Hello please could you offer some help/advice with this problem.

I'm trying to sort out a friend's PC for him. It had lots of viruses/spyware on it, but I've been running various virus scanners and think I'm down to the last one. So far I've run:

Symantec Antivirus
AVG
Windows Defender
Ad-Aware SE
Kaspersky on-line
McAfee Stinger

The only one that has identified the problem is Kaspersky, but it doesn't fix it:

C:\Program Files\Common Files\System\deb30911.exe Infected: Trojan-Downloader.Win32.Dluca.cp skipped


The problem is causing pop-up advertising windows to appear when browsing the Internet. The problem appears to be caused by the file: deb30911.exe which is running as a process. I can kill the process and delete the file but within 30 seconds or so the file is re-created and the process starts again. Sometimes the file changes it's name (or at least the number part) and the filename is currently deb20a10.exe

I've attached a HiJackThis log below and would be very grateful for any help/advice.

Thanks,
Simon.

Howdy simonl,

Welcome to BleepingComputer. Looks like the unwanted file has another startup there that is bringing it back each time. Let's address those now, then see what else we need to repair here.


Open HijackThis, and choose None of the above, just start the program. Click Config – Misc Tools – Open process manager. From the list, click each of the following if it is present, and Kill Process. Close HijackThis.

c:\program files\common files\system\deb20a10.exe



Then you need to disable Windows Defender, as it may interfere with repairs.

* Open Windows Defender
* Click Tools
* Click General Settings
* Scroll down to Real Time Protection Options
* Uncheck Turn on Real Time Protection (recommended)
* After you uncheck this, click on the Save button
* Close Windows Defender

-----------------------------------

Download the trial version of AVG Anti-Spyware 7.5 from here and install it. This is the trial Anti-Spyware so different from your AVG there.

If you have an exisiting copy of Ewido (which this software replaces), agree to the uninstall notification and uninstall Ewido. Reboot after. Then click the AVG download file again to install the software. (If you have a paid version of Ewido installed, go here to follow the steps to upgrade that now.)

-----------

After installation, double-click the icon on your Desktop to launch AVG Anti-Spyware 7.5.

On the top of the main screen click Shield. Then click the word active to change it to inactive.

You will need to also update AVG Anti-Spyware 7.5 to the latest definition files. On the top of the main screen click Update. Then click on Start Update. The update will start and a progress bar will show the updates being installed.

Now close AVG Anti-Spyware 7.5 (don't scan just yet).

--------------------------------------

Go Here and download ATF cleaner. Click on the downloaded file to run it, and select "Select All", then click Empty Selected (and close ATF).

If you have them, also click on Firefox/Opera at the top and repeat the steps (and close ATF). Firefox/Opera will need to be closed first for the cleaning to be effective.

-------------------------------------


Close Internet Explorer and all running programs and run a scan in HijackThis. Place a check next to all of the following lines, then select “Fix Checked” and close HijackThis.

O4 - HKLM\..\Run: [ravideo] c:\windows\system32\ravideo.exe /nocomm

------------------------------------


Download Killbox from http://www.bleepingcomputer.com/files/spyware/KillBox.zip, unzip the file to your Desktop and have it ready to use.

Run Killbox and select the below files (including filepath) with your mouse, rightclick and choose Copy. Insert your mouse pointer within the box entitled "Full Filepath of File to Delete", rightclick again and choose File > Paste from Clipboard. All the files should now appear in the box (click on the Tab and check to make sure that only the files I have identified as malware and marked for deletion are there). If each file exists, it will appear in blue under that window when you click on it. Click on Delete on Reboot. You will get a message saying "File with be deleted on next reboot, click "Yes". Process and Reboot now?" Click "Yes" to reboot.

c:\program files\common files\system\deb20a10.exe
c:\windows\system32\ravideo.exe



If your computer does not restart automatically, please restart it manually. If Killbox gives you a PendingFile rename operations, manually reboot at this point.

================================================

Once your computer has fully rebooted, reboot again into Safe Mode (at startup tap the F8 key and select Safe Mode).


Make sure all windows are closed and run AVG Anti-Spyware 7.5. Click Scanner, then click on the Scan tab. Click Complete System Scan to begin scanning. When the scan is complete click Recommended Action and change it to Quarantine. Then click Apply all actions.

Once the scan has finished, click the Save report button, then click Save Report As. This will create a text file. Make sure you know where to find this file again.

--------------------------------------

Reboot to normal mode, and go Here and download Silent Runners to your desktop. Run it, and post back here the log it creates. If your AV queries the script, allow it to run. It's not malicious. It will create a file named Startup Programs, and will notify when the scan is complete. Copy the log from the Startup Programs file back here, along with the AVG log and a new HijackThis scan please. You can use separate posts here if needed.

Hi Jintan,

Thanks for taking the time to post such a detailed reply - I feel guilty I haven't followed all your instructions !

I ran AVG again and it updated its virus definitions. I then ran another full scan and this time it found the deb20a10.exe file - it reported it was a 'Downloader.Generic.HFL' type virus. It also 'cleaned' the infection which seems to have fixed things. Several reboots later and a lot of web browsing and there haven't been any annoying popups, and there's no 'deb...' processes running or files in that directory.

I checked out the 'ravideo.exe' file you mentioned - it was in the system32 directory but had a zero file size. There wasn't an ravideo process running, so I just deleted the file, and removed it from the registry startup. Possibly one of the antivirus programs I'd run previously had 'cleaned' the file ?

I've now returned the PC to my firend and I've not heard of any problems so I think he's happy with it. Hopefully he stays clear of the 'porn' web sites which probably led to his problems in the first place !

Anyway thanks again and best wishes,
Simon

It wouldn't do much good guessing some answers to all that simonl, without reviewing any results from the steps suggested. But good that you accomplished what all you could, and I appreciate your providing the update. Be well.
