Hi. I have recently been infected with Spyware. my homepage got changed, some junk got added to my favorites folder/desktop. i found a wp.exe and wp.bmp in My Computer. my wallpaper was changed to a blue error screen, right clicking the desktop, i noticed that the desktop tab was missing.. just the screen saver and settings tabs were there. I ran Adaware, Spybot Search and Destroy, that got rid of it, but i couldn't get my old desktop back. i opened regedit, edited the wallpaper/currenentwallpaper/originalwallpaper the correct jpg, instead of the wp.bmp from the spyware, but it didn't work.

i found out it was DyFuCa. I was told this is one of the worst, so if i could get any help removing it, i would appreciate it.


I booted in safe mode, deleted the Popuper.exe but am still having problems.

Popup.exe is gone. i took out some suspicous stuff with HJT. i think i got rid of the popups and the dialers. i still can't change my desktop wallpaper. im guessing the virus changed something in the registry... right clicking desktop, going into properties. i still only have the Screen Saver and Settings tabs. missing the others.

(EDIT) still getting error icons on the toolbar, saying im infected with a virus. asking me to click on it. (wich bring up popups)
just removed F2 - REG:system.ini: Shell=explorer.exe, msmsgs.exe

regedit-current user-controll panel-desktop shows the correct .jpg as my wallpaper. but it's still black.

Launch Notepad, and copy/paste the box below into a new notepad file. Change the "save as" type to "All Files". Save it as Unreg.bat on your Desktop.

regsvr32 /u C:\WINDOWS\system32\ahbi.dll

Locate Unreg.bat on your Desktop and double-click on it.

Then, Press CTRL ALT DELETE and click on the Processes tab. End the following process:

C:\wp.exe

While in safe mode, run Ad-Aware - but configure it for a full system scan first by following the instructions below:

In the Ad-Aware main window, click on the gear icon at the top of the screen to open the preferences window. In the "General" window, make sure the following options are selected:

Click on "Scanning Engine" and make sure the following options are selected:

2) Obtain command line of scanned processes
3) Scan registry for all users instead of current user only

2) Write-protect system files after repair (Hosts file, etc)

Click on "Proceed" to save the preferences. Then please click the "Start" button on the bottom left side to begin a scan. Select "Use custom scanning options" and then click "Next". Ad-Aware will then scan for malware. When it is finished, make sure any objects listed in RED are selected and click "Next" to remove the objects.

Any ideas on how to fix the wallpaper issue?

Have you already tried right-clicking to see if the tabs are still grayed-out?

Please run this online virus scan:
ActiveScan

Copy the results from ActiveScan and paste them here.

I also need you to reboot into Safe Mode and delete the following file (it was on your first log, but not on the latest logs), but it may still be there:

C:\WINDOWS\system32\helper.exe

These files are associated with the Trojan and need to be deleted:

C:\wp.bmp
C:\Windows\sites.ini
C:\Windows\System32\intmonp.exe (if this file is still there then popupers.exe is still there because they monitor each other and popupers will regenerate if deleted)

So we may have to get out the big guns (a program called Killbox) to kill those files at the same time.

What you have is a fairly new Trojan Dropper.

Download, install, and run CleanUp! Then follow the instructions below:

Please read these instructions carefully

*Click Here to download Killbox by Option^Explicit.
*Extract the program to your desktop and double-click on its folder, then double-click on Killbox.exe to start the program.
*In the killbox program, select the Delete on Reboot option.
*In the field labeled Full Path of File to Delete enter the file paths listed below ONE AT A TIME (EXACTLY as it appears, please double check to make sure! I would just copy each file path and paste it in the field):

C:\WINDOWS\system32\wldr.dll
C:\Documents and Settings\Evil Acid\Local Settings\Temp\temp.frA206
C:\Documents and Settings\Evil Acid\Local Settings\Temp\temp.frD0D9
C:\RECYCLER\S-1-5-21-1177238915-515967899-725345543-1003\Dc235.exe
C:\WINDOWS\Downloaded Program Files\DeskAdX.dll
C:\WINDOWS\system32\xmlparse.dll
C:\WINDOWS\system32\xmltok.dll
C:\Windows\System32\intmonp.exe
C:\Windows\System32\popuper.exe
C:\Windows\sites.ini


Press the button that looks like a red circle with a white X in it after each one. When it asks if you would like to delete on reboot, press the YES button, when it asks if you want to reboot now, press the NO button. Do this after each one until you have entered the LAST file path I have listed above. After that LAST file path has been entered press the YES button at both prompts so that your computer restarts.

You'll have to still try to delete those with killbox since popupers and intmonp.exe monitor each other. We'll just get them all with killbox, don't worry about manually deleting them. Just follow the instructions in my previous post. I'll see what other files may be on your computer from these trojans.

You're welcome :tazz:

Ok, I need you to find this folder:
C:\Program Files\Virtual Maid

It should have some BMP images and a dll file in it. Either way, delete the whole folder.

Then I need you to look for this folder:
C:\Windows\System32\LogFiles

This is where the Trojans were dropped. They are supposed to delete themselves after execution, but we're going to look anyway because I'm curious to see if they actually do (or any similar names):

T54111925.so
H53131712.so
A54102200.so
S53252000.so
A04111925.so
M54111925.so
P54111925.so

Delete this whole folder:
C:\Windows\System32\LogFiles

Did your computer restart after you ran Killbox?? Follow the same instructions above for killbox and put these 2 file paths in (I used the wrong file path for popupers so we have to delete them both again.) Your computer is supposed to restart automatically after putting them all in and clicking yes on both prompts. if it doesn't restart automatically you need to restart it after setting these file paths to be deleted on reboot:

C:\Windows\System32\intmonp.exe
C:\Windows\popuper.exe

i had previously deleted the virtual maid threw control panel-Add/Remove programs. so it wasnt there.

C:\Windows\System32\LogFiles
had 1 file
A04111925.so

deleted the folder.

using Killbox with
C:\Windows\System32\intmonp.exe
C:\Windows\popupers.exe

i get http://img189.echo.c...33/kbpop9ob.jpg saying they are already deleted. (wich sounds like a good thing)

Did your computer restart after you ran Killbox??

yes, i clicked Yes on "would you like to reboot now?" prompt after the last entry.

Go ahead and restart your computer, because I know one of the files wasn't deleted previously because I gave you the wrong file path. After you restart they should both be gone.
