Welcome to Major Geeks!


Uninstall the below old versions of software:
Java(TM) 6 Update 29
Java(TM) SE Development Kit 6 Update 23

Now we need to use ComboFix

• Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
  • If it is not on your Desktop, the below will not work.
• Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
• If ComboFix tells you it has expired or need to be updated to a new version, make sure you allow it to update.
• Open Notepad and copy/paste the text in the below quote box into it:

• Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
• At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
• You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
• Now use your mouse to drag CFscript.txt on top of ComboFix.exe
• Follow the prompts.
• When it finishes, a log will be produced named c:\combofix.txt
• I will ask for this log below

Note:

Do not mouseclick combofix's window while it is running. That may cause it to stall.

If after running Combofix you discover none of your programs will open up because you recieve the following error: Illegal operation attempted on a registry key that has been marked for deletion then you will need to reboot your computer which will normally fix this problem.

After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

Now run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).

Then attach the below logs:

• C:\ComboFix.txt
• C:\MGlogs.zip

Make sure you tell me how things are working now!

Ok,

I followed all the steps and here are the log files. During combofix, I temporarily disabled AVG.

After running combofix, a reboot had to be done, and AVG starts with reboot. Immediatly after reboot, AVG gave again the same error that win32/Kryptic was detected...

Seems not to be solved yet...

[hvdb]

Also in C:WINDOWS\SYSTEM32\ directory there is again a new dll file:

C:\WINDOWS\system32\18444350041.dll

[hvdb]

and got also attached error now from AVG...

[chaslang]

As stated in the READ & RUN ME, you will have to uninstall AVG now to avoid having it get in our way. Once we have totally cleaned your PC, you will be able to reinstall it. So uninstall it now, while I look thru your new logs.

Now we need to use ComboFix

• Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
  • If it is not on your Desktop, the below will not work.

Ok,

Have retried with all AVG services stopped, this worked perfectly as i am a bit afraid of uininstalling. This time, after reboot combofix ran without any interference from AVG.

Find attached the 2 log files requested, and also the warning windows firewall showed after the reboot generated by combofix. Basically it says Windows firewall has blocked certain fucntions of windows explorer. It has blocked the program to accepts incoming connections from network or internet. I choose the option to keep blocking.

[hvdb]

Also, a new "suspicious" dll file appears in

C:\WINDOWS\system32\857189341.dll

Created after combofix has run. Combofix.txt was created at 9:56, the dll file was created at 9:57...

[hvdb]

Also got AVG warning (after I re-enabled the avg services) not immediatly but an hour later.

Items in system restore are not currently problems. We will fix/remove them when we get to final instructions.

You may still have to remove AVG. We will see. It is not protecting you from this infection anyway and it is obviously incapable of remving it.



Please download OTL by OldTimer.

• Save it to your desktop.
• Double click on the OTL icon on your desktop. (If running Vista or Win7 right-click and select Run as Administrator)
• Check the "Scan All Users" checkbox.
• Check the "Standard Output".
• Change the setting of "Drivers" and "Services" to "All"
• Copy the text in the code box below and paste it into the Customs Scans/Fixes text-field.

Also run GMER per the below and attach the log:

GMER - running with a random name

[chaslang]

One more request! Please put a copy of the C:\WINDOWS\system32\857189341.dll file into a ZIP file and attach it to your next message.

[hvdb]

Just to be sure I don't lose it during cleanup, here is already the dll file in rar format.

Those last to scans I requested with OTL and GMER do not fix anything. They are just scans to look for information. Once I have the logs from them, we will continue.

The DLL file did not contain any identifying information. And virus scans on it do not show it to be a problem:

[hvdb]

OK,

For the moment, symptoms seem to have disappeared.

Do the logs confirm all is OK?
