Hi and Welcome to TSF!

My advice to you. Stay well away from www.3721.com !!!

Please subscribe to this thread to be notified of fixes as soon as they are posted by our Team. To do this, please click the "Thread Tools" button located in the original thread line and selecting "Subscribe to this Thread".

It would appear that your Operating System and Internet Explorer are not up to date and this seems to be contributing to your problems. Please consider going to Windows Update site and install all available Critical Updates. Patch your system with the most current security fixes and plug all the known vulnerabilities.

It's better to print out the next instructions or save them in notepad, because you also have to work in safe mode without networking support, so this page wouldn't be available then.
It is also important you don't miss a step and perform everything in the right order!!.
If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should not have any open browsers when you are carrying out the procedures below.


~~~~~~~~~~~~~~

Please download these additional files/programs :- (Do not run them unless instructed to do so)
Unplug your computer from the Internet when you have finished downloading

CleanUp! - Install

KillBox v2.0.0.175 - Save to Desktop.

Ewido Security Suite - Install & Update it's database but do not run it yet.

Nailfix - Unzip to the desktop

FindIt's.zip - Unzip to a new folder on Desktop

Process Explorer - Save to Desktop


~~~~~~~~~~~~~~

Run a scan with HiJackThis & locate an O4 entry that looks similar to this...

O4 - HKLM\..\Run: [ribxmmw] c:\windows\system32\bpgtwx.exe r

The name might be different but it resides in the system32 folder & has the alphabet "r" at the end. Close HiJackThis after you have identified this file. This is the file we need to use Process Explorer with.

Run Process Explorer and find name & location of the file you've just identified in the list of Processes.
Select the process and click Process > Suspend
Leave Process Explorer running with the process suspended until the computer reboots


~~~~~~~~~~~~~~

Copy to clipboard, all the items below by highlighting them & pressing [CTRL]+[C] on your keyboard.

name & location of the file you've just identified
c:\windows\system32\bpgtwx.exe
C:\WINDOWS\downlo~1\CnsMinEx.dll

Start KillBox

1. Go to the File menu, and choose [Paste from Clipboard].
   Verify that you've done this properly by clicking the dropdown-arrow next to the [Full Path of File to Delete] field. The filenames you pasted will be found in there.
2. Select/tick the following:
   • "Delete on Reboot"
   • "End Explorer Shell While Killing File"
   • "Unregister.dll Before Deleting" if it's not grayed out.
3. Click the RED X button.
4. Click [Yes] at the 'Delete on Reboot' prompt. Click [Yes] at the Pending Operations prompt.

* If you receive a message such as: "Component 'MsComCtl.ocx' or one of its dependencies not correctly registered: a file is missing or invalid." when trying to run TheKillbox, click here to download and run missingfilesetup.exe. Then try Killbox again.


~~~~~~~~~~~~~~

Reboot to SafeMode

1. Shut Windows down, and then turn off the computer.
2. Restart the computer. The computer begins processing a set of instructions known as the Basic Input/Output System (BIOS). What is displayed depends on the BIOS manufacturer. Some computers display a progress bar that refers to the word BIOS, while others may not display any indication that this process is happening.
3. As soon as the BIOS has finished loading, begin tapping the F8 key on your keyboard. Continue to do so until the
   Windows Advanced Options menu appears.
4. Using the arrow keys on the keyboard, scroll to and select the Safe mode menu item, and then press Enter.

~~~~~~~~~~~~~~

Run Nailfix.cmd. Your desktop and icons will disappear and reappear, and a window should open and close very quickly --- this is normal.

~~~~~~~~~~~~~~

When your done, rescan your system and make sure the following isn't present:

N3 - Netscape ... 5CSBWeb_01.src (or) 5CSBWeb_02.src

If it is, then fix that entry again; sometimes it'll take more than one pass. The actual entry is ok, and won't be deleted, it's the java wrapper marked in red that needs to be removed.


~~~~~~~~~~~~~~

Enable the viewing of Hidden files

1. Open Windows Explorer
2. Go to Tools>Folder Options>View tab.
3. enable the option for `Show hidden files and folder´
4. disable the option for `Hide file extensions for known types´
5. disable the option for `Hide protected operating system files´
6. click "Yes" to confirm & then click "OK"

Locate and delete the following folder(s), if present:

C:\Program Files\MyWebSearch\
C:\WINDOWS\system32\vidctrl\

~~~~~~~~~~~~~~

Run Cleanup! & configure the program as follows:

1. Click Options...
2. Move the arrow down to Custom CleanUp!
3. Put a check next to the following:
   • Empty Recycle Bins
   • Delete Cookies
   • Delete Prefetch files
   • [X]Scan local drives for temporary files (Please uncheck this option)
   • Cleanup! All Users
4. Click OK
5. Press the CleanUp! button to start the program. Reboot/logoff when prompted.

* CleanUp! will delete all the files in your temp folders without making a backup


~~~~~~~~~~~~~~

Run Ewido:

• Click Scanner
• Click Complete System Scan to begin scanning.
• Click OK when prompted to clean files
• With the first file it prompts to clean, select the option - "Perform action on all infections" - & choose clean and click OK.
• Once finished, click the Save report button
• Save the report to your desktop

Close Ewido
* Ewido scan would require at least an hour. I suggest that you go grab a cup of coffee & do something else while you wait for it to complete.


~~~~~~~~~~~~~~

Reboot to NormalMode.

Do an online scan at Panda

Take note the names and locations of any file it detects but fails to clean.
* Turn off the real time scanner of any existing antivirus program while performing the online scan


~~~~~~~~~~~~~~

Reboot Again & Run FindIt's.bat and wait for notepad to open a text file. Please be patient as it requires some time to finish running. Then post the results in your next reply

In your next post, please include fresh copies of:

• HiJackThis log
• List of files that Panda failed to disinfect
• Ewido's logs
• FindIt's log

Please provide details of any problems you encountered whilst performing the above steps.
