TROJ_DLDR.OO virus

[drev]

Hello there

PC-cillin 2002 RealTime Monitor has detected virus TROJ_DLDR.OO, located within file C:/WINDOWS/System32/lsd_f3.dll

PC-cillin says it is unable to quarantine or clean the virus. I have run a HiJackThis log but none of the strings look related to the virus. Do you have any suggestions re what I can do? Also, I have done a google search on the virus but there are no results.

I am running Windows XP. HiJackThis log is below.

Many thanks in advance.

Did you try having PC-cillin do a scan in Safe Mode ?

Here a couple free online Virus scan that NooNoo recommends people try to find and maybe kill those ;

That is a Trojan, you want to get rid of that. Best bet is to boot into Safe Mode and find and delete it. The info I found on that Trojan is located here:

Also, you should get rid of these as well;

I ran HiJackThis in safe mode and got rid of the try-this-search strings and also the w32_ss.exe line. Then when I tried to delete the .exe file itself in the System32 folder it wouldn't let me and a message appeared 'Cannot delete w32_ss: it is being used by another person or program. Close any programs that might be using the file and try again.'

However, I did run Pandasoftware virus scan as recommended by GrandDad, and it seemed to locate and disinfect 5 infected files, one of which was a Haxdoor trojan (the explanation on the site you told me to link to said the w32_ss.exe is a Haxdoor trojan. The scan log is here:

Getting a bit confused now!

Oh, and when I ran PC-cillin 2002 RealTime Monitor again, it still picked up virus TROJ_DLDR.OO, located within file C:/WINDOWS/System32/lsd_f3.dll!

drev, try these removal instructions

[Jeff316]

Drev-

I was fixing a machine for a family friend (2200 viruses and over 100 bad things detected by spybot). (Noo Noo your "sticky" instructions were most helpful)

There was one file that I could not delete, wdm.dll (backdoor.ba trojan) - here's what I did:

Look in the system32 folder. Can you see the file? (you can probably go to a cmd line and see the file but not in explorer).

If not you'll need to change a key in the registry, look here: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows for a value called Appinit_Dlls.

Make a backup before you change anything.

If you can see the file, boot into safe mode, log in as administrator and take ownership of the file. then add the adminsitrator account to have full control and remove "everyone", finally remove the read only attribute. Now delete it.

This worked on a winXP home edition with NTFS filesystem. If you're running something different YMMV.

I found out that this virus is actually a derivation of the TROJ_SMALL.IP virus. What I did to get rid of it was go into registry editor (make back-up first!) and double-click the following:
HKEY_LOCAL_MACHINE>Software>Microsoft>WindowsNT>
CurrentVersion>Winlogon>Notify>f3dsl
Delete the key:
f3dsl
In the left panel, click on:
HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Servic es>iesprt
Delete the key:
iesprt

I then re-ran PC-Cillin and it was able to quarantine the affected file.

This seems to have done the trick.

Belated thanks for all your help!
