Hello,

Horizon Technology Group, here. We've come into contact with a virus in which we've never seen, at a client's site.

This is a domain environment, DC is running SBS2008. All PCs are running Windows 7.

ISSUE:
When browsing to network drives from the PCs, or when accessing data directories on the server, we see an overlay of random files/folder names, in which all items are listed as applications (Screen shot attached).

All PCs see this on their mapped drives, but not local drives. Server sees this on one of two physical drives. All affected directories repeat some of the same files, such as "Passwords", "Porn", "Secret", "Sexy", and "X".

Trend Micro Worry Free Business Security Advanced 7.0 SP1 is installed on the server and all clients were connected prior to infection.

Ran ComboFix on one PC and have attached that log, as well.

We have begun running Trend Micro scans on all computers and the server. Any additional help identifying this virus and any information about its removal would be greatly appreciated.

Attached Files

Hello htgtechs ,
  • Welcome to Bleeping Computer.
  • My name is fireman4it and I will be helping you with your Malware problem.

    Please take note of some guidelines for this fix:
  • Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools.
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing.
  • Even if things appear to be better, it might not mean we are finished. Please continue to follow my instructions and reply back until I give you the "all clean".
  • In the upper right hand corner of the topic you will see a button called Watch Topic.I suggest you click it and select Immediate E-Mail notification and click on Proceed. This way you will be advised when we respond to your topic and facilitate the cleaning of your machine.

  • Finally, please reply using the ADD REPLY button in the lower right hand corner of your screen. Do not start a new topic. The logs that you post should be pasted directly into the reply, unless they do not fit into the post.


I would disconnect each one and run Combofix on each one. Thenn when it has been ran on all machines connect them back on the server one by one.

Here is what you are dealing with:
Trojan.Win32.Vobfus.paa
Worm:Win32/Vobfus.DO

What should we do on the server, since we can't run ComboFix?

I think this was a case of one machine getting infected then infecting the rest through the server. I would try what I said first then see what happens. I'm not an expert on servers.
