Hi,

I'm having some trouble in removing Virtumonde virus from a computer at work. Spybot S&D has identified the virus as Virtumonde, but neither the Trojan.Vundo removal tool or Virtumondebegone find and delete it when i run them.
Symantec Antivirus finds a Downloader Risk each time i startup in the following folder:
C:\Documents and Settings\Administrator\Local Settings\Temp\Temporary Internet Files\Content.IE5\8PMBO52N\valera[1], but can only partially delete it. I've deleted it in Safemode but it keeps on coming back..
Please help. I've been trying to figure this out all day and my head is starting to hurt :thumbsup:

Hijack this log is attached.
Thanks in advance!

Hello Triona,

Select the following with HijackThis.
With all windows (including this one!) closed (close browser/explorer windows), please select "fix checked"

O2 - BHO: (no name) - {89AD4D75-2429-462e-BD4E-443F233F6033} - C:\WINDOWS\system32\eypfafej.dll
O2 - BHO: (no name) - {A849423E-1F22-4017-8159-B19615374A77} - C:\WINDOWS\system32\geedc.dll


Reboot your computer.

*********************


If you have used Combofix before, please delete the version you are having and redownload it again, because Combofix is being updated everyday.

If your Antivirus or any other realtime scanner is displaying an alert after you downloaded Combofix or while you use Combofix, please disable your scanner and redownload Combofix again. Because some scanners may see some combofix related components as suspicious and block or delete them while there's nothing wrong with them.



1. Download this file - combofix.exe to your Desktop.
Note:
It is important that it is saved directly to your desktop

2. Double click combofix.exe & follow the prompts.
3. When finished, it shall produce a log for you, C:\ComboFix.txt. Post the ComboFix log and a fresh Hijackthis log in your next reply.
Do NOT post the ComboFix-quarantined-files.txt - unless I ask you to.

Note:
Do not mouseclick combofix's window while it's running. That may cause it to stall
If you have Norton Antivirus installed then disable script blocking so it will not interfere with the fix.

To disable Norton Script blocking Service:

* Disable the Script Blocking Service:
To open Services, click Start, point to Settings, and then click Control Panel.
Double-click Administrative Tools, and then double-click Services.
Find ScriptBlocking services, Right-click the service, and then click and then click Properties.
On the General tab, under Startup, click Disabled.
Under Service Status, click Stop button. Click Apply button.

* Disable the Script Blocking In Norton Settings:
Start Norton Antivirus.
Click Options. If a menu appears when you click Options, then click Norton Antivirus. The Norton Antivirus Options dialog box appears.
Click Script Blocking.
Uncheck Enable Script Blocking (recommended).
Click OK
You can reenable it afterwards when everything is clean again.
