installation and full system scan in safemode)

[Fatih Teke]

Vikram Thank you for answer. you should be rigth. i am going to copy and paste risk log in here tomorrow.
Please don't understand me wrong.  I never say SEP i not good. No doupt ! i am asking to myself Am i doing wrong thing? Because I must to control 500 clients and 30 server only myself. And If I cannot do that I must to find a new job :((
 Thats why i must to be sure My system is work fine like another security admins.
 I am doing 2 schuled scan in week for clients. and 2 scan for servers. and I was open risk detector.
Please don't understand me wrong. Because I  know my English is not perfect. I just want never infected computers.
I will paste risk log tomorrow in here.
Thank you again for answers.
Best Regards.

[Migration User]

Cannot see the path of the infection, you must really post the risk log.

[Migration User]

When did you patch the compute? The patch was released october 2008 and downadup was discovered nov 2008, fyi

[Fatih Teke]

i saw today client infected again :( i paste it down side. i didn't paste all

From the logs it seems the same file "hmdutoi.dll" is getting re-created or downloaded everyday.Then Auto-protect is taking its action.
I suspect there is a downloader on your computer which is downloading this file everyday or everytime it is getting deleted.
Most probably it is a rootkit and it is a new one that is not getting detected
c:\windows\System32\BAY596 looks like a suspicious folder
If you are not able to browse to this directory in user mode then download Icesword120_en and browse this location and find what other files are there in this location.Also check the services using this tool to check if there is any SYS file with any suspicious name.
Until and unless we find the main threat this will keep coming.
As a workaround you can block this DLL using application and device control for the time being till the main threat is found.

[Migration User]

Vikram is correct, it seems that a process is still recreating the file, please scan under safe mode and run the removal tool.

Please also run the Loadpoint Diagnostic Tool from Symantec, then post/attach it here so we can analyze.

[Migration User]

Hi mon, more detailed logs are on the client side.

[Fatih Teke]

I scan system32 now. and there is nothing infected. I download Icesword120 and there is no hmdutoi.dll  file.
I'll block this dll. but Downanup can create random dlls.
you said "Most probably it is a rootkit and it is a new one that is not getting detected " but sep definition time is 07.06.09 (m.d.y)
is the symantec will create new definition for this problem? I can send all log from this client.
Now i will block dll.
Best regards.

[Migration User]

Yes...Symantec will release definitions for the file ..but it should know which file it is and definitely it is not hmdutoi.dll
I would suggest you to call support as they will gather Loadpoint logs analyse it and will tell you to submit suspicious files. 

[Migration User]

Did you run the tool in safe mode? What are the results?

Hello Mr. Vikram.
I use this tool and export report. \Sym_LoadPointDiag how can i send it to you? or attach in here?
Best Regards

[Migration User]

In this log there should be an HTML log
that should be there in C:\Symtemp\Sym_Loadpoint...zip
You can attach it here.
 

[Fatih Teke]

there are many files in there. i add picture down side. please tell me which log you want it. there is  ESUGLPDU.html but it have got many information. i couldn't paste in here. If you say which information you want i can paste in here.
By the why realy thank you for help.

[Migration User]

I think he want the ESUGLPDU.html since he said the "HTML log"

[Migration User]

Yes you can attach ESUGLPDU.html ( ESUG Load Point Diagnostic Utility ) 
This file is zipped and is password protected the password is "symantec"

[Migration User]

Just attach the zip here, then we will just download it.

[Fatih Teke]

hi Paul.
I am sorry I cannot upload zip file in here. Because i don't know how i do that :( there is only picture i can upload. How can I upload it in here? :$

[Fatih Teke]

Hello again.
I am realy need your help. My boss want to result about this problem I said " this is new variant and symantec will deploy new definitons" but I must to be sure It cannot infect another computers.
How can i import zip file in here?
Best Regards.

[Migration User]

just update urs operating system.

[Migration User]

Hi kajal, fatih already patched the operating system we are now currently wailting for the Loadpoint Diagnostic Log from sir fatih.

fatih, upload the file, on this thread, click the edit on the top, below the menus.

[Migration User]

 Couldn't fnd anything suspicious from the log files...I compared it to the Loadpoint of my computer..and searched for the unknown ones..
However I am still looking into it..but if it is a Rootkit it wont show up in loadpoint thats what fears me.

Here is the location of HTML Log  file for Paul or if anybody else interested in analysing it.

http://www.2shared.com/file/6622810/59a01212/ESUGLPDU.html

[Migration User]

Hi fatih, i have checked the logs and it seems normal, another request, can you list the directories on the root drive (please include the hidden files and folders), i have encountered before a virus which is not visible on the task manager but the process is running using explorer.exe.

[Fatih Teke]

I can look working exe with sysinternal tools. It show every application if it working. better than task manager.
Vikram said  there is no suspicious file. but you saw the all logs. there is no problem but downadup infected.
I'll write c:\ folders (with hidden folders)
Best Regards.

[Migration User]

Just do a dir /ah > c:\log.txt

I was checking the latest alerts in our SEP environment. A lot of W32.Downadup came from temporary Internet files with jpg extensions.
Contrary to what the previous articles have said that it spreads using autorun.inf, it seems that they found a new method of spreading the threat.

So if you are still getting alerts on this, you can check what files are being detected. They will keep on coming back unless you block the source website.

[Migration User]

Can we inspect more on these folders?

Hi mon, what do you suggest? Fatih should post websites visited? (history)

[Migration User]

That's a tough one to fix, like if the website in question is in the Intranet and the web designer uses infected files. And you can't force other companies/web owners to scan their files before uploading it to the Internet or if they are protected against code injection. Just check if the infected file were properly treated by SEP for starters.

[Migration User]

Hi everyone!

I have the same problem with the SEP & w32.Downadup. Client have got Win XP SP3 and SEP client with last virus definition.
The virus was on a USB key and SEP does not block it. Downadup blocked several accounts in the domain. SEP has removed the virus after system reboot.
I had two such cases in the last month.

[Fatih Teke]

I saw logs now. the last attack 07.07.09 after that there is no new attack. is this machine now safe?

[Fatih Teke]

My server taken downadup still. it have last pages and last updates too. like another pc upside.
I add picture in here again. I look source its "local host" risk tracert is open. Why i cannot see the source? and what should i do for this computer?
I need your help.
Thanks.

[Fatih Teke]

please share me your ideas with me. If symantec need my reports for create new virus definition i can send all information.
Please Help.

[Migration User]

@Fatih Teke: W32.Downadup.B seems to be deleted by Symantec. And unlike your first post which are dll infections, these are temporary internet files with extensions used by picture files. Have you updated your OS with all the necessary security patches?

[Migration User]

Any updates on these folders? Are they all valid?

[Migration User]

I believe fatih already updated the system, it seems the infection came from a website.. check the ie/firefox history.

[Migration User]

try downloading & installing rapidrelease defs & scan the pc in safe mode once.

[Fatih Teke]

the last picture taken from server 2003 and need a few security updates. Now I am checking them. But Why wsus don't send update to this server I don't know. I hope this problem will resolve with this update. I  will write result after the update.
Have a nice day.

[reza akhlaghy]

Hi Faith,

Open services.msc then sort based on descripton column. If you find two services with same description then your computer is already infected with Downadup and it is download its complement from internet. One of those two services with same description is virus and the other is legitimate. For discovering it you need to open properities of each service and if you find garbage name in "service name" field then you find your service. You need to delete it with this command "SC DELETE <garbage service name> " and reboot and rescan. Symantec will take care of rest.

[Fatih Teke]

Hi everybody.
I think so i solve this problem. i didnt take attach from yesterday.
I check updates and one security updates need. (why wsus don't install it I don't know. I am not sure this happend for this security update.)
and scan in safe modde.
Now I am looking risk log. there is no attach more.
Thank you for answers
Everybody helped me for this problem.

[Migration User]

Hey !! Sounds great..Its always a happy moment when we you get this of this beast.
Anyways will suggest you to still monitor it for a day or two.

[Fatih Teke]

You rigth Vikram. I will watch it. Now i am looking why wsus don't send this update this client? Thank you again.
Have a nice day

[Migration User]

Hi Fatih Teke,

I have same problem, u got solution ???

If u got solution then plz also help me because i am also facing same problem in my organization.

I am waiting for ur response for how to fix this problem...

Thank you very much for gr8 help in advance....

Thanx & Regards,
Kailas

[Migration User]

Please read this document from Symantec about Downadup

http://www.symantec.com/security_response/writeup.jsp?docid=2008-112203-2408-99

Make sure your systems have the latest windows updates especially the Microsoft Security Update for Windows XP (KB958644)

You can also download the removal tool which is stated on the KB (Downadup Removal Tool)

Scan your computer on safe mode and make sure you have the latest virus definition updates.

[Peterpan]

some of our enduser say that Symantec is very uneffective when it comes in detecting a virus particularly in downadup issue, although SEP can detect and delete downadup but it cannot totally block, please expedite the recommended solution before we lost a clients.

Take note it must be automated

[Peterpan]

any automated solution for downadup virus because if our worstation is about 3000 PC's and most of this are infected of this kind of virus, do you mean I need to touch every worstation just to patch and scan in safe mode, it so very time comsuming and difficult to do so.

[Peterpan]

any other update on this thread?

[Migration User]

In SEP, assuming that all the definitions are updated, will treat the threat as soon as the OS and Symantec has the ability to modify or remove the file. This is usually when the file has completed downloading. If you'd check the user's logs, you'll find that the threat was treated one or two tries after initial detection. If this is wrong, post a screenshot of the risk logs. :-)

[Fatih Teke]

Hello Peterpan.
I did it like this.
First Check all security and critical updates. all must be install on machine.
Than update SEP.
close autorun.inf both of Active Directory Group Policy and SEP "Application and device manager"
and change your  antivirus and antispy rule. I change it first action and second action.
first action is delete second is move to quarantine.

[Peterpan]

I tried that solution on one pc's but after few days downadup will recur? what is the possible cause of this, do I need to patch all other pc? before downadup remove on my network?

[Fatih Teke]

Yes. You must update all pc in your company. Because i know downadup is very very fast and Clever. It try to crack administrator password if it easy. and try to copy itself in another networks.
you cannot delete downadup if pc need update. because SEP don't close windows's backdoors.
I know because I saw it.
my one pc taken attack from downadup everyday and every hour. Sep was update. but I saw computer need one critical security update. when i install it there is no more attack from downadup. (you can see pictures upside)
have you got a Wsus in your company? you must to install it for update. It is realy important. you can lost all computers. I know because we did :((
we install 5 servers (one of them domain controller another 2 server was addional server) and more than 100 pc.
(as you well know we install DC thats why we join all pc in new domain. Its take more time..)
I saw what downadup can do ! thats why please be fast and update all your pc in your company.
If your windows updates is ok and sep is update downadup cannot be infect.
Please write again if you have a problem or anything.

[Migration User]

Change your all AV actions to immediate delete. You'll see that infection numbers will decrease in time.

[Fatih Teke]

yes bekir you rigth. infection numbers decrease.

[Mithun Sanghavi]

“Best practice”for Win32/Conficker.B [MS] - w32.downadup.B[SYM]

Infection/propagation Method

-Flash drives/open shares/mapped drives [autorun.inf]
-Admin$ - Random brute force password attack on the networked systems
-Exploit MS08-67 – RPC BO vulnerability in netapi32.dll

How it works ?

Initial attack happens on one of the networked systems.

This initial attack and execution can be achieved by visiting any malware hosting website [cracks/music /free download/hacked etc.], plugging infected flash drive in the production network.

Mostly un-patched systems/Browsers are the initial victim of this attack.

Once executed it Installs a service under

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost\ netsvcs
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BadServiceName

This service is most of the time a .dll file [We need to submit this one if not already detected by SEP]

The service uses MS task scheduler to create multiple jobs
These jobs executes a file rundll32.exe random_name.random_ext <args> at random interval
These extensions are not always .dll it could be anything [i.e. .ifs,. jpg, .tmp, .c]
In task manager we’ll see multiple rundll32.exe running
That file in most cases detected by SEP not we need to submit that file.
That’s the file which again may attack other systems or download other threats.
Multiple instance of this file continuously runs in the memory and attack other systems.
The threat tries to plant autorun.inf & random_name.exe file in the mapped drives and open shares to execute itself across the network.
It also disables Automatic Updates, Background Intelligent Transfer Service (BITS), Windows Defender, and Error Reporting Services are disabled.

What’s the bad part ?

User account lockout policy. As known the threat tries to gain access different systems on the network by brute force password attack.
Because of this activity multiple users accounts get locked up. Apart from that the threat also may download multiple threats like w32.saility [a file infector] which would make the story even worst.


What is the PLAN OF ACTION if I get a case on w32.downadup.B

- Confirm in SEPM that all systems are with SEP up and running and up to date [with all the latest security updates from MS]

This step is very critical because we cannot afford to leave even 1 system in the network unprotected, and as observed it happens most of the time that some systems in the network are without SEP and/or not up to date/not patched and those machines are later found to be the source/attacking machines. We can simply check this in SEPM-clients tab and comparing the number with the total number of clients in the LAN.

- Get the exact number of systems infected and the threats names.
SEPM-Monitors-logs-risk logs would help

- Confirm if server is infected too
Find possible infection in Server..check scheduled tasks/autorun.inf in open shares/unknown services/disabled services [BITS/AU etc.] [analyzing ESUG log would be a good idea]

-Disable Auto play from GPO [across the domain] we can use application device control policy as well. [see the links in the bottom of this article]

-Disable Task Scheduler service [If it’s not being used in the network]

-Back trace the “source systems” from where the attack is being originated

This is one more critical steps to narrow down the network. We need to find that from which systems actually the attack is being originated.
We can find this out by 3 ways ..

1-IPS logs [log only mode coz’ block mode will block the system for 600 secs which the customer may not like]
2-Event viewer-Security logs- Failure Audits [We’ve to enable the Failure audits in GPO if not enabled already]
3-Net logon debug log [see the links in the bottom of this article]

-Once we find the above information we can use Nlparse from Microsoft account lockout tools to analyze Netlogon.log [see the links in the bottom of this article]

-The above logs will give us an idea about the systems which are attacking other systems in the network.

-We need to first target these machines and get the ESUG logs from them.

-We need to avoid logging in to the system as “domain administrator” coz’ by doing this we would make the job of the threat more easy as it uses {impersonates} the currently logged on account to access/infect other systems in the network. IF ‘isolating’ these systems is possible then that would certainly help us.

-We need to confirm the patch KB 958644/AV status /disabled services / registry entries on these systems. [ESUG]

-Once these systems are cleaned hopefully the situation would be under control.


For the MS specific steps[Editing GPO / enabling Netlogon log] we may consult MS tech support if the customer has support contract with MS[To be on the safer side] If not then we can help him as a best effort support.

Assuming that all infections came from outside the network, will the number of infections still have a noticeable decrease?

Peterpan, you may want to try this out in your network too.

Dear Sir, i'm so happy that at the end. you solved w32.downadup problem.
As you mention before ( on July 2nd, 2009, on first computer that infected via w32.downadup ) , the  KB958644 was installed & that system was updated . But when you Again, say that Solved your problem, You said that the problem solved because of Security update :
You said that at 3 weeks 4 days ago   " I think so i solve this problem. i didnt take attach from yesterday. I check updates and one security updates need. (why wsus don't install it I don't know. I am not sure this happend for this security update.) "

I think that, you did Lot of things ( Install Security updates, update virus definitions, some security rules, some tricks & meantime, Symantec did someting inside Vir. Def. ) & suddenly you see that your problem solved.
Please refer to old post & related comments & answer me. because as you see, some other peoples also have same problem with this Virus & Still continue ... & they can't use you solution to finish it.
And you know that this virus can make Many Problems for Network, Even for your Position, am i right?

Many thank's

I week two days ago If you have same problem please do it this
solition is

Hello Peterpan.
I did it like this.
First Check all security and critical updates. all must be install on machine.
Than update SEP.
close autorun.inf both of Active Directory Group Policy and SEP "Application and device manager"
and change your  antivirus and antispy rule. I change it first action and second action.
first action is delete second is move to quarantine.

autorun.inf is only one way that w32.downadup infects a PC. There are also alerts on our network indicating a W32.Downadup infection but from the Temporary Internet Files folder and it is not of the filename autorun.inf. They usually have .jpg extensions.

Dear Fatih

I'm sure that you remove w32.downadup from your servers & finnaly, solved w32.downadup story by yourself, because
of so many tries you did. But please think of your old topics about what you said about the points like ( Security Patches,
Security Updates, Hot Fixes & Even some configuration you did in your Networks by Closing USB via Symantec Endpoint )
& some others you said before ...
As you mention before @ July 2nd, 2009, "on first computer that infected via w32.downadup, the KB958644 was installed & that
system was updated" you said. Am i right?
But again, when your problem Solved, you said that the problem solved because of Security update :
You said that at 3 weeks 4 days ago   " I think so i solve this problem. i didnt take attach from yesterday. I check updates
and one security updates need. why wsus don't install it I don't know. " you said.

Forthis reasons, i am not sure that, as you mentioned, W32.Downadup story was finished at your side. I think that, you did
Lot of things (Install Security updates, Update virus def. & some add Security Rules, did Some tricks & also meantime,
Symantec Team, did someting inside Vir. Def. & suddenly, you see that your problem solved & think about last job you did.
Please refer to old post & related comments & answer me, because as you see, some other peoples also have same problem with
this Virus & Still the story continue ... & they can't use your solution to finish it. By the way, you know very well that
this virus can make Many Problems for Network, Even for Network Administrators Positions too. Isn't it ?

Many thank's

Patch KB958644 is famous for Downadup but nowadays thats not all you have to have all the security patches updated to be free from this threat.

@ Nourbakhsh -- If you have one system that is not patched with the above patch in your whole network it enough to infect the computers that it can communicate with no matter what definitions it has
Yes if your computer has updated AV defs it won't let it propogate or work as it does but it will get into your computer due to high encryption methods used.

So if you think you have all the systems patched with the above KB and all updated virus definitions still you are infected with Downadup then you are wrong.
There is one guy who is either not having this patch / does have updated defs / not using AV (turned off/un-installed) etall

There are many ways of find this culprit computer two of them present in house with SEP is the IPS logs/alerts and Risk Tracer feature of Auto-Protect for more information read this article
https://www-secure.symantec.com/connect/articles/worms-and-threats-spread-across-networks-network-shares-have-become-more-common-recent-yea-0
And there other ways of doing it using Nmap or Netlogon logs or security audit most of them are only use when it is locking your user accounts but Risk Tracer works in all scenarios..

Once you find that system remove it from network patch it updated the AV defs..bring it back to the network.
