Comment:

Since a few hours I find a new file SCRSVR.exe in my Windows directory. A entry in my WIN.INI tries to run this. If I delete it and remove the line in WIN.INI it comes back from time to time.

All comments highly welcome

I believe thats just a screensaver...? does your screensaver work when deleted? maybe it comes back because you are reinstalling or re enabling it. This is purely a guess... look at the files' properties & post more info on it. (find files & folders & search it)

Thank you Norm! i was just looking into this more after seeing another post on it, NOT in virus databases or search engines yet? (confusion with SCRSVR.exe & SCRSRV.exe between the 2 posts) I would hate to mislead anyone into believing they are safe when not! There was no info in virus databases or search engines yet. wow real new one too. thats where these forums are important to read once in a while... keep up on things - issues like this. Learnin every day. A2Z

I got it too, on 9/28. At the same time, my modem light indicated I'm uploading steadily, about 4mb before it finally quit. Each time I deleted it and changed win.ini back, it came back as soon as I connected. Finally wrote over it with a text file with the same name and saved it read only.

Hey, i'm a newcomer.
I find here by google..
My mate got same virus today, and i'm searching the solution.
But it seems there is none for now.

Here is my condition:
5 computer are in same room with familiar network setting, that says OOO.OOO.OOO.10~15.
But only the one who shares its harddisk has been infected.
Is it reasonable if i think that the virus infected by sharing disk?

Greetings, from Chile :P
(My apologizes for my english... i don't use it often)

Well, i have detected the scrsvr.exe file on 2 PCs aprox. the 28/09/02... it appears to be infected on 27th night.
Deleting the file and changing win.ini and the register will not help. Aparently, the file is transmited directly over the net, withouth need of download. :/

Well, i think than i have take ride of the infection in some way. What i have made is:

·edited register and deleted any reference to scrsvr.exe
·exit from windows, to ms-dos mode
·enter to c:\windows and deleted scrsvr.exe
·using edit, created a file called scrsvr.exe (0kb)
·changing attributes to +R -A
·edited win.ini and deleted the reference to scrsvr.exe on run=
·reboot, and the file is no longer loaded.

I have been over 32 hours without changes on my 0kb file, and no other files have tried to load... Plus, there have been several "nbsession" trying to connect my pc, and still there is no change... i think (and i hope...)

Well... and, that's all...

(again, my apologizes for my english... :P)

Hi Scrsvr.exe appears to be a trojan hiding as an innocuos file.

It is transmittted apparently by opening a email message that contains it (not by downloading an attachment)

I got it yesterday. It appears to trsnsmit information directly to its source.

It achieves this by logging onto the internet automatically.

Firstly stop it transmitting by changing your internet settings to not log on automatically.

If you have a dialup this is easy, if you are on a network this is more difficult so advise your system admin.

This Virus/Trojan disables your firewall if installed and is invisible to both mcafee and Norton.

It amends your windows installation file and system data files.

It cannot be removed in windows.

It must be removed in DOS - a big problem if you have XP.

Identify that your machine has it by running a find/search for scrsvr.exe it will be in your windows directory.

Do not attempt to delete it here.

Close down machine and use DOS to delete file scrsvr.exe from your Windows directory.

Reboot machine and you will receive two error messages ignore them.

After reboot use edit to remove the run line for scrsvr.exe from Win.ini file.

Delete all emails and empty deleted items folders.


This should cure the problem unless you are re-infected with a new email.

Ensure that your firewall is reset together with your antivirus to block scrsvr.exe

As a precaution if you use your computer for any secure transactions that involve Banks/Building Societies/Credit cards etc arrange with your bank etc to change all computer passwords with immediate effect.

Regards

John

Thanks a lot Braxat.
I could not find the file scrsvr.exe in the registry, neither in windows directory. But Norton deteted it and quarantined. There were 500 tmp files. I need to check up if these were created by " scrsvr.exe "I got this 4 time every 3/4 minutes. Then I enabled NIS 2002 , after which it did not appear.

I followed Braxat's instructions. It is quite a great advise. Thanks.

SO far no recurrence..

will update if any !!!

It looks like it's able to access your C drive in windows ME, even if you have a password. I turned off filesharing, removed the file. The moment I turn sharing back on, within minutes, i see 3 computers attaching to post 139 and uploading that file again. Eventhough I just changed the password.

new virus " WORM_OPASOFT.A "


At this time of analysis, the download site is not accessible and is either blocked or is currently down.

This worm also scans for the computer name and domain name of machines connected to the network. It then sends this information to the download site.

NOTE: Before proceding to remove this malware, Trend Micro recommends that infected machines be temporarily disconnected from the network.

Removing Autostart Entries from the Registry

Removing autostart entries from the registry prevents the malware from executing during startup.

Open Registry Editor. To do this, click Start>Run, type REGEDIT, then press Enter.
In the left panel, double-click the following:
HKEY_LOCAL_MACHINE>Software>Microsoft>
Windows>CurrentVersion>Run
In the right panel, locate and delete the entry or entries:
ScrSvr = %Windows%\ScrSVr.exe
*where %Windows% is the Windows directory, which is usually C:\Windows or C:\WINNT.
Close Registry Editor.
Removing Autostart Entries from System Files


A malware may modify system files so that it automatically executes at every Windows startup. These startup entries must be removed before the system can be restarted safely.

Open System Configuration Editor. To do this, click Start>Run, type SYSEDIT, then press Enter.
In System Configuration Editor, select the WIN.INI window.
Under the [windows] section, locate the line that begins with:
run =
From the same line, delete the malware path and filename:
?Windows%\SCRSVR.EXE?br> *where %Windows% is the Windows directory, which is usually C:\Windows or C:\WINNT.
Close System Configuration Editor and click Yes when prompted to save.
Terminating the Malware Program

This procedure terminates the running malware process from memory.

Open Windows Task Manager.
On Windows 9x/ME systems
Simply restart your machine and continue with the next procedure Running Trend Micro Antivirus.
On Windows NT/2000/XP systems, press
CTRL+SHIFT+ESC, and click the Processes tab.
In the list of running programs, locate the process:
SCRSVR.EXE
Select the malware process, then press the End Process button.
To check if the malware process has been terminated, close Task Manager, and then open it again.
Close Task Manager.

To Janette,
The way to delete the line from win.is is to double click the file, and delete the line with the del key in your keyboard(the line is at the begining).
To delete the scrsvr.exe file in DOS, you have to go to c:\Windows by writing cd windows (if you are not yet). When you are in c:\Windows, you put del scrsvr.exe and thats all!

Hi,
I thought I would post detailed directions to what I did to remove this virus. Mostly I followed the instructions that I saw other people post in this discussion, but I decided to be very detailed so that everyone could follow it. It would be helpful to print this out first if you decide to do it.

Click on Start button, then on Run. Type in MSCONFIG and hit enter. A window will pop up, and you should click on the Startup tab. There will be a little scroll list of all the programs that startup when you turn on your computer. Look for Scrsvr and uncheck the box next to it. Click OK, and Windows will ask if you want to restart, click No. You don't want to restart, you want to shut down completely.

Close down your computer and restart with a boot disk, which will bring you to DOS. (If you don't know how to make a boot disk, search the internet for some instructions.) Then use these commands to delete scrsvr.exe from your Windows directory.
Type in: del c:\windows\scrsvr.exe
Press Enter
Type in: Edit and then Press Enter
(If you have a good boot disk this will bring up a small application that will allow you to make a fake scrsvr file and keep the virus from duplicating itself again.)
A blue screen will appear. Press Alt and F at the same time. Use your arrow keys to move down and highlight Save As in the menu that appears. Press Enter.
Type in: scrsvr.exe in the window that appears next. Then use Tab to get to the Save button and press Enter again.
Then you're back to the blue screen. Once again Press Alt and F at the same time. Use your arrow keys to move down and highlight Exit in the menu that appears. Press Enter.
You should now be back to the black and white screen.
Type in: attrib +r c:\windows\scrsvr.exe
Press enter. The fake scrsvr you created now can't be deleted or overwritten by the virus. You're done in Dos, so turn off your computer, remove the boot disk, and reload to Windows.

You will probably see a little message saying "You are using Selective startup for troubleshooting". Just click the check box on this and click ok so that you won't have to see it anymore. It is just talking about the first step you did when you changed MSCONFIG.

Open Notepad (look for it in your Start Menu, under Programs > Accessories).
Click on the File menu, then on Open. A window pops up. Next to "Files of Type" at the bottom of the screen, click on the down arrow and select "All Files". Then browse your computer to get into the Windows folder on C drive. Find a file called Win.ini and open it. On my computer there was a line near the top that was set to load scrsvr.exe when the computer started. It looked like "C:\Windows\scrsvr.exe" and I just deleted it right out of there. Then click File, and Save. Exit this program.

Click on Start button again, then on Run. Type in REGEDIT and hit enter. Click on the Edit menu in the window that comes up, and then on Find. Type in scrsvr in the box and then click on Find Next button. It will locate scrsvr in your Registry, all you have to do is right click on it and delete it. Close this window when you're done.

That's all I did, besides configuring McAfee Firewall to block scrsvr.exe from accessing the internet. Please note that I am running Windows ME and your computer might be a little different from mine.

I hope this works, I'll watch my computer for a few days and see. Good luck!

Hi all, i had this file scrsvr in my windows directory. It said it was modified in June 2106. I noticed it was there because every time i booted up my machine it would try to connect to the internet. I ran Msconfig only to find the entries =run and SCRSVR in there. One was leading to the win.ini so i removed it from there. Restarted machine. Didnt try to connect. Problem solved i thought! The following day i went on the internet. Shut down my machine. Booted it up next day and it tried to connect. Straight after that i go to delete it, it says File being used by windows. I run Inoculate 6 on it. No viruses detected. Think nothing of it. However when i went on the interenet again i get inoculate 6 telling me the file scrsvr is infected by WIN95/space.1445 so i cure it. No problem. Seems to have worked fine. Anyone else get that virus?

Anyone using cable as a conection had problems sending and receiving data after scrsvr.exe gets into place? My computer blocks a few seconds till I press CTRL+ALT+DEL and close the not responding program which is... scrsve.exe

After that, no more transfer over the network...

Well, i don't know what else to do to get rid of it right now. so i created a batch file to delete it apon upliad to my system.

-Open note pad-
type the following:

del c:\windows\scrsvr.exe
c:\mybatchfile.bat

save as mybatchfile.bat SAVE TYPE AS "all files"

You can change the name to what ever u want, just remeber to change what you type in note pad.

Execute the batch file. It will run a continual loop deleting the file as soon as it is uploaded.

Untill I can find a way to rid it I use a cheap way of riding the file. I have tryed everything and cant find a way.

My mom managed to quarantine it with Norton as soon as she turned on the computer but I don't know if it's completely gone. On the startup it says "Cannot find the file 'scrsvr.exe' (or one of its components). Make sure the path and filename are correct and that all required libraries are available." and after you click OK for that, another pops up saying "Could not load or run 'scrsvr.exe' specified in the WIN.INI file. Make sure the file exists on your computer or remove the reference to it in the WIN.INI file." I don't think that it's completely gone because when I check my WIN.INI (which is a Notepad file) it says some stuff about scrsvr.exe at the top. How do I remove ALL of it? Please be clear. I don't know a lot about computers so if you tell me to do some stuff, I won't understand you at all.

Hi,

i've got the virus since 28/29.9.
I've already deleted the entry in the
win.ini file and search the registry for
entries with "scrsvr". Also delete the file
but i won't help. After I connect to the
internet the scrsvr.exe comes back on my
pc. I've got the newest update for NAV2002
(bkdr.opasoft) but it only finds scrsvr.exe as a virus an no other viruses. The REMOVVAL TOOL don't find anything on my pc. So the scrsvr.exe comes again and again... :(
If created a fake scrsvr.exe file and it gets a write protection also the win.ini gets write protection. So at the moment my system will not infected by this file again. But why the file comes always back on my system, if the fake would'nt exist??????????????????????????

I also infected by scrsvr.exe at 09/28/02
At first I did not know what it was, so I used DOS command: Type scrsvr.exe then I found about opasoft.com. - one of the text line shows ... opasoft.com

Today(10/10/02) I found it was virus, so I removed scrsvr.exe file and registry too.
Then I also installed Norton FireWall.
After that I ping opasoft.com at DOS Prompt, because I want to know who is opasoft.com.

Then I got problems, It returned IP Address 127.0.0.1 which is my localhost. Then I face another problem, When I check the View Statistics at the Norton Firewall, 'localhost' was changed to 'opasoft.com'. I tested to other computer and samething was happend. After I turned off computer and turned on again, opasoft.com was disapper from VIEW STATISTICS, but as soon as I ping opasoft.com then samething happens again.

Is anyone knows what is going on?

W32.Opaserv.Worm is a network-aware worm that attempts to replicate across open network shares. It copies itself to the remote computer as a file named Scrsvr.exe. This worm also attempts to download updates from www.opasoft.com, although the site may have already been shut down. Indicators of infection include:

The existence of the files Scrsin.dat and Scrsout.dat in the root of drive C. This indicates a local infection (that is, the worm was executed on the local computer).
The existence of the Tmp.ini file in the root of drive C. This indicates a remote infection (that is, the computer was infected by a remote host).
The registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Run contains the string value ScrSvr or ScrSvrOld, which is set to c:\tmp.ini.

I GOT THIS INFORMATION OF THE NORTON ANTIVIRUS SITE.
FOR THOSE OF YOU WHO STILL HAVE THE SCRSVR.exe GO TO http://securityresponse.symantec.com/avcenter/FixOpsrv.exe
DOWNLOAD THE PROGRAM, BUT BEFORE YOU RUN IT MAKE SURE YOU CLOSE ALL PROGRAMS. IF YOU ARE ON A NETWORK OR HAVE FULL TIME INTERNET CONNECTION TO THE INTERNET. DISCONNECT THE COMPOUTER FROM THE NETWORK AND THE INTERNET. ONCE YOU HAVE DONE THAT RUN THE PROGRAM AND IT WILL TAKE ABOUT 5 TO 10 MINUTES TO SCAN ALL THE FILES. JUST INCASE YOU WANTED TO KNOW WHAT THE PROGRAM DOES, HERE ARE THE 4 THINGS:
1. Terminates all the viral W32.Opaserv.Worm processes
2. Deletes any W32.Opaserv.Worm executable files
3. Removes the viral registry entries
4. Restores the Win.ini file

I HOPE THIS WILL HELP YOU TO GET RID OF THE VIRUS.

What a bugger this has all been! Got it first on the 28th and when Norton sent a response back saying the file wasn't malicious that was the first of many headaches.

Searched high and low to try and find out what this scrsvr file was and if I really needed it on my comp. The only place I found it was on a search for the program itself and finding a site in German of the fella who made the DOS? file. I have learned alot about this evil machine since then..lol

Just yesterday in a matter of 2.5 hours, I had the file put into Norton's quarantine a total of 9 times! The odd thing is when Norton did finally recognize it as a virus and posted their removal instructions I did not have any of the values they had described.. only the scrsvr.exe file being put back continiously in my C:\Windows file and the run in my winini file... no matter how many times I would delete it.

Checked registry and nothing, checked sysedit and nothing but that one line. Was in a state of 'what in the Sam Hill am I going to do about this!' especially since some said to get into DOS with the boot disk... not this gal!, until I decided to just download all virus definition updates & the fixit tool from Norton, run it, delete all the quarantined scrsvr.exe programs and make sure that the run line was deleted in my winini file, and delete all my personal e-mail from the 27th.

Fingers crossed.. so far so good.

And I still believe Computers Are Evil! lol But so habit forming too. Hopefully now I can go back to my old 'Computer Illiterate' self and just enjoy the computer, I don't like having to know all this stuff! :-) Especially now that I'm being called a 'Computer Geek' by my family & friends! No offence to the 'real' Comp Geeks! I'm sure glad you all are around for me to ask much needed help!

Cheers!

i have just done all thats been said on this board to remove the trojan
whether it be using the automated symantec cleaner, booting in dos to edit win.ini and delete scrsvr.exe, or using regedit i have tried it.
These things ALL remove the trojan, however so long as my drive c is shared, it keeps coming back. If i dont share drive C however it doesnt return.
Could anyone PLEASE enlighten me on how to share drive C and prevent the worm returning?

I am trying to delete this virus from a friend's computer. I followed everybody's steps that are listed here, but the virus is still there. I deleted the run command from win.ini and I deleted scrsvr.exe from the registry. I have run two different Symantec tools and neither one of them find the w32.opaserv.worm but when I try to receive more of their emails Norton finds the worm and quarantines it. Is it still in the PC somewhere or do the emails that are being received also contain the worm?

Thanks for any help,
Elizabeth

Hi evereybody I keep fighting the Worm since 30th. I have 20 Win Me Computer in one Net. And everytime I Cleaned them it comes Back and Back and Back.
But in my opinion the way to find it seems to be to easy! What I mean is , the fact that it comes Back instantly after deleting the Files clearin Registry etc. seems to indicate, that there is much more than just this few things, so I guess the scrsvr.exe and all that stuff is just for camouflage to confuse us, while the actual active part of this Virus is hidden somewhere else, my opinion. What do U think

Hi
Having had this virus since the 30th of September I am nearly at my wits end. I have looked everywhere for a solution. Although Norton, McAfee, etc have posted their solutions, nothing seems to prevent it recurring.

Everything mentioned in the previous posts I have tried and the only thing I can see that works is to remove the shares. As mentioned in post 41
After removing all the shares on my PC, the virus stopped completely.

I believe this virus is scanning any computer on the internet for open network shares. Once it finds a share on a windows root drive, it writes the scrsvr.exe file and then modifies the win.ini file.

Hey presto, the next time to boot up the virus runs. When you connect to the internet, your machine starts scanning the internet for other machines with open ports to infect them.

So, as long as you are sharing your root drive, you are vunerable. If you have a fixed IP, the the virus probably store your address for targeting again.

That is my conclusion, in the absence of any other ideas.
My guess is the only way to use shares is to employ a decent firewall to prevent penetration.

Hi,

I've have had the same problems like you, but I SOLVED IT. The file scrsvr.exe comes through the Netbeui Port (Port 139). You must manually close this port.

Look on this page

Sorry but I can't explain it in "good enlgish"

Hi,

i've got the same problem but I solved it. The reason why the file is coming back is the open netbeui port (port 139). You must manually close it. Go to the TCP/IP protocol an let show you the properties in the section connections you must disable all entries (Microsoft Family Login or any other).
But only TCP/IP over your connection not the LAN.

i also beleive i have found a way to permanently solve the issue.
It is actually already mentioned on this board in post 5.
What i did was:
1) Temporarily unshare drive c (or any other shared hard drives)
2) Remove the scrsvr.exe file, remove its command line from win.ini and remove its entry in the registry (details on this in above posts)
3) Create a new text document in c:\windows, and name it scrsvr.exe, hence making it an exe file. Make sure you make this file read only
4) Share any drives unshared previously
5) Thats it, nice and simple. 24hours now and the worm hasnt returned.

After doing all the stuff recommended the day befoire yesterday I found that the machines were re-infected again. Today I booted to dos and manually removed the run commands in win.ini (was using msconfig prev), they were flagged before and not removed. Also created the blank scr file and will see tomorrow... hold thumbs...

Its gone for me now thank god. It turend out that Inoculate 6 was only finding the virus win95/space.1445. So i update my virus checker and it finds 7 viruses! 5 of them were this opaserv virus which u speak of another was backdoor/opaserv and another win95/space.1445. It cure em all and i was left to doing the registry and win.ini. I suggest you all buy copys of inoculate 6 but its price does put it out of reach of home users. It starts at £400 i think.
Thanks

A solution to the Scrsvr.exe worm:

Do all the usual stuff that you'd do for a trojan (registry [local..soft..micro..win..curr..run], win.ini, sys.ini)

Also delete scrsin.dat

Also delete scrsout.dat

delet scrs... from the run= in tmp.ini

most importantly, diable system restore:

right click on My Computer, then
f---

nevermind, NAV just detected it again on my computer. Let me know if you find a solution: buddypedro@hotmail.com

Using Zone Alarm's firewall prevented reinfection.. then after a day with it off, the virus was back. I suspect closing the port is the clean way to prevent it (this almost may prevent future strains) while the dummy text file is the dirty way (a new strain could use a new file name and beat it). I'm going to use both for now for the times when i cant use my firewall


it seems i've been getting a lot of incoming traffic on port 137. they come in pairs from many random IPs.. perhaps scrsvr.exe on other peoples computers.

maybe this worm is constantly portscanning and spreading itself..

Hi,

HERE'S THE SOLUTION....

This assumes that you already cleaned the virus
and now you want to make sure you are not
re-infected.

Ok, everyone, I found a cure for being constantly
re-infected with the Opaserv/Opasoft virus. After doing
some research (see references below) I found that
disabling the "File & Printer sharing" in Windows did
the trick to keep me from being re-infected after cleaning
the virus. That solved the problem of being re-infected.

Below is the info that tells how the Opaserv/Opasoft virus
finds it's victims. All you need to do is be connected
to your ISP and it can get you!!! ---pete---

Full article on Opaserv Virus....
https://www.europe.f-secure.com/v-descs/opasoft.shtml

===============================================================
Excerpt from full article above...

To locate victim computers the worm scans networks by using port 137 (NETBIOS Name Service). The following subnets are scanned:

- current (infected) computer subnet (aa.bb.cc.??)

- two neighbor subnets (aa.bb.cc+1.?? , aa.bb.cc-1.??)

- random selected subnets (except several ones that are "disabled" for scanning)


In case there is reply from an IP address (i.e. there is real computer at this address), the worm also scans two subnets that are neighbor to that address.

When "reply data" is received the worm checks the special field in it. In case this field contains information that victim computer has "File and Print Sharing" service activated, the worm starts infection routine.

The infection routine specific SMB packets to the found IP address by using port 139 (NETBIOS Session Service). There packets cause the following actions:

1. The worm established connection with \\hostname\C resource on a victim machine (where "hostname" is a victim machine's name, that the worm gets this name from "reply" data).

2. In case the resource is protected by a password the worm tries to open it with all one-symbol passwords (brute-force attack).

3. In case of successful connection the worm sends its EXE file to a victim machine. The packet also contains the destination file name on the target computer: WINDOWS\scrsvr.exe

---end or excerpt---

I have sucessfully avoid this virus for a few days now, without using the dummy text file.


Basically what you need to do is this:

remove the scrsvr.exe file from your system as described above

Get to the control panel, and open Network

For each TCP/IP -> XXX

click properties, then bindings, then unbind Client for microsoft networks, File & Printer Sharing, and Microsoft Family log on.

When it asks if you'd like to bind a protocol, click no.


Repeat for each TCP/IP protocol. Then close Network by clicking OK, and reboot when asked..


Your harddrive is now closed to the outside world.
